Top Things to Know about PCB Board Thickness Tolerance

1.0mm PCB thickness

In the starting pages of the Institute for printed circuits (IPC) standard for PCB, a reference table (1-2) is provided, which is referred to as Default Requirements. While reading these guidelines, one may consider them questionable. There isn’t sufficient information from a manufacturing point of view, but enough information is there to quote.

Probably there would have been some set standard for manufacturing guidelines to build these circuit boards with all the available information to meet the process. 

But Is that sufficient? Let’s dive into this article to get some awareness about important points that you should know. 

Understanding PCB Board Thickness Tolerance

The definite Tg rating (transition of glass) for PCB laminate materials is usually rated as FR4, 170Tg, and 180Tg, respectively. When brands list the material as basic Tg and do not provide specific information, they allow the production of stock in common material. An In-depth review is needed when a stack-up of specific dielectrics is provided. Stating the exact PCB thickness is crucial in the production and selection of the material that is being used. 

If the tolerance of the required product is less than 10%, it will push the quote to engineering review and delay the process. Take an example of a 6-layer PCB that will require 0.014″ cores to be used and meet the thickness of 0.062″. This can be achieved, but the remaining building material will be left in assumptions and falls within the thickness of +/-0.0062″ in total. Thickness of the completed parts will be 0.056″ – 0.068″, and there can also be a variation between these values. It’s not possible to meet the exact value, and tolerance is always required.ย

Standard PCB Board Thickness Tolerance

The standard base thickness of MCL is 0.062″ or 1/16″, which has a 10% tolerance. This thickness of PCB is very common and considered to be the industry standard because 1/16″ was the size of Bakelite sheets that were manufactured back in the days of PCB fabrication. Although this thickness is considered very common, many other thicknesses are also seen in PCB manufacturing. Other than 0.062″ boards, there are also 0.031″ and 0.093″ boards that are used commonly, and they meet the needs of more firm and multi-layer boards. These thicknesses of boards are considered to be the most common, although they can have other thicknesses as well, which can be within or outside of this range. 

Factors That Impact PCB Board Thickness Tolerance

On the one hand, it is very crucial to know the industry standard thicknesses, but on the other hand, there are many other factors that are important to consider for a custom board. There are two main groups of factors that can impact the thickness of PCB; Manufacturing factors and Design factors. Depending on these manufacturing factors and designs, your board may need to have a non-standard thickness. Letโ€™s further explore these factors in detail and guide you on how to choose a suitable PCB thickness for your next project. 

Design Factors That Impact PCB Board Thickness Tolerance

Design factors are taken into consideration when the PCB is in the designing phase. Instead of practical considerations, these factors rely on the purpose and functionality of the board, although manufacturing factors are equally important. The most crucial design factors which impact the thickness of PCB are as follows:

1. Size, Weight, & Flexibility

Thinner boards are comparatively much lighter and a bit more flexible than thicker ones, but they are brittle and can break more easily. Flex PCBs should be thin to gain their flexibility, but other applications that don’t require to be flexible can benefit from thicker boards for their structural integrity. Although thicker boards are rugged, they are heavier and consume more space in a device. These features are problematic for devices that have limited space capacity and lightweight apps. These factors are identified when PCB is in the final application, and these factors should be checked and defined before designing PCB. 

2. Copper Thickness

The thickness of the copper layer plays an important role in overall PCB thickness because it determines the amount of current that passes through the PCB. The standard thickness of copper is usually around 1.4-2.8 mils (1-2 oz), but this thickness can be adjusted accordingly for the specific requirements of each board. If copper is thicker, the boardโ€™s thickness will also increase, and so will the price because of the material that is needed and processing challenges.

3. Board Materials

The choice of materials used for the production of PCB can affect its lifetime and operations. It can also have an impact on the thickness of the board. A simple board fabrication consists of the laminate, substrate, silkscreen, and solder mask.

The most important ones are the laminate and the substrate because they have a great impact on the overall thickness and structure of the board. Laminates consist of thermoset resin and either cloth layers or paper. On the other hand, the substrate consists of epoxy resin and paper, ceramic or glass weave depending upon the required dielectric constant.ย

4. The Number of PCB Layers

FULL PCB MANUFACTURING Quote

Undoubtedly, the thickness of the board is influenced by the number of layers of PCB. The standard threshold of PCBs thickness falls between 2-6 layers but not more than eight layers. Manufacturers may use thinner layers of PCB to meet the standard thickness, but it is totally impractical as the layers increase in number.

If the design needs extra layers, then allow the increase in thickness of the PCB. If your design doesnโ€™t need those multiple layers and requires to meet certain parameters of thickness, then reduce the number of layers. 

5. Signal Types

There is a vast range of signal types that PCBs carry, which helps in identifying the materials that are required for the board and can also affect the thickness of the board. For example, if there is a board carrying high-power signals, it will require wider traces and thicker copper, which significantly makes it thicker than the boards that are operating with low-power signals. However, high-density boards having complex signals use thin traces, lasers, and thin high-performance materials, which makes them thinner than other types of boards.

Conclusion

Concluding this article on a note that using the right size, base material, number of layers, types of signals, and thickness tolerances for the plated and non-plated features plays a crucial role in determining the impact on PCB thickness. There’s always a need for PCB tolerances to make sure that the products are being properly used and processed.

PCB Assembly Cost Calculator

The PCB cost calculator starts working the moment the manufacturer begins information analysis. The professionals will enter the necessary data and wait for the calculator to provide a response. The amount so acquired is dependent on a number of important factors that may need to be changed if the actual cost turns out to be higher than anticipated.

To make modifications simple, once the calculator offers a number, it is essential to understand the price before assembly, particularly the cost of the material.

ยท Material Cost Before Assembly

The manufacturing business begins by obtaining bids for the electronic components and PCB bare boards, along with estimates for designing and PCB assembly charges to be added to the purchase amount. Because of capacitance disk loading, Surface-Mounted Technique chip, and resistance, the resulting must replace around 5% of the destroyed material. But the prices are offered with modifying SMT line, stencil, and processing file for lesser PCBA quantities.

ยท Solder Joint Cost

As every solder junction on a circuit board is unique and requires a separate processing procedure, SMT and DIP after welding are other important factors to take into account when estimating the cost of PCB assembly. A single solder pad is typically considered as one point, whereas the length of an IC solder junction is measured in feet. After 1206 SMD accuracy, with the exception of CD54 inductance, which is recorded to 12 points rather than the other solder pads’ 24 points, each solder pad is given two points.

The price ranges between 0.03 CNY and 0.008 CNY depending on the kind and other variables after accounting for every solder joint. The test time of the PCBA board, which covers packing logistics, the price of three proofing paint, and special packaging materials, is the next assessing factor. Moreover, the term FOB which is related to transactions, is also required to be added to the cost calculator of PCB assembly.

Order volume has a major impact on a commodity’s price, which is among the main fundamental principles of economics. A bigger order quantity typically results in lower product pricing.

The assembly of printed circuit boards is also subject to this guideline. For instance, paying $3.025 per unit for ten pieces of a standard 50mm ร— 50mm 2 layers order will cost you $30.25. You will pay $30.15 if you alter your order to 30 units at a price of $1.005 per item. You’ll save a ton of money on manufacturing as a result. For businesses searching for affordable SMT, it’s the ideal solution. As a result, a pick-and-place robot will be able to put the electronic components on the Assembly of PCB with ease.

PCB Assembly Cost Calculator for Single-Sided Or Double-Sided

The total cost of a PCB assembly is significantly influenced by the number of panels in the assembly. Every time there is a layer count rise, the price of a PCB typically goes up. In simple words, the price of the PCB increases each time a layer is added to the circuit board.

A double-sided PCB of 50 by 50 mm from several manufacturers costs about $16. It requires online information on purchasing customized PCBs.  

Conclusion

Engineers base their estimate of the cost of PCB assembly on a variety of factors. This occurs because the cost of producing electrical equipment is a very important consideration. The good thing is that you may make effective preparations for a PCB assembly job by making an accurate guess as to how much it will cost. All you have to do is carefully analyze a number of important variables that have an impact on PCB assembly costs.

Your company’s profitability can increase if you can reduce the cost of PCB assembly. Working with the proper PCB manufacturer is a clever method to keep prices low.

The Differences Between Hot Swappable PCB and Solder PCB

hot swappable PCB

A PCB (Printed Circuit Board) that supports hot swapping enables quick removal and replacement of electronic components without shutting down or turning off the machine. As a result, users can quickly replace broken or obsolete parts without affecting the system’s functionality. Hot-swappable PCBs are frequently ideal in fields that need high availability and uptime, like data centers, servers, and industrial control systems. They offer a practical and effective method for maintenance and upgrades without generating downtime, increasing productivity, and lowering costs.

Hot swap Vs. solder PCB

Modern electronics come from printed circuit boards (PCBs), the framework for mounting and connecting electrical components. PCBs come in various forms, with hot-swap and soldered PCBs being two of the most popular. We shall examine the ten primary distinctions between hot-swappable and soldered PCB.

Replacement of Components:

The main distinction between hot-swap and soldered PCBs is the ease with which electrical components can be removed and replaced with hot-swap PCBs without the requirement for desoldering. On the other hand, with soldered PCBs, the components must first be desoldered to be removed and replaced.

Flexibility:

Comparatively speaking, soldered PCBs are less flexible than hot-swappable PCBs. Soldered PCBs need the system to be powered down and cooled before replacing components. However, hot-swap PCBs allow users to change or upgrade components immediately without disrupting the system’s operation.

Cost:

Because they are more flexible and complicated, hot-swap PCBs are typically more expensive than soldered PCBs. In addition, connectors and the hot-swap mechanism require extra parts, which might raise the PCB’s overall cost.

Size:

Due to the additional components needed for the connectors and hot-swap mechanism, hot-swap PCBs are often bigger than soldered PCBs.

Maintenance:

Compared to PCBs that are soldered, hot-swap PCBs require less maintenance. Users can quickly swap out components with hot-swap PCBs without affecting the system’s functionality, reducing maintenance downtime. Contrarily, desoldering components from soldered Boards necessitates additional maintenance and can be time-consuming.

Durability:

Due to the extra parts needed for the connectors and hot-swap mechanism, soldered PCBs are often more durable than hot-swap PCBs. Moreover, soldered PCBs provide a more reliable connection between the components and the PCB, which can lessen the risk of damage and increase the system’s overall toughness.

Customization:

Due to the additional parts needed for the hot-swap mechanism and connectors, hot-swap PCBs can be customized more than soldered PCBs. More customization possibilities may be possible with this added flexibility, which may benefit particular systems or applications.

Application:

Hot-swap PCBs are frequently helpful in sectors including data centers, servers, and industrial control systems that demand high availability and uptime. In addition, electronics that are more geared at consumers, such as laptops and cell phones, frequently use soldered PCBs.

Soldering Electronics Tools

SMT-Through-Hole-Soldering

One of the best things about learning soldering skills is that it is not complex and doesn’t require much from you. There are various soldering tools that help in the soldering process. Some of the most used soldering tools are described below.

ยท Soldering Iron:

Soldering Iron is a manual tool operated by plugging into the power supply of 120V AC. When the current passes through the iron, it heats up and melts the solder. A soldering iron is one of the important and widely used soldering tools. It is available in distinct forms, like a gun or pen, depending upon its usage. For starters, pen form soldering iron is mostly recommended between the range of 15W to 30W. Moreover, some soldering comes with variant tips that can be interchangeable and used for different purposes. A standard soldering iron can warm up to 896 Fahrenheit; therefore, use it carefully while using it. 

ยท Soldering Station:

The soldering station is considered the latest version of the traditional soldering pen. It is a great choice if there are a lot of components to solder. Moreover, its flexible features and controlling features make it an ideal choice. One of the biggest benefits of using a soldering station is that it allows for adjustment of the heat of the iron according to device requirements. Moreover, these soldering stations come with temperature sensors, password settings, and alert settings and give a quite safe space for work.  

ยท Soldering Iron Tips:

The end part of the soldering pen or iron is known as the soldering Tip. Most of the soldering irons come with an interchangeable soldering tip. These tips come in a variety of sizes and shapes depending on their usage. Each Tip is specially designed to offer specific benefits and purposes. The Chisel tip and the Conical Tip are both commonly used tips in almost all electronic projects.

  1. Chisel Tip consists of a broad flat pin which is ideal for soldering larger components or wires. 
  2. Conical Tip consists of a fin tip which is especially used for attaining precision in the soldering process since it has a very pointed tip that ensures the transfer of heat even to smaller spaces without causing any disruption in the surroundings. 

ยท Brass or Conventional Sponge:

Conventional or brass sponge is also one of the most important soldering tools. It helps in cleaning the iron tip of the soldering iron. It ensures the removal of the leftover oxides on the iron tip. Due to oxidation on the iron tip, it gets black and does not accept more solder than it did before. A wet sponge can also be used though it might affect the lifespan of the iron due to contraction and expansion. Moreover, it also drops out the temperature of the soldering iron tip when it is used. Therefore, brass sponges are always a good option. 

ยท Soldering Iron Stand:

A soldering Iron stand is one of the basic tools, and it also gives a handful of benefits. It keeps the hot soldering iron away from the other flammable materials that might get caught fire accidentally when it comes into contact with it. This could also lead to hand injuries. Most of the soldering irons come with a built-in stand and cleaning brass sponge.

The soldier is a mixture of metals that is used to bond electrical components together by melting them. There are both lead-free and lead variations of solder. They also come with different diameters like 0.062โ€ and 0.32โ€. Under the core of the solder, there is a flux named material that supports improving mechanical strength and electrical connection between the components. 

Rosin lead-free core solder is one of the common types of soldering for electronic devices. This solder is basically a mixture of Copper or Tin. It also comes with lead, of which 60% is tin and 40% is lead. But this soldier is losing their fame as it affects health. However, always wash your hands, and do proper ventilation before using lead solder.

Always choose a non-acid core solder because the acid core might damage the components and circuits. Solder with the acid core is commonly sold at house maintenance stores and is widely used for metalworking and plumbing.

Since solder comes in various forms and diameters, the diameter of 0.062โ€ of solder is ideal for soldering bigger joints faster. However, it might not work well with smaller joints. Therefore, make sure to have both soldiers with distinct diameters. 

ยท Helping Hand

The Helping hand is a type of device with two or sometimes more alligator clips. It also contains a magnifying lens in some variations. It helps you in holding the components that you need for soldering while you manage the soldering iron. This is one of the most helpful tools that you should have in your working space.

ยท Soldering Safety

As you already know, what types of soldering tools and devices are used in the soldering process of electronic devices? Here are some practical safety tips that ensure your safety during soldering.

The soldering iron has a temperature limit of over 800โ€™ Fahrenheit which is quite a lot of high. Therefore, it is recommended to use an iron stand that protects from unwanted events of fire and burning.

Always ensure to work in an open space or ventilated space. During the heating process of solder, the alloy releases toxic fumes, which can be dangerous for the lungs and eyes. That is why it is recommended to install a fume extractor. It is a type of fan that contains a charcoal filter that ensures that no harmful toxins are left in the room.

Moreover, always use glasses while working with solder as the hot solder might get a splash on your eyes. 

Last but most importantly, always wash your hands after the soldering process so that there wonโ€™t be a toxin left on your hands.

ยท Tinning The Tip

Before starting the soldering process, the first step is tinning the Tip of the soldering iron with the solder. This supports the transfer of heat faster from the soldering iron to the soldering components. Tinning also ensures the reduction of wear and protects the iron tip. 

  1. First, ensure that the Tip is firmly attached and screwed well in place.
  2. Turn on the power of the soldering iron. Leave it for a few minutes to heat up. If you are using a soldering station, then you can adjust the temperature to 400โ€™C 
  3. Take a cleaning sponge and clean the Tip of the iron with a wet sponge. Left the iron on the stand to warm up again.
  4. Then hold the solder in one hand and the soldering iron in another. Touch the iron tip with the solder and ensure that the solder flows swiftly around the iron tip.

You can also repeat this process after the soldering session too. It enhances the life span of soldering.

How To Solder Electronics? 

1. Mount The Components:

First of all, start with the wires of LEDs. Put them in the drill holes of the printed circuit board. Flip the circuit board and bend the wires on the outer side at an angle of 45โ€™. This helps in creating a better connection of the components with the copper board and protecting it from dropping during the soldering.

2. Heat The Joint:

Turn on the power of the soldering iron and let it heat up. If it has adjustable temperature control, then set the temperature to 400โ€™C. Then touch the iron tip to the resistor lead and the copper pad simultaneously. Put the soldering iron at the exact point for almost 3 to 4 seconds to heat the lead and pad up.

3. Apply Solder To Joint:

Keep holding the soldering iron in the same position as touching copper and lead, and then touch the solder with the joint. An important thing to note here is that you never touch the iron tip directly with the solder. You have to be sure that the joint is heated enough to melt the solder right away. If the joint is cold, then it will create bad connections.

4. Snip The Leads:

Remove the iron from the joint and let it cool down the solder naturally. Donโ€™t blow over the solder to cool it down, as it makes bad connections. Once the solder is cool down, snip the exaggerated wires from the leads. 

A perfect joint is shiny and smooth and gives a cone and volcano shape look. Just put enough solder so that the joint will be covered. Too much solder makes a solder ball which can be spilled over other joints or leads.

Desoldering

One of the good facts about soldering is that it can easily be removed through a process called desoldering. This helps in removing the component as well as making corrections in the soldering process. For the desoldering process, you just need a solder wick, also referred to as a desoldering braid.

  1. Place a small piece of solder wick or desoldering braid over the solder tip you want to remove.

Heat up the soldering iron. Touch the iron tip to braid. This heats up the solder, which will be absorbed by the braid. Remove the desoldering braid and check whether the solder was removed properly or not. Touch the braid carefully, as it still might be hot.
