PCB Storage: What Options Do You have to Protect Your Circuit Board?

PCB Storage

Printed Circuit Boards (PCBs) must be protected to bolster the integrity. If you are looking for the PCB storage options, this article teaches you what you need to know.

What is PCB Storage?

It refers to the method of protecting a Printed Circuit Board (PCB) and preventing the same from damages.

When it comes to the storage, it is done for different reasons. While the major reason is to protect the boards from the temperature, it can also be done to keep the boards safe when transported.

What are the Stages of PCB Storage?

You may not need to store or protect the boards if there is no need for that. Hence, being sure of when the storage is required is very important.

Here are some of the important moments or stages when you need to store and protect PCBs:

1.    Store PCBs during the Fabrication Stage

Already fabricating the boards? Congratulations, but you need to beef-up on the protection. The fabrication stage is when the boardsโ€™ development commences in earnest. As such, you need to keep the boards safe from contaminants that would impede the performance once production is completed.

2.    Store the PCB Post the Fabrication

Fabricating a board is one of the important steps to the production. But after that, the board has a post-fabrication stage and this is one of the crucial moments for the protection.

During the post-fabrication stage, especially when solder mask is applied, the board is susceptible to damages that affect the solder mask.

Here are some of the reasons why the board needs to be stored before the fabrication:

  • Depending on the arrangement, the PCB manufacturer might collaborate with other companies to fabricate the board. Therefore, the transportation to and from these factories opens up the boards to excess moisture that eventually contaminate the boards.
  • Storing the PCBs during the post-fabrication stage is also a good way to protect the solder mask. This way, the mask would be protected against oxidation and other contaminants prior to the boardsโ€™ assembly.

3.    Store the Boards during the PCBA Stage

The moment you start the Printed Circuit Board Assembly (PCBA), endeavor to store it. This stage is when the PCB components or parts would be soldered to the boards.

The soldering process often leaves behind contaminants, such as flux residue. Leaving such behind often leads to impeded performances of the PCBs.

This is the reason why some PCB manufacturers have used different kinds of surface finishings to protect the copper traces.

4.    Post-Assembly Storage is Recommended

The next step after assembling a PCB is to ship it to the clients or customers. Before then, final assembly measures, such as depanelization are in place. For this reason, ensuring the proper storage of the boards is required.

Besides, the boards will be transported either by road or air. Whether they are being shipped from you to the customers or from the Contract Manufacturer (CM) to you; the goal is to protect the boards.

To do that, do any of the following:

  • Keep the boards in a PCB storage rack, which keeps them in position when in transport.
  • Use encapsulation storage methods, such as conformal coating to keep the boards safe from unstable temperatures that often impact the componentsโ€™ shelf life.

5.    Keep the Boards during the Pre-Deployment Stage

Some Printed Circuit Boards (PCBs) are not used as soon as they are assembled and shipped. Some may take several months before they are put to use. That is a bit of a lengthy time and within this period, the boards could be damaged.

Hence, when the boards are stored over a long period of time, keeping them safe becomes a priority.

Following the recommended PCB storage guidelines will come in handy at this moment. The storage stage comes under any of the following:

  • Post-assembly or after the board has been shipped and is then warehoused.
  • Between the fabrication and Printed Circuit Board Assembly (PCBA) stage.

In case you donโ€™t know what these guidelines are, we will talk about them in the next paragraphs.

The Best Printed Circuit Board Handling and Storage Guidelines

FULL PCB MANUFACTURING Quote

In this section, we introduce you to the PCB storage requirements to keep in mind, especially after the board has been assembled.

a.    PCB Handling Measures

Let us start by talking about some of the best ways to handle and keep the PCBs safe.

b.    Minimize Direct Handling

The first thought that comes to your mind is to use your hands to lift the PCBs. However, it is a bad idea. The rule is to avoid or minimize a direct contact and or handling of the PCB.

The best methods to minimize or reduce direct handling (hands-on contact) of the boards are:

  • Transport the boards on ESD PCB storage racks.
  • Place the boards in tray carts when transporting.

c.    You Should Do the Direct Handling with Care

If there is a need to use hands-on contact or direct handling, then it must be done with care. For this purpose, wear clean gloves and hold the PCBs only by the edges. Never hold at the center or place your hands at the middle.

d.    Avoid Statically-Electric Areas

If you are handling the PCBs, they must be kept away from the areas that tend to create static electricity. Examples of such areas or surfaces are:

  • Rugs and;
  • Carpets

e.    Lotion Use is a No-No

You must not use products that compromise the boardsโ€™ quality. An example is hand lotion.

f.     Prevent PCB Contamination when Transporting

Looking to transfer or transport the PCBs from one station to the other? You should do these:

  • Keep all the stations clean, as that greatly helps in reducing the risks of Foreign Object Debris (FOD) contamination.
  • Always use protective bags to package and transport the PCBs from one station to the other.

PCBA Storage Guidelines

We will now look at some of the industry-leading recommendations on how to safely store Printed Circuit Boards (PCBs).

a.    Apply Surface Finishing

Do not miss out on applying surface finishing during the PCB fabrication process. This is important because the board might require a temporal storage after the fabrication, pending when it would be assembled.

The application of an appropriate finishing at this time helps to protect the board against contamination and oxidation.

b.    Maintain a Controlled Environment

By a controlled environment, we mean that the PCB should be stored or kept where there arenโ€™t excessive temperature changes. Understanding the PCB storage temperature and humidity is also a key to getting this right.

The ideal storage temperature and humidity recommendations are:

  • 85% RH and;
  • 86หšF or below โ‰ค30หšC.

c.    Be Selective with the Components

This is where you need to pay attention to the PCB components. The rule of thumb is never to use moisture-sensitive components.

Moisture-Sensitive vs. Non-Sensitive Components

These are components that are susceptible to moisture and are not. On the one hand, the moisture-sensitive components have a limited shelf life, which ranges from a day to one year, after the assembly. On the other hand, the non-moisture-sensitive components have a longer (and sometimes unlimited) storage lifetime, which could be up to 10 years after the assembly.

Getting it Right

Choosing Surface Mount Device (SMD) components that are not moisture-centric is one side of the coin. The other side is to store these parts in a controlled environment. An environment that matches these requirements is ideal:

  • Relative Humidity (RH) of 85% and;
  • A temperature of โ‰ค30หšC or 86หšF.

d.    Utilize the Older PCBs

Sometimes, circuit boards are no longer ideal for use due to the duration they have been stored. This is why it is recommended to ship out or use the older boards first before the newer ones.

This way, the older boards will be put to good use before their periods of shelf life is elapsed.

e.    Store Circuit Boards in MBBs

Always use Moisture Barrier Bags (MBBs) to protect the PCBs. Here are some advantages of doing so:

  • MBBs have either a plastic or metallic shield that keep the PCBs safe.
  • These bags also protect the boards from contact with static electricity, especially, if you are using the boards around rugs or carpets.
  • The ideal moisture-repelling feature of the MBBs is the use of film layers to control the absorption rate of moisture.

How to Maximize MBBs

Here is how to get the most out of storing PCBs in Moisture Barrier Bags (MBBs):

  • Vacuum-seal and dry the Moisture Barrier Bags (MBBs), as that protects the bags from ESD.
  • The best MBBs to use are the ones that have desiccant pouches, as these help to keep both humidity and moisture out of the bags. The desiccant also helps to absorb any moisture that enters or is trapped inside the MBBs.

Final Thoughts: Use the PCB Storage Solutions to Your Advantage

In addition to keeping to the PCB storage guidelines, it is also important to follow the IPC standard for PCB storage. You can refer to the IPC-1601 (Printed Board Handling and Storage Guidelines) and the IPC/JEDEC J-STD-033D (Handling, Packaging, Shipping and Use of Moisture, Reflow and Process Sensitive Devices) for an idea on what it takes to effectively protect a Printed Circuit Board (PCB) within and outside the production plant/factory.

SXL vs. GXL vs. TXL Wire

SXL vs. GXL vs. TXL Wire

Automotive wires are the specific wires designed for use in automobiles. SXL, GXL and TXL are the three (3) different kinds of wires to use for such purposes. Find out in this article, how each of the wires work and how they compare to one another.

What is SXL vs. GXL vs. TXL Wire?

The trio refer to the wires used in automobiles. By automobiles, we donโ€™t just mean cars. It also extends to motorcycles, boats and RVs.

The functions of automobile wires include but are not limited to:

  • Enabling the interconnection of components and;
  • Providing sufficient insulation for these components.

For this reason, it is imperative to choose an automotive wire that provides the right kind of insulation your automobile needs. With three (3) options out there, making that decision can be a bit difficult.

The Classifications of Automotive Wires

There are two (2) major classes of wires used in automobiles. These are the:

  • Polyvinyl Chloride (PVC) and;
  • Cross-Link Polyethylene (XLPE) automotive wires

While the two are popular, the XLPE automotive wires are commonly used. Note that both XLPE and PVC refer to the different levels of insulations that these wires provide.

Introducing the XLPE Automotive Wires

SXL vs. GXL vs. TXL
SXL vs. GXL vs. TXL

We will start by defining what the Cross-Link Polyethylene (XLPE)-insulated automotive cables or wires are used for.

These are the wires with the most-durable insulation. As insulation is one property required of automotive wires, it is impressive to have the XLPE automotive cables/wires having them.

The properties include:

  • The durable insulation prevents the wires from premature aging.
  • The insulation capabilities of these cables also ensure the endurance of both abrasion and higher temperatures.
  • These wires are also versatile, which is the reason they are usable in both terminals and automotive wire connectors.

The three major types of XLPE or cross-linked automotive wires are:

  • GXL
  • SXL and;
  • TXL

What is the GXL Automotive Wire?

Let us start by defining the GXL automotive wire. It is a type of automotive wire with a thin wall. The options can be thinner, depending on what you want.

The GXL wire also has these attributes:

Conduction Capabilities

Besides the insulation, an automotive wire should also be able to handle heat conduction effectively. This is why the GXL wire is often used, due to the design as a single-conductor automotive wire.

Operational Capability

The GXL automotive wire often has a voltage rating of 50 volts and a broader temperature range of up to 125หšC.

Application

Due to the properties, including the absence of reflow and better abrasion resistance, the GXL wire is often designated for use in engine compartments. The designation is for these reasons:

  • It is recommended for use in the engine elements requiring more efforts at sustaining the heat dissipated from that direction.
  • GXL wire is also used in the high-temperature spaces where reliability and flexibility are paramount.

You can also use the GXL automotive wire in the environments and or applications that require high durability and higher heat resistances. Examples of such applications are:

  • Buses
  • Engine compartments
  • Boats
  • Trucks and;
  • Tractors

Some of the major attributes of the GXL wire include the accordance with SAE J-1128 and the operation in low temperatures.

SXL Automotive Wire

This is the โ€œstandardโ€ automotive wire and is so-called because of the thicker insulation. Hence, the regarding of the SXL wire as the โ€œgold standardโ€ in automobile wiring is because of these reasons:

  • Primary Usage: it is often called the primary automotive wire due to the prioritization, in some cases, over the other automotive wires.
  • Excellent abrasion resistance and;
  • The designation for use in the applications requiring higher resistance.

Here are some of the advantages to choosing the SXL automotive wire:

Used for Special Purposes

Thanks to the innovative properties, the SXL wire is a thick-walled wire, designed for use in special purposes. These special purposes include but are not limited to high-temperature applications, such as engine compartments.

Typical Applications

The SXL wire is best-suited for applications that require higher temperatures, as well as the ones that require less spaces.

In addition to being used in engine compartments, it can also be used for general circuit wiring.

Operational Capacities

The ideal operating temperature rating is between -40หšC-125หšC.

TXL Automotive Wire

This is the third of the automotive wires classified under XLPE. TXL is a cross-linked, extra-thin automotive wire used for applications with thinner spaces.

Here are some of the attributes:

Extra-Thin

The TXL wire is the thinnest or smallest of the automotive wires classified under XLPE. For this reason, it is the lightest and as such, have found use cases in the applications where small overall diameter is necessary.

Higher Durability

Despite the smaller diameter, the TXL wire has a higher durable. This is why it is preferred for the automotive applications that require lightweight wire.

It is also required for the automotive applications that require higher reliability, especially in the extreme cold and high-heat temperatures.

Typical Applications & Uses of the TXL Automotive Wire

As the thinnest and smallest wiring option for automobiles, it is used in the applications that require higher reliability, smaller spaces and higher durability.

Examples are buses, tractors, boats and cars.

You can also use the TXL automotive wire for the following purposes or applications:

  • The use of up to 50 volts makes it ideal for use in the medium to lightweight industrial applications.
  • You can also use the TXL automotive wire for connecting the interiors of automobiles, specifically the interiors and panels.

Operating Temperature

The temperature rating for the TXL wire is between -40หšC and 125หšC.

The Differences between SXL, GXL and TXL Automotive Wires

We have ascertained that the trio are used for connecting the elements or components in automobiles. By now, you also know that these wires are used for specific applications.

Clearly, there are some differences. Here are some of the comparisons:

TXL vs. GXL Wire

The major difference between the TXL and GXL wires is their diameter. While the TXL wire is extra-thin or the smallest, in terms of the diameter, the GXL is thin. Thus, the TXL wire is thinner than the GXL wire.

Another difference between the two is that the TXL wire is primarily used for automotive applications with a special focus on spaces, while the GXL wire is ideal for applications requiring flexibility and reliability.

Difference between SXL and GXL Wire

We can also compare the GXL and SXL wires, whereby the former has less insulation than the latter. This is the reason why the SXLโ€™s insulation is often preferred.

In a related comparison, the GXL wire holds the trump card because of the lightweight and slightly smaller diameter. That is why it is often used in the applications with limited spaces.

TXL Wire vs. SXL Wire

TXL is different from the SXL wire because it has to do with medium to lightweight applications concentrating on limited spaces; while the SXL wire is used for the high-resistance applications.

How to Choose the SXL, GXL, TXL Automotive Wires

You can choose any of these wires, depending on the use cases or typical applications. You also need to understand the overall diameter and a couple of other factors discussed below:

a.    What is the Insulation Capability?

This has to be an important consideration because the wire is meant to resist the electricity that passes through it โ€“ and to convert some of that to heat.

Therefore, the insulation capability is important, as it helps you determine the right usage. For example, the GXL wire falls between the thin and thick-wall insulation category. This makes it less-likely to provide much insulation, when compared to the SXL wire.

b.    Considering the Applications is Important

What are the wires meant for? You will find that each of these wires has specific use cases or applications. Likewise, you need to use them as designated.

First, the SXL wire is commonly used in engine compartments. The TXL wire is ideal for automotive applications with a special consideration for tighter spaces. You can use the GXL wire mostly for engine compartments and high-temperature spaces/applications, where higher heat is meant to be sustained.

c.    Take Note of the Cable/Wireโ€™s Gauge

You must also take note of the gauge that the wire or cable has. It ca be a bit technical, due to a couple of reasons.

Let us start by understanding what the gauge is all about. The gauge of an automotive wire is the measurement of the cable or wireโ€™s diameter. In this case, the following considerations are important:

  • The gauge defines the amount of electrical current that can be transmitted through the wire.
  • The wireโ€™s gauge also tells the electrical and weight resistance of the cable or wire.

Here are some of the points to note about the gauge of an automotive wire:

  • Current-Matching: the current that passes through the wire or cable must be sufficient to match the need. For example, it might be impossible to have the gauge enabling the passage of current if it is smaller.
  • Higher Gauge Equals Smaller Diameter: interestingly, there is an inverse operation of the automotive wireโ€™s gauge. In this case, the higher the number of the gauge, the lower or smaller the diameter. This is why a gauge of 0 can support up to 125 amps and have a diameter of 8.25 mm. Likewise, a higher gauge of like 20 supports only 0.080 diameter (mm) and an amp of 5.

Automotive Cable Gauge Guide

Here are some of the tips on choosing the right American Wire Gauge (AWG) for your automotive cable/wire:

  • Start by ascertaining the right amperage that your application needs. This helps you to pick the automotive cable gauge that provides the right current-passage.
  • Next, you want to go for the AWG with a lower number, as that provides more current-passing capacity. For example, an AWG of 0 supports 125 amps, an AWG of 10 supports 30 amps, while that of 20 supports 5 amps.
  • Last but not least, be sure of the desired length of the cable. This is because the size or diameter of the cable/wire decreases, as the number of the wire gauge (AWG) increases. This is why the AWG of 40 has a diameter of 0.080, that of 4 has 5.189, while an AWG of 20 has a diameter (mm) of 0.812.

What is the Cableโ€™s Voltage Drop?

Voltage must โ€œdropโ€ in an automotive cable or wire. However, you donโ€™t want this to be excessive. Let us start by defining what voltage drop means.

Voltage drop means a drop or reduction in the voltage. It is also the loss of certain amount of voltage in a circuit.

Here are additional points:

  • Voltage drop in automotive wire has to do with the amount of voltage that was lost over the length of the wire.
  • Voltage drop also has a synergy with resistance. As such, the resistance happens when the voltage travels through the wire. To this end, the voltage will drop significantly, as the resistance traveling through the wire becomes greater.

What is the Amperage of the Automotive Wire?

This time, you are considering the amperage (Amp) on a standalone basis. The amp has to do with the amount of current that the application requires and which the wire or cable can produce or offer.

What is the Resistance Capability of the Wire?

The automotive cable or wire can resist the electricity that passes through it. However, how much of that can it resist?

You are to use the resistance per unit length as the basis. It refers to the capacity of the wire to resist electricity or current from passing to a certain length.

The rule of thumb is that an increase in the American Wire Gauge (AWG) often results in a corresponding increase in the resistance per unit length. This is why an AWG of 0 has a resistance per unit length of 0.1, while an AWG of 40 has a resistance per unit length (mฮฉ/ft) of 1000.

Conclusion

The trio of SXL, GXL and TXL wires are useful in wiring automobiles, such as cars and boats. However, you must define the use cases/applications and choose the right wires for that purpose.

If you are unsure of which to go for, consult a professional to guide you.

Exploring the Basics of Vape Circuit Diagram

Vape Circuit Diagram

Vaping is the new form of smoking that has been getting hype for the past few years. However, if you are a good observer, you would want to know how does a vape work.

Well, donโ€™t be surprised to know that a special PCB mechanism is there to help you enjoy vaping all the time. The PCBs especially produced for vapes, are also becoming popular with time. Because without these PCBs, it would be impossible to make the vapes function normally. The role of a PCB in a vape is to control and manage its function as per the vape circuit diagram.

It also makes vaping safe and secure for the users. In this discussion, we are going to see how PCBs in a vape work and will also look into different aspects of the vape circuit diagram in this post! Here we go!

Basics of Vape circuit diagram

ยท       Vape circuit Power Source

A vape consists of a battery which is the main power supply for the vape. It energizes the vape electrically as well. A powerful lithium-ion battery proves to be best for vape circuits and makes vapes reliable at the same time. The vapes with such a powerful battery can last a little longer than their absence. The current keeps flowing through the vapes after we connect the battery with the respective terminals. 

ยท       Activation Button and Firing Mechanism

The next thing that you will find in a vape circuit diagram is an activation button. Basically, it is a firing mechanism present on the external side of the vape. It will complete the circuit when you press the activation button making the current start flowing through the vape, and it will also heat the coil present in the atomizer. Due to this reason, you get able to smoke through a vape, and without an activation button, it is nearly impossible.

What is the PCB Shelf Life? Extending the Life of PCBs

PCB shelf life

The PCB industry is one of the most important domains for a countryโ€™s economic growth and sustenance. However, in the old times, nobody cared about the PCB shelf life at all. It had many reasons.

Maybe due to a lack of knowledge and fewer resources, producers were unable to comprehend PCB shelf life and consider its significance for the improvement of PCBs as well.

The PCB parts come together to develop a highly efficient and industrial PCB with an optimum shelf life. We are going to dig deeper into the role of PCB shelf life for the products and the users through this post. Letโ€™s get started!

Is there any PCB Shelf Life?

If you are a PCB buyer, then make sure that you inquire about the PCB shelf life from the producer. So that you can have a vivid idea about this thing, and it can make your user experience worthwhile in the future as well.

At this point, you must know that not every PCB has the same shelf life. The PCB shelf life depends on the surface finish used for the PCBs. Some surface finishes have long shelf life while others don’t. 

PCB Assembly to Extend PCB Shelf Life

When a producer delivers the PCBs to the respective clients, one important thing to do is to include IQC for the PCB assembly. However, in some cases, if there is a problem with PCB assembly or a producer is delaying it due to some reasons, then it is advisable to secure the PCBs into small packages. For this, vacuum packages prove to be handy because they prevent moisture from seeping into the PCBs and deteriorating them gradually. 

Time for Assembly After Packaging

Bare PCB Shelf Life
Bare PCB Shelf Life

So you have packed your PCBs but what now? This is important when we talk about the PCB shelf life. One crucial thing to do after packing your PCBs is to consider their assembly, which must take place in a half year right after the packaging. The PCB surface finish that goes well with PCB shelf life is HASL. However, if you are using OSP and silver surface finish, then it will alter the PCB shelf life, which gives you just one month for PCB assembly after packaging. For tin and gold surface finish, the duration of assembly is only two months. 

Why Does the PCB Shelf Life Matter?

Now, since we are deciphering PCB shelf life, we need to know why it is important to consider. One major risk that the PCB production process faces is the complications in the soldering and developing strong solder joints to attach the PCB parts on the boards.

If oxidation takes place, this soldering gets compromised, which is not good for the health of circuit boards. The solder joints become weak due to this oxidation as well. Therefore, to prevent this from happening, producers consider using PCB components with the same PCB shelf life as boards.

The packaging of PCBs during this process also allows them to last and remain intact for at least two years. But it still depends on the type of PCB surface finish that you are using. Different surface finishes will provide different PCB shelf life. If you are relying on a lead-free surface finish, then your PCBs will have a PCB shelf life of 2 years, while for others like OSP, the shelf life is up to 6 months maximum.

Also, most of the solders and adhesives used in PCB production or PCB assembly also create their influence on the PCB shelf life on the whole. 

Managing Materials & Components for Better PCB Shelf Life

In this section, it is important to learn about the role of your PCB producer in terms of maintaining and adhering to the PCB shelf life. Due to this reason, you will be able to evaluate their performance on the basis of PCB production, material procurement, and assembly of PCB components. A good PCB producer is one who smartly keeps a record of the PCB’s shelf life.

This step comes in handy for customized PCBs where producers can stick to the prototypes board and designs and provide their clients with more insights regarding the PCB’s shelf life. When it comes to this, we at VSE are the experts in handling PCB component arrangement and developing different PCBs as per various shelf lives as per your needs. Below you will find how we are able to procure industrial-grade PCB components that improve the PCB shelf life for our customers.ย 

  • We rely on FIFO inventory control to avoid stocking complications in the time of need.
  • Our workers follow the guidelines of component labeling to avoid confusion and mishandling. 
  • We stock strategically to prevent PCB wastage. 
  • We make sure to completely dispose of the PCB waste with less harmful techniques to prevent compromising environmental damage.
  • Our solder pastes are cooled in separate cold storage through proper and consistent monitoring and sustenance. 

Extend the PCB Shelf Life in Storage

We cannot forget the fact that PCBA storage is an important factor in the well-being of industrial PCBs. Due to this reason, for the extension of PCB shelf life, we need to avoid mishandling PCBs on all counts. Also, protecting them from weather conditions like excess moisture can help in this regard.

Another factor that proves to be handy for this is your choice of PCB producer. There is no point in hiring such a PCB producer who procures good materials for production but lacks in working with the PCB shelf life. Therefore, the quality of a PCB producer matters a lot here. 

What Affects the PCB Shelf Life?

FULL PCB MANUFACTURING Quote

You must know what factors influence the PCB’s shelf life so that you can have a clear idea about what factors are not healthy for your PCBs at all. Below you will find them! Letโ€™s go!

  1. Components. Always adhering to quality components will improve the PCB’s shelf life. At the same time, cheap and low-quality PCB components will just reduce the PCB shelf life through consistent deterioration. Other than this, substandard PCB parts are also a reason behind full PCB failures and poor electronics performance as well. 
  2. Surface finishing. The choice of surface finish for your PCBs also creates an impact on their life length. For instance, HASL has more PCB shelf life as compared to OSP and others. 
  3. Soldering. The type of soldering you are doing for your PCBs also creates its influence on the PCB shelf life, so it will be better that you fully research the soldering types for PCBs and their relationship with the PCB shelf life as well. 
  4. Conformal coatingIt creates a positive impact on PCB shelf life and protects your setups from weather damage, technical complications, and other issues. It is better to rely on a good type of conformal coating to prevent PCB shelf-life challenges. 
  5. Handling. Issues in handling your PCBs can reduce their shelf life because human sweat, dropping off the PCBs, harmful chemicals, low-quality solder pastes, and debris all can damage the PCBs. Experts believe that PCB producers need to devise ways for proper handling of PCBs to keep their shelf life intact as much as possible. 
  6. Shipping conditions. How you’re shipping your PCBs also matters here. Unmonitored and reckless PCB shipment can damage the structure and might also detach the PCB components on their way to your customers and clients. 
  7. Storage environment. The temperature of your PCB storage room can also impact them; therefore, always stock the PCBs in an optimum environment to avoid damage as much as possible. 

Dangers of using expired PCB

1.    Cause oxidation 

Problems in oxidation eventually damage the entire PCB structure. It also does not let you completely solder the PCBs, and gaps are still left during the process. Therefore the components donโ€™t get fully adhered to the boards, and chances are there that they will drop off too. Experts believe that if we use useful and viable PCB surface finish, then this problem can be solved easily. However, one thing important to note here is that these PCB surface finishes come with different PCB shelf life.

Therefore, it will be better to use an appropriate PCB surface finish that will join the parts strongly with the boards, and they will be able to sustain unfavorable conditions as well. 

2.    Absorb moisture

The major problem with expired PCBs is that they interact with moisture, and they can cause electrical failures and short circuits at the same time. It will be just like how popcorn jumps in a pan. Moisture in the PCBs is also a reason for delamination, which is not good for the proper functioning of PCBs. Baking can be a good option to prevent this, but still, we cannot use this method on all types of PCBs.

However, if we use a sufficient amount of OSP, then this can be easily solved. One important tip here is that if you are going to use OSP, then make sure to complete the reflow process as soon as possible, or else if you delay the reflow, it will complicate things for you. 

Conclusion

There is no doubt that PCB shelf life is an important factor in the well-being and improvement of circuit boards. So that they can perform well for our consumer electronics, we hope that we were able to shed light on PCB shelf life for you in this post. We have also discussed some crucial factors that influence the shelf life of PCBs. 

What is an Electric Circuit Diagram and How Does it Work?

Online Circuit Diagram Maker

The electrical circuit can be described as something created whenever electrons flow and then create electricity. Circuits may be defined as any pathway by which electric current flows. Also, whenever electric current passes or flows inside a circuit, different electrical appliances can use them.

What Does Electrical Circuit Diagrams Mean?

Circuit diagram may be described as a graphical description or representation of any electrical circuit. This can also be called wiring diagram, electrical diagram, elementary diagram, and electronics schematics. In circuit diagrams, an electrical circuitโ€™s components can be indicated making use of standard symbols. This represents electrical connections that are found inside the circuit.

You can use these diagrams in the field of construction, designing as well as maintaining electronic and electrical equipment. Different electrical circuits come with a

  • Source of power i.e. battery
  • Resistor or load i.e. light bulbs โ€“ these results due to the completion of the electrical circuits, like stoves, computers, televisions, fans, electric heaters, as well as many other devices and equipment.
  • Conductor for carrying current i.e. copper wire
  • Switch, for example a light switch that is installed on the wall โ€“ the switch may close or open the circuit as well as control electricity flow. Take note: not all the electrical circuits out there come with a switch; although, a large number of them do.

The power source or battery delivers the required energy for ensuring the flow of electrons. This electrons flow, as well as how fast the flow is, is referred to as the current. In batteries, chemical reactions take place, which creates differences in the electrical potential in-between the batteryโ€™s two electrodes. This potential difference, which is referred to as the voltage, helps in providing energy for electrons to move via the circuit. Its unit of measurement is volts.

What is the Significance of the Electric Circuit Diagram?

Electric circuit diagrams can be described as an electrical circuitโ€™s simplified drawing. It makes use of a solid line for showing the wires or conductor that determines the circuitโ€™s path. Symbols are present on this path for representing the different parts of a circuit like the resistors and power source. The diagrams are utilized for designing, constructing, as well as maintaining the electrical circuits. Also, you can use them for calculating the current present in the different parts of a circuit.

What goes on in the light bulb that lights it up? Looking inside a bulbโ€™s filament, you will see a lot of tiny and small charged particles known as electrons that move through the bulbs. While passing through, some of the energy would be transformed in other forms. What ensures the movement of the electrons? What gives energy to them?

The creation of circuit diagrams is to serve as the circuit designโ€™s blueprint. Circuit diagram offers a graphical description of the arrangement of a circuitโ€™s components as well as the wire relationships that form between them. This technician helps in creating the electric circuit diagram to serve as a guideline for the implementation of the circuit designs or for different communication purposes.

What are the Components of the Circuit Diagram?

In this section, we will be listing some of the circuit diagramโ€™s components.

Closed circuit: This permits electron flow in a path from a batteryโ€™s negative terminal to its positive terminal. This circuit is a complete one, and therefore, current will be able to flow through.

Open circuit: This is a circuit whereby the electronsโ€™ path is interrupted or there is an incomplete circuit. As explained above, whenever there is an open switch, the current flow between two terminals is incomplete. This is why current doesnโ€™t flow throughout the circuit and this is why it is an open circuit.

Short circuits: This occurs whenever both terminals i.e. negative and positive terminals are connected to themselves and a high current begins to flow in this case.

Parallel Circuits: For this electric circuit type, it is made up of branched components. This is why current can be further divided and only a part of current will flow through these components.

Series Circuit: For series electric circuits, the flow of current takes place in equal amounts all through every component inside the circuit.

What is a Simple Electric Circuit Diagram Composed of?

Electric circuit diagrams are simple combinations of switches, batteries, or cells, whereby electricity flows into. You can draw a simple electric circuit diagram making use of these components.

  • Battery: This is when cells are combined together. This has the anode, cathode, as well as the electrolyte.
  • Electric cells: Electric cell serve as a current source inside the circuit
  • Electric bulbs: This device glows whenever it receives electric current
  • Ammeter: It is useful in measuring any current that passes a specific point
  • Switch: The switch will permit or stop the current flow inside a circuit
  • Voltmeter: This helps in measuring the voltage present between two points inside a circuit

What are the Applications of an Electric Circuit Diagram?

An electric circuit diagram makes use of symbols in representing the components of a circuit. Also, they will show you ways of connecting a circuit as well as make it function. It is also useful in determining the current present in several parts of a circuit. The circuit diagram will also show resistors which are connected in parallel or inn series. Whenever these resistors are in the series form, current flowing through each resistor would remain the same. Whenever these resistors are in parallel, current passing through every resistor would be different; however, the voltage formed across each of these resistors would be the same.

Circuit diagrams are useful for circuit design, PCB layout construction, as well as for maintaining the electronic and electrical equipment.

Parallel and Series Circuits

A wireless anti-theft alarm circuit diagram
A wireless anti-theft alarm circuit diagram

Circuits come in two main types; these include parallel circuits and series circuits. Both the parallel and series circuits may have many resistors as well as other features present.

Series Electrical Circuits

For the series circuit, just one path is available for electricity to follow. These resistors are all in a series pattern, and all inside a chain along the circuitโ€™s path. The quantity of current that passes through every resistor is similar to that inside the series circuit. In addition, with series circuits, electricity goes to either nothing or to everything. It isnโ€™t possible for part of these series to receive electricity while the others are not.

Parallel Electrical Circuits

Parallel circuits feature different branches whereby electricity would be able to flow. This is beneficial because when one of the circuitโ€™s branches breaks, then the other branches will keep working.

Electricity would keep flowing along the remaining branches, despite the problems which might occur in a section. You can set up household appliances using parallel circuits. When one appliance in your kitchen stops functioning, then it will not cause the remaining appliances to stop functioning as well.

What Does a Signal Tracer Schematic Mean?

signal tracer schematic

Signal tracing deals with a way of diagnosing where there’s a fault in any audio system. It isn’t as great as the oscilloscope; however it is a less-expensive alternative which could be very useful in different scenarios.

The idea here is that a signal is applied to what is not working, and then the signal is traced through a circuit till this audio disappears. Also, it isn’t useful in power amplifier stages that are directly coupled. This is due to the fact that when there’s one fault in a part of a circuit, this could lead the whole amplifier not to function anymore.

What Does a Signal Tracer Mean?

Signal tracers can be described as amplifiers which could detect RF and audio signals and then play it through the in-built speaker. When you trace signals for each stage via the radio then you will discover the problems causing it to play poorly or not play at all. Whenever you know the radio parts that are functioning properly then you may concentrate on the suspect components and stages.

For instance, whenever you hear the local radio stations via the signal tracer that is connected onto the volume control ‘s center tap, and then sound is absent from the speaker of the radio, then you’ll know that the tuning circuits, antenna, detector, and IF section are all functioning properly. Then you can focus all your attention on the earphone jack, speaker, audio circuitry.

As seen in working radios, you would have the ability of tracing forward via the signal tracer strength and then hear the station of the radio at the outputs and inputs of it’s IF amplifiers and then to the input of the audio amplifier.

Also, the signal tracers meant for circuit and service design work are packaged to take lots of forms with time from the multi-purpose large bench equipment to shirt pocket tracers having a Pen’s shape.

Majority of the signal tracers utilized for all service work during the 1930s made use of vacuum tubes and were known to take up so much space.

What are the Functions of the Signal Tracer?

The signal tracers are utilized for the trouble shooting of any misbehaving receivers. Also, signal generators are useful for troubleshooting and adjusting receivers.

The utilization of signal generators for the adjustment of receivers deserves personal presentation. The author has been able to create a document for the adjustment of receivers. This presentation will cover just the troubleshooting.

Whether you are making use of a signal generator or signal tracer for your troubleshooting, you will have the same goal. This is the isolation of faults to one receiver stage. Practically speaking, this has to do with isolating the malfunction to those components linked to a single unit or tube inside a tube. Immediately you can identify any faulty stage, the activity of troubleshooting changes it’s style to locate one defective component that usually needs  different equipment.

Furthermore, whatever equipment you decide to work with, make sure that you work with a reliable safety practice. This indicates making use of the line isolation transformer, a DC blocking capacitor on the test leads of the signal generator, as well as keeping one hand behind when probing the circuits with high voltage.

 Several signal tracers give access to its output speakers and transformers to serve as a temporary substitute. This could be very helpful when there is no speaker because it is sent for repair or it is not just convenient for use like in the console radio.

Several signal tracers have a NOISE mode that applies a limited voltage which is around 50 VDC into the probe. Also, the author found this important for the repair of any shorted tuning condenser. You can remove this tuning condenser out of the chassis and then apply the signal tracerโ€™s voltage into it, inside the darkened room. In addition, as you rotate this tuning condenser, sparks will show up the contact points between the vanes.

What Does Signal Tracer Schematic Mean?

Signal  Schematic
Signal Schematic

Signal tracer schematics, which is also called schematic diagram, represents the signal tracer elements making use of graphic, abstract symbols instead of using realistic pictures. Usually, this schematic omits all the details, which arenโ€™t relevant to whatever information this schematic should convey, and might add some unrealistic elements which helps in comprehension. For electronic circuit diagrams, the symbolsโ€™ layout might not look like the circuitโ€™s layout.

Furthermore, during the creation of the signal tracer schematic, it is very important that you ensure youโ€™re illustrating the circuit with the appropriate abstraction level.  Also, if you are only making efforts to convey a high-level concept, then the napkin schematic may fail to do this truck. This is why of you have to create a specific schematic for simulation, then you have to be clear regarding the signal sources, power sup[p[lies, component values, and more.

Using the Signal Tracer Schematic

Take for example that you are beginning with a fully dead channel 6506 radio. Now, if youโ€™ll be working with mid-century transistor radios, then you have a great chance one of the quick fixes will be able to start playing again. You should try this before any signal tracing or before aligning a radio.

Next, connect this radio to bench power supplies that have been regulated, which youโ€™ve set to the right polarity and voltage, or just load it using fresh batteries.

Bring your ear near the speaker of the radio like you can. Then switch on the radio. Did you get a pop or click sound from your speaker? If you donโ€™t hear a silent click coming from the speaker of the radio whenever the radio is switched on, then make use of the voltmeter just to be sure power is getting inside the board. Broken speaker wires or battery, bad battery contact, broken PCB trace, as well as power switches that are faulty are well-known problems which may halt your progress.

Also, if you would be making use of a bench supply in addition to an ammeter, check if the drawn current falls within the stated range. Next, connect the ground lead of the signal tracer to the ground of the radio. Determining the ground point from the schematics is easy.

Set your signal tracer into the audio input and when the tracer comes with volume control, then set it mid-way. In addition, place your input-probe on the radio volume controlโ€™s center contact. Then pay close attention to the speaker of the tracer for signals. Then adjust the volume control of the tracer where necessary.

More on How to Use the Signal Tracer Schematic

 If you are lucky you will hear an atmospheric static, as well as local radio stations whenever you tune anyone in. When you listen to any local station, it means that the tuning circuitry, antenna, IF detector and antenna, mixer/oscillator, are all functioning properly. At this point, you will not be able to know if any of these stages are working effectively and efficiently. Also, this tells you thereโ€™s a problem with the audio stage.

Now, things you should suspect include damaged traces, electrolytic capacitors, dirty or clogged volume controls, faulty and out-of-spec transistors, speakers, transformers, etc.

Immediately the problem with the audio has been solved, determining if the performance as a whole is acceptable. Also, check if the audio is undistorted and loud? Can stations be received at the broadcast bandโ€™s low and high ends? Is there a reasonably accurate dial pointer? If you can answer yes to all these, then you are set.

If this isnโ€™t the case, re-trace the signal listening for any increase in the levels of a signal from one stage to the other. Whenever a faulty stage is suspected, compare the measurements with all those that have been listed in service docs in order to isolate the issue further.

Signal Injecting and Tracing Tips

FULL PCB MANUFACTURING Quote

Familiarize yourself with signal tracing on a known-good radio so as to calibrate the test gear as well as yourself. This way is a great one to help you understand the right settings to make use of as well as how the sound of a normal set is, whenever it is traced.

Old PCBs feature a protective coating on them which helps in the prevention of test probes from creating the right electrical contact. Make use of probes having pinpoint tips.

Whenever you hear any rushing static sound when the radio is turned on, and have the ability to control this noise using its volume control, then the section for the audio is fine. Next, you check the IF as well as other sections on the left hand side of the signal tracer schematic.

Conclusion

Understanding and using the signal tracer schematic is very important. Signal tracer schematics, which is also called schematic diagram, represents the signal tracer elements making use of graphic, abstract symbols instead of using realistic pictures. Furthermore, during the creation of the signal tracer schematic, it is very important that you ensure youโ€™re illustrating the circuit with the appropriate abstraction level.

What is a Transistor Circuit Diagram and How Does it Work?

Transistor Circuit Diagram

The transistor forms the main electronic component in all transistor circuits. You can obtain the electronic components in discrete form. Also, they could be integrated within an IC.

The manufacturing of these transistors come in different formats and they could be obtained so as to achieve different roles including small and high power as well as switching, RF, and audio.

What Does a Transistor Circuit Diagram Mean?

Transistor circuits are usually found at the center of the electronic circuitsโ€™ designs of today. Though integrated circuits are useful for so many circuits, the usefulness of the transistor circuit diagram in different areas cannot be overemphasized.

Though making use of discrete electronic components having transistors makes use of more components, tailoring the circuit to offer the required functionality is possible. Accordingly, circuits that make use of discrete transistors as well as more electrical components still form the core of electronic circuit designs.

What this means is that, having a good understanding of the transistor circuit diagram is very important because it would both allow the design of the main transistor circuits, and provide better understanding when operating integrated circuits based on the bipolar transistor technologies.

What are Transistors?

transistors

Transistors can be described as a semiconductor device, which is useful for the conduction and insulation of voltage or electric current. Basically, the transistor serves as an amplifier and a switch. Explained in simple terms, the transistor serves as a miniature device, which is useful in controlling or regulating the electronic signal flow.

Furthermore, transistors form a major component in the majority of electronic devices present today. Developed by three Physicists from America, William Shockley, Walter Brattain, and John Bardeen in 1947, this transistor is viewed among the most significant inventions in scienceโ€™s history.

Typical transistors are made of three main semiconductor material layers or terminals that aid in connecting to the external circuits as well as carry the current. The current or voltage that is applied to any of the pairs of a transistorโ€™s terminals helps in controlling the current via other terminal pairs. A transistor comes with three terminals. These include:

  • Emitter: which is the transistorโ€™s negative lead
  • Collector: Which is the transistorโ€™s positive lead
  • Base: This helps in activating the transistor

Transistor Types

Transistors come in two major types and these are based on the way they are utilized in circuits. Letโ€™s consider them.

Bipolar Junction Transistors

Bipolar junction transistors feature three terminals. These include collector, emitter, and base. An extremely small quantity of current passing in-between the emitter and the base can control the larger current flow in-between the emitter terminal and collector.

Field Effect Transistors

For the field effect transistors, there are three terminals, which are Drain, Source, and Gate. The gate terminalโ€™s voltage can control the current found between the drain and the source. Field effect transistors are unipolar transistors whereby P-channel FETs or N-channel FETs are utilized for conduction purposes. Their applications include analogue switches, buffer amplifiers, low noise amplifiers.

How Does a Transistor Work?

Transistors serve as a gate or switch for an electronic signal, opening as well as closing of an electronic gate as many times every second. It makes sure that the circuit stays on whenever there is a flow of current and then switches off whenever it isnโ€™t.

In addition, transistors are utilized in different complex switching circuits which are made up of all the telecommunication systems of today. Also, circuits provide extremely high switching speeds like at least hundreds gigahertz than the 100 billion on and off cycles every second.

Furthermore, you can combine transistors to form logic gates, which helps in the comparison of many input currents so as to offer different outputs. Computers having logic gates have the ability to make easy decisions making use of Boolean algebra. The techniques form the basis of today’s computer and computing programs.

Also, transistors play a significant role in the amplification of electronic signals. Take for instance, in the radio applications, such as FM receiver, whereby the electric signal received might be weak as a result of disturbances, the amplification becomes necessary to deliver audible output. In addition, these transistors offer the amplification through increase of the strength of the signal.

Design Parameters of the Transistor Circuit Diagram

Before you handle the circuit design of transistor circuits, defining the circuitโ€™s requirements is necessary. Some important parameters linked to the transistor circuit diagram include.

Voltage gain

This is usually a major requirement for electronic circuit designs. The circuitโ€™s voltage gain is a voltage increase from the circuitโ€™s input into its output. Explaining mathematically, the gain in voltage is the quotient between the output voltage and input voltage. Also, voltage gain can be viewed as one of the main purposes of many circuits. This is because it helps to enable the size.

Current Gain

A circuit’s current gain is also important, most especially whenever the circuit will be driving a load with low impedance. Usually circuits without any voltage gain and just current gain are required to enable relatively-high impedance output circuits to drive a second circuit, which has lower impedance.

So many examples are applicable here. RF oscillators usually require the buffer stage so as to make sure that oscillator circuits are not unduly loaded, however the output is required to help in deriving the remaining circuits. The gain in current is also utilized in the power supply circuit whereby the voltage regulatorโ€™s series pass elements have to provide high current levels, however making use of the low voltage current reference. Other examples whereby current gain is necessary and required.

Just like the voltage gain, a circuit’s current gain draws a comparison between both the output and input levels. However, this happens in terms of the current. Furthermore, current gain equals the output current and then divided by input current.

The Input Impedance

A transistor circuitโ€™s input impedance always plays a significant role. It helps in the determination of the loading on the initial stage. Also, it is important for RF circuits whereby the impedance matching is a very important parameter.

For many designs of electric circuits, high input impedance is usually desirable because the initial stage won’t be unduly loaded. If the transistor circuitโ€™s input impedance is extremely low, then the initial one would be loaded. This then reduces the level of signal and thereby causes some distortion in some scenarios. In addition, the configuration of the transistor stage in providing the appropriate input impedance forms a major element of the process of electronic circuit designs.

Design Process of the Transistor Circuit Diagram

There are different stages involved in the design process of the transistor circuit diagram. They are taken in the logical order, however there are some revisiting of these stages in order to optimize the electronic componentsโ€™ values in order to offer the overall performance required.

Determine the requirements

A very important phase is to determine the real requirements, as well as getting it correctly would mean that the circuitโ€™s concept will not change later on.

Determine the topology and function of the circuit

Immediately we have settled the requirements for the full electronics device, it becomes important to decide on the actual transistor circuits. For instance, many oscillator amplifiers, circuits are available for the transistors and it is possible to choose the best type for that specific requirement. Also, this defines the true circuit topology.

For example, the utilization of common base, common collector, common emitter, but if it isnโ€™t, it could be a part of the general decision making during this period. This is because the loading on the output impedance, gain, oscillators, and others could be considered during this period.

Setting up the bias conditions

For all circuits, one important feature of an electronic circuit design involves ensuring the labels of bias for all active devices. For this reason, the bipolar transistors could be correctly set. If thereโ€™s an incorrect bias, this transistor circuit wouldnโ€™t function.

The determination of the electronic componentsโ€™ value (majorly the resistors), which sets the bias is one important stage of the transistor circuit diagram design.

Determining the values of the functional electronic components

Coupled with setting the conditions of the bias, other values of the electronic components to offer the appropriate circuit functionality has to be determined. This phase of transistor circuit diagram design will proceed with the setting of the bias conditions, as one value will have an effect on the other value.

Conclusion

 It is clear that the main electronic component in all transistor circuits is the transistor. You can obtain these components discretely or they might be within the integrated circuits.

What is the Significance of Battery Circuit Diagram?

Battery Circuit Diagram

The battery is an important part of a Circuit. It is one of the best and most common sources of power for many devices. From handheld devices to high performance industrial machines, batteries are commonly used. The battery circuit diagram explains a lot about the function of batteries in a circuit.

Here, we will shed more light on battery Circuit diagrams, their function, and what they are made of. Also, we will look at how battery circuit diagrams are created. At the end of this article, you would have a vivid understanding of the function of batteries in a circuit diagram.

What is a Battery?

A battery comprises electrochemical cell(s) that can easily convert chemical energy into electrical energy. It is a core part of a circuit. There are three main parts of batteries and these are the electrolyte, cathode, and an anode.

For all batteries, chemical reactions come into play which produces the anodeโ€™s electrons. This is what differentiates the anode from the cathode. These differences have to be taken away from the picture and this is why electrons rearrange.

Moreover, electrons will be able to achieve this using a specific way. These electrons get transported to another location having fewer electrons called the cathode.

Furthermore, electrolytes stop electrons from moving directly between the cathode and anode. A wire exists that links both the cathode and anode.

What is a Battery Circuit Diagram?

Battery Circuit Diagrams
Battery Circuit Diagrams

Battery circuit diagrams can be described as a visual representation, which aids in the simplification of the batteriesโ€™ functions inside the electrical circuits.

This is a very important tool that helps in the creation and maintenance of electronic equipment. A battery circuit diagram utilizes symbols, images for presenting a batteryโ€™s elements as well as the way they are linked and connected.

It helps in presenting a connection between the electrolyte and the electrodes (the cathode and the anode). Battery circuit diagrams are important for the design of electrical circuits. Also, it describes the way battery fits inside the electrical circuits. It aids engineers as well as technicians to comprehend the batteryโ€™s position better as well as how they function in the circuit.

For electrical circuits, battery gives energy by charge movement from the low to the high energy terminals. Whenever the charge gets moved to a higher energy, differences in electric ability across the external circuitโ€™s ends will be created. Charge will end up passing through this external circuit.

So many people feel battery serves to create charges that flow through the circuit. Also, they have this belief that batteries cannot function anymore when it loses charge. This is false; because you can charge batteries and make them work again. Batteries re-energize themselves by reversing its chemical reactions which take place on the inside.

What Does a Circuit Diagram Consist?

Batteries form a very important component in electric circuits. Moreover, this isnโ€™t the only part of a circuit; however there are some other components which make up the circuit. Now, let us consider some of these symbols to help us understand this section better.

Switch

A switchโ€™s symbol is denoted by a line having a gap or break. This gap closes whenever you close or turn the switch on. When you switch off or open the switch, a gap exits, which indicates that there is a disruption in current flow

Electrical cell

This is a long and short parallel line that represents electric cells. The short and long line represents the positive and negative terminals respectively.

Battery

There are multiple electric cells in a battery and these cells are linked together. Electric cell symbols usually represent a battery.

How do Batteries Work?

The anode and the cathode are the two ends in a battery circuit. While the anode represents the negative terminal, the cathode is the positive terminal. A circuit forms when these two terminals are connected with wire. Furthermore, there is a current of electricity once the electrons pass through the wire. There is a lot of work going on inside the battery as chemicals react. However, chemicals can only react when electrons flow.

You can store a battery for a while and expect it to work since the chemical process can only occur when there is flow of electrons from negative terminals to positive terminals. A battery contains cells which go through some reactions, mostly chemical, to generate the flow of electrons in a circuit. The battery circuit became important due to the need to store the energy you generated.

There is a build up of electrons at the anode when you connect batteries. This causes a difference between two electrodes. As a result of this, the electrons redistribute themselves, but the electrolyte prevents this from happening. This offers a clear path for electron flow between the anode and cathode.

What does a Battery Contain?

You can easily understand the working principles of a battery when you know what it contains. There are several elements that make up a battery.

Container: A battery has an empty steel as its container. This container comprises all other elements of a battery.

Separator: This is a kind of paper that prevents the cathode from having any form of contact with the anode.

Cathode mix: This powder is a combination of manganese dioxide and conductors with the presence of electrical charge. The cathode mix is usually attached to the inner wall of an empty container.

Collector: The negative current collector contains a brass pin which you insert in the battery. This pin is always capped and sealed.

Anode: One of the most crucial parts of the battery circuit is the anode. The anode has a negative charge and potassium hydroxide electrolyte which pumps into the container.

What is the Role of a Battery in a Circuit?

A battery plays a significant role in how a circuit works. It converts the chemical energy it stores into electricity. The working principle of a battery in a circuit is based on an electrochemical cell. There are several electrochemical cells in a battery. Every electrochemical cell comprises two electrodes. An electrolyte separates these electrodes.

The question is how do electrochemical cells produce electricity? We can only know the answer to this question when we understand what electricity is all about. Electricity is said to be generated through the flow of electrons. A chemical reaction which occurs at an electrode produces electrons in an electrochemical cell. These electrons then flow to another electrode.

For a free flow of electrons, there is a place where electrons would come from and where the electrons will as well go. These are the electrodes of the cell. Also, there is the flow of electrons from the anode to cathode. There are several chemical reactions occurring in a battery. The electrode always responds with the electrolyte in such a way that electrons are produced. On the other hand, there is a chemical reaction which happens simultaneously. This reaction allows the electrode to receive electrons.

What are the Types of Batteries?

There are various categories of batteries. They can be classified based on their applications, form factor, size, and composition. However, the two major types of batteries are secondary and primary batteries.

Secondary batteries

The chemical reactions of these batteriesโ€™ electrochemical cells can be reversed. This can be achieved by using a particular voltage with the battery. Secondary batteries are also rechargeable batteries since it is possible to recharge secondary cells after you have used up the battery. Also, these batteries are ideal for use in high drain applications. You can as well use them when single charge batteries are too expensive to use.

Electronic devices such as phones can be powered by small capacity secondary batteries. Heavy-duty batteries can power electric vehicles. Also, these batteries are applicable when load leveling electricity generation.

Alongside inverters, secondary batteries can serve as standalone power sources to supply electricity. According to their chemistry, there are different types of secondary batteries.

Primary batteries

It is impossible to recharge primary batteries once they have been used. These batteries comprise electrochemical cells. In such batteries, you can reverse the electrochemical reaction of the cells. There are several types of primary batteries and they range from AA batteries and coin cells. For standalone applications where there is no need for charging, primary batteries are a great choice.

For instance, primary batteries are applicable in military grade devices because soldiers on the field can forget to charge batteries. Furthermore, primary batteries are designed to consume very low power which helps them last longer. Other applications where primary batteries are useful include remote controls, animal trackers, wrist watches, pace makers, and more. Alkaline batteries are one of the most common primary batteries.

Conclusion

The battery circuit diagram is created to know the function of a battery in a circuit. This diagram is useful for creating electronics.  It shows the relationship between the cathode, anode, and electrolyte.  These components are very important and as such you need to study their interconnectedness.

Top Comparison between IGBT vs. MOSFET

IGBT vs. MOSFET

The progress in the field of technology has made it possible for us to use a vast range of transistors. Different consumer electronics that we use today comprise such transistors. From basic to highly advanced transistors, consumer electronics come with these exceptional components. Now each type of translator differs from the other. There are different factors that distinguish these types for our own ease.

So that choosing the right transistor for you will become a lot easier. But keep in mind, with perks come downsides of these transistors as well. In this post today, we are going to compare IGBT vs. MOSFET transistors. So that you can learn to use these special types as per your needs. Here we go!

Well, both these types are common in consumer switching devices and electronics. The reason is that there are certain features and specifications that set these transistors apart from the others. From solar inverters to motor driver systems, these transistors are simply exceptional in performance and provide you with desired results as well.

Now it’s time to learn about these transistors individually so that you can develop a better understanding of IGBT vs. MOSFET transistors through further sections.ย 

What is MOSFET?

SMD MOSFET

First, we have MOSFET, which is a low-voltage transistor and is a lot different from other types like BJT. BJTs are mostly currently controlled, and therefore, their specifications are also different. The features of MOSFET include low current and high voltage, and due to this reason, you can easily use it to your own needs and advantage. There are three important points present in MOSFET.

One is the drain, the other is the source, and the last one is the gate. You can use a MOSFET through its different modes called depletion and enhancement. The two main categories of MOSFETs include one with N-channel and the other with P-channel. The voltage present on the gate actually creates a fine line of difference between different types of MOSFETs.

When you are using the depletion mode, keep in mind that the conductance will be at its highest. While in the other case, there will be zero voltage at the gate. When you are using the enhancement mode, it is obvious that the conduction will only take place when the voltage is higher. There is another important thing to note that when you increase the positive voltage as compared to the default voltage, then the electrons present in the source and the gate will develop a conduction layer.

It means this is the condition for the conduction layer to be developed. In most cases, this layer takes place between the P-channel and the oxide layer. As the voltage increases, it will cause more flow of current towards the drain. So this is how you will turn on the conduction mode of a MOSFET by using voltage.

What is IGBT?

IGBT is nothing but a combination of a MOSFET and a BJT. The nature of an IGBT is monolithic. Therefore this is how you will get double the features and advantages of transistors in a single IGBT. IGBT is important to consider here because these take the exceptional current controlling ability of BJTs and easy usage of MOSFETs. Due to this reason, different users rely on IGBTs for the incorporation of different consumer electronics.

You can easily use an IGBT if you are aiming for a medium-power application. For a high-power application, you must consider some guidelines to derive desired results. Just like a MOSFET, you will have three important terminals in an IGBT too. These are a gate, a collector, and an emitter. The purpose of the gate is to control the transistor, while the conductor and emitter are for seamless conduction. The overall channel structure of an IGBT is P-N-P-N which sets it apart from the rest of the transistors. In the case of bias, the P-base will develop an N-channel.

When this happens, the resistance of the N-layer reduces dramatically, and the positive elements go toward the N-layer and leave the player. Due to this reason, it can easily tackle high levels of current. One another impressive factor about IGBTs is that their conduction faces fewer power losses. 

Differences: IGBT vs. MOSFET

1.    Basics: IGBT vs. MOSFET

One major difference between IGBT and MOSFET is their basics. There is no doubt that both these transistors are controlled by voltage and have similar applications in terms of switch mode power supply. However, we need to know that IGBTs are important when we are talking about higher current applications.

Whereas MOSFETs are for providing more feasibility in terms of control. IGBTs can render benefits of a BJT, and a MOSFET but MOSFETs alone cannot render benefits like IGBTs. You can use a MOSFET for voltage determination, but an IGBT will not be able to do this for you at all. 

2.    Working Principle: IGBT Vs. MOSFET

One another thing that separates IGBT and MOSFET is their working phenomenon. When it comes to IGBT, you can easily make changes and control the bipolar side of the transistor.

However, a MOSFET works best for FET, and the element of silicone oxidation is also there to distinguish its working from an IGBT. MOSFETs are more likely to perform naturally because their gateโ€™s voltage keeps changing, and a fine layer of silicone protects this change during the process. Moreover, a MOSFET has two modes of functions while IGBTs donโ€™t. 

3.    Input Impedance: IGBT vs. MOSFET

Sometimes you can also understand IGBT vs. MOSFET through input impedance. When we talk about IGBTs, you can expect more input impedance as compared to MOSFETs. IGBTs, therefore, are a better option to opt for when it comes to using them for high-current applications. The problem with MOSFETs is that they struggle with the voltage at the gate, and due to this reason, they are not reliable for current-oriented applications.

However, MOSFETs come in handy when you are considering protection in terms of current leakage and voltage blocks because the silicone layer will prevent this from happening on all counts. 

4.    Damage Resistance: IGBT vs. MOSFET

Both the transistors are also different in terms of damage resistance. MOSFETs can easily tolerate changes in the charges and more input impedance. Due to this reason, you cannot use MOSFETs for damage resistance between extremely low capacitance makes them a bit difficult to prevent damage.

Other than this IGBTs can prove to be more beneficial because of the double benefits of a MOSFET and BJT. So no matter how much intense was the voltage change, an IGBT can impressively tackle it for you. 

5.    Applications: IGBT vs. MOSFET

Another huge difference between IGBTs and MOSFETs is their applications. Now this is obvious that you cannot use an IGBT for a MOSFET application. MOSFETs are more reliable for the changing of signals and amplification of different electronics.

These mostly come in handy for the high noise devices. You can make use of a MOSFET in different types of analog and digital circuits since this cause no harm to their functioning at all.

IGBTs have different applications than MOSFETs because they are more likely to control the current. Therefore applications including induction, heating mechanisms, and motor control are all possible with IGBTs.ย 

6.    Switching power: IGBT vs. MOSFET

The switching power of both is also different. This term means how much power a transistor is to switch between on and off situations. Sometimes you can even call switching power dissipation as well.

MOSFETs are incredible in terms of switching power as compared to IGBTs. Therefore if you want to use a transistor for higher switching power, then using a MOSFET will save you from disappointment. 

7.    Voltage & Current: IGBT vs. MOSFET

In terms of voltage and current, both these transistors are different. However, IGBT is more reliable for the current and voltage capacity, and you can use it easily for similar applications. MOSFETs are not reliable for this purpose because they cannot deal with transient voltage as IGBTs do. 

8.    Structure & design: IGBT Vs. MOSFET

To quickly differentiate between these two transistors then, take a look at their design and structure. But one problem that stands here is that they have the same design. It is difficult to identify them at a glance.

However, if you are an expert, it won’t be difficult for you whatsoever. There are more P layers in IGBTs present under the n substrate. MOSFETs donโ€™t have a structure like this, and due to this reason, MOSFETs can easily handle quick switching when you are using them for higher frequencies.

IGBTs do have a PN junction, but it remains concealed in their structure. For MOSFETS, they donโ€™t have a PN junctional at all. Now from this difference, you can easily learn how you can distinguish IGBT vs. MOSFETs so that using them according to your needs and future projects will become easier for you.ย 

Key Benefits of IGBT

IGBT
IGBT
  1. You can use IGBTs for medium to high-power applications. It is because these transistors can easily conduct high currents and voltages for specific applications. 
  2. IGBTs can easily perform under stressful and unfavorable conditions like high voltage spikes and unprecedented voltage changes. 
  3. The gate insulation of IGBT is much higher as compared to other transistors, and due to this reason, it becomes much easier for the users to rely on them for different projects. 
  4. The forward voltage drop produced by an IGBT is much less as compared to other transistors, and because of this, their performance remains unmatched by other transistors available. 

Drawbacks of IGBT

  1. The IGBT is not a good option when it comes to high-frequency devices because their natural performance can be altered due to their incorporation. 
  2. The switching speed of the IGBT is extremely slow, which can complicate the functioning of the devices; therefore, in this case, you can still look for different alternatives. 

Benefits of MOSFET

  1. Unlike IGBTs, a MOSFET can easily tackle complications and sustain its performance for high-frequency applications. 
  2. The switching speed of a MOSFET is also incredibly higher than other types available. 
  3. It is good for controlling and reducing noise signals, and due to this reason, using it for such applications renders desired and positive results. 
  4. It is compact in size, and therefore using it for complex applications is a lot easier.
  5. MOSFETs are overall less expensive, and therefore, almost all producers can rely on them for their projects easily. 

Drawbacks of MOSFET

  1. It can collapse in case you are giving it more voltage, power, and current. 
  2. Unlike high voltage raise, its performance can be dramatically changed. 
  3. The forward voltage drop of a MOSFET is much higher as compared to IGBT, and therefore, this makes it not a good choice to use in different applications. 

Can I use IGBT instead of MOSFET?

Yes, you can do this. However, there are some considerations that will help you in this regard. IGBTs are more reliable for high-power devices because the overall power loss given through IGBTs are much less. Therefore experts consider these more efficient instead of other types. MOSFETs are more reliable for low-power devices because their switching speed is higher than IGBTs. 

Wrap Up on IGBT vs. MOSFET

Both IGBTs and MOSFETs have their own advantages. These are also different from each other in some areas, and due to this reason, it is important that you choose the right transistor for your projects.

We have described IGBT vs. MOSFET in detail in this post so that you can easily understand what factors make them different from each other. Plus, how you can make full use of them by implementing them according to their nature and features.
