Have you ever heard about Bay Area? Have you ever visited Bay Area? If any of these questions baffle you, and you love tech especially PCBs, then this article is meant for you. See, the San Francisco Bay Area is the area that is commonly known as the “Bay Area.” So what makes this place extra special, you might wonder? The Bay Area is famous for its:

• Picturesque beaches,
• Waterfront towns, and
• Tech-savvy found on its southern end, commonly known as the silicon valley.

The tech-savvy brings a lot of innovation to the world, which brings us to today’s question. Is PCB assembly Bay Area necessary, and is it beneficial?

However, before answering this question, let us have an overview of the Bay Area.

Bay Area

This region is densely populated, having a population estimate of around 7.753 million people. It surrounds the following bay estuaries found in northern California:

• The Suisun Bay
• Sean Pablo Bay
• San Pablo Bay
• San Francisco Bay

Even though the region’s boundaries are defined variously, the Bay Area is pretty much defined by the ABAG (Association of Bay Area Government). The association defines the area according to the nine different counties that border the estuaries we named above:

• Alameda
• Marin
• Contra costa
• San Francisco
• Sonoma
• Solano
• Santa Clara
• San Mateo
• Napa

According to the Association of Bay Area Government, the counties mentioned above make up the Bay Area.

So what makes the Bay Area great for PCB assembly? To answer this, we should look back a couple of years.

PCB Assembly Bay Area, Why is it necessary

Back in 1933, Naval Air Base found in Sunnyvale Was home to the USS Macon airship, now known as the Moffett Field. The Naval Air Base has grown over time to become one of the greatest research centers in the world, majoring in Aeronautic research. Other establishments have also grown alongside this Base. All trying to have a piece of this aeronautic technology development pie.

However, as these companies grew, so did the need for raw material they used to create prototypes and finished products. Remember we said that these companies were dealing with aeronautics mostly? So what do you think would be one of their most privileged raw material? Well, PCBs (Print circuit boards), of course. If you do not know what a PCB is, then here is a slight breakdown for you. A PCB is a sheet made of insulating materials with metallic circuits in printed form to conduct electricity in specific pathways.

The designing, developing, and manufacturing of PCBs is a never-ending cycle in the Bay Area due to their high demand. Almost every idea that comes out of Silicone valley found along the Bay Area comes the need to use a new PCB. With almost every research that companies around the Bay Area feature in, PCBs are needed. With this need for PCBs also came other requirements along with it, which include:

1. Changes in circuit board prototypes
2. Need for flexibility
3. Repeatable Quality which is pretty essential for the assembly of long term production

While many pcb manufacturers worldwide can satisfy some of these needs. Providing quality response services to electronic designers need locally operating manufacturers. So now you can see why PCB assembly Bay Area is pretty necessary.

Flexibility

Many print circuit board manufacturers found in the Bay area are well known for their great agility when it comes to servicing:

• Technologies
• Customers, and
• Orders.

These different shops specialize in medium volume, high-mix production. In doing so they get to regard and respond to their customer needs quickly and efficiently.

Customer needs might include:

• Design change – to fit their desired prototype
• Board enhancements – for new products

Flexibility is one major reason why PCB assembly Bay Area is pretty necessary as, without it, many companies would probably suffer.

Engineering Resources

One major reason for abrupt changes in print circuit board manufacturing is to accommodate changes in design due to:

•  Component or
• Performance issues.

Designers go through great stress thinking about the right:

1. Price
2. Product availability
3. Lead time

In some cases, PCB circuitry require a lot of modifications. Having onsite PCB engineers who are ready and willing to help out in:

• Providing pricing options
• Providing best quality options

While at the same time ensuring accuracy comes in handy. What’s more, if any designer decides that they need some circuitry changes, they can access engineering resources. All this saves the customer plenty of time and travel money, which boosts efficiency.

What’s more, PCB engineers have great experience in PCBs. As a result, they can offer design assistance to help minimize cost and time usage.

Local Services

Above all benefits of having PCB assembly in the bay area, designers have the privilege of working with local manufacturers. Here are some benefits of local services:

1. Designing teams in Bay Area have the advantage of working with PCB manufacturers. For optimal output, manufacturers allow onsite visits during the assembly process. The designers, onsite, help manufacturers complete their orders. They also help them make modifications, if necessary, to generate a perfect PCB for the designer projects.
2. Local services eliminate time differences and language barriers which in turn boost productivity.
3. PCB assembly in Bay Area leads to a great exchange of knowledge and information between manufacturers and design teams.
4.  And lastly, the delivery of complete products is faster, less expensive, and overall easier.

Trust

How much do you trust a person that you only meet online “exclusively”? And how much do you trust someone that you meet with face-to-face? You are most likely to trust a person you meet face to face more than you trust a person you only meet online. The same case applies to having PCB assembly in Bay Area.

Designers get to meet with manufacturers face to face, which boosts the trust between these two parties. A designer can hence trust that manufacturers will deliver on their said product. The manufacturers on the other hand can trust that they will get paid; this creates a great working environment.

Conclusion

PCB assembly Bay Area has proven to be one essential asset in the growth of tech and innovation in the Bay Area. Without PCB assembly in the Bay Area, profits would spiral downwards for many companies in the region. We hope that this article has enlightened you on the benefits of PCB assembly Bay Area and why it is necessary.

There are several materials for printed circuit boards. One of these materials or laminates are Isola laminates. These laminates are known for their high performance and usually feature in resin formulations. These laminates’ designs meet the needs of even very demanding requirements for complex printed circuit boards.

In this article, we will be answering whatever questions you have on your mind regarding the Isola FR402 PCB material. If you desire learning about the options necessary for treatment, the quality, features, benefits of this PCB material, we have everything covered in here.

Please join us as we explain further

What does the Isola FR402 PCB Material Mean?

The Isola FR402 PCB Material is a prepreg system and a laminate from Isola, which is made up of a well-developed epoxy-resin system with tetra functions.

This pcb material is best for any multi-layer PCB application, which require the performance properties that surpass those of epoxy-resin systems having di-functions.

Furthermore, the design of the Isola FR402 PCB Material construction helps in the enhancement of the precision and throughput of the AOI equipment.

However, the Isola FR402 PCB Material offers a great resistance to chemical and thermal degradation.

Main Features of the Isola FR402 PCB Material

The following are the main features of the Isola FR402 PCB Material

• It is available in some thicknesses, ranging from 0.05 mm to 3.2mm
• The prepreg of the Isola FR402 PCB Material is present as roll or panel
• Its flammability rating is UL94 V-0
• Furthermore, it makes use of glass styles, which includes 7629, 7628, 2313, 2116, 2113, 1652, 1080, 106.
• The Isola FR402 laminate is available in sheet or panel form
• The cladding of the copper foil includes double treat, reverse treat, and HTE

What Treatments are Available for the Isola FR402 PCB Material?

There are some treatments that are allowable for the effective bonding of the Isola FR402 epoxies. These include black oxide, brown oxide, red oxide, and double treat copper.

However, whenever you are making use of black oxide, make sure that the oxide is self-limiting. This prevents any excess oxide crystal.

However, it is possible to achieve efficient and enough bond strength making use of the different reduced and alternative oxides present.

Meet with the chemical supplier regarding the post baking aspects of the oxide whenever you are employing reduced or alternative oxides.

Why this is so is that extreme baking could cause reduced resistance of the pink ring. In addition, the inner layers have to pass through thorough drying. This is done in an oven even before lay-up.

In addition, the bake cycles usually range from 200 – 250 degrees Fahrenheit. Also, you can only use about 30 – 60 minutes.

Another important advice here is that the baking should be done in an upright rack that has panels held up vertically.

• TMA – Thermomechanical Analysis

Contamination Testing

Also, this test helps in sensing bulk Ionics. This is because these Ionics can contaminate the circuit boards, thereby causing abrasion, as well as other problems.

Test for Water Absorption

Moisture absorption can cause delamination, as well as other problems in the board of the Isola FR402, with exposure to any soldering heat. This test also helps in the examination of the rate of moisture absorption, as well as the bulk content of moisture of the FR402 printed circuit boards.

What Causes Outgassing in the Isola FR402 PCB Material?

The circumstances behind the occurrence of outgassing may be different. However, they have similar causes irrespective of the place it occurs.

Below are two major reasons why outgassing could happen in the Isola FR402 PCB Material.

Use of Incorrect Materials

When choosing an Isola PCB material, there’s a need for you to look into each stage of the life of the board. This includes the application and manufacturing.

Furthermore, plating that is formed from gold, silver, or tin can be made of salts or organics, which produces gas anytime heating during deposition.

Also, there is an increase in outgassing risk when a FR402 board is used in environments of high vacuum, which are made of material having higher outgassing chances.

Manufacturing Faults

The manufacturing process tells the quality of the Isola FR402 just like its materials. Any outgassing occurring during soldering occurs frequently when performing the process of pre-heating improperly or you apply an electroless copper plating that is very thin.

Furthermore, when you fail to get rid of the moisture when manufacturing of the Isola FR402 is on, it could cause the production of vapors, which are linked to off-gassing that usually occur in applications requiring high-vacuum.

Conclusion

We hope we have been able to properly explain what the Isola FR402 PCB Material offers to your understanding. From this article, this PCB material has excellent features and offers great benefits. This is why it is very suitable for different applications and will meet various pcb needs.

Most companies that manufacture electronic devices outsource PCB production to larger external companies. The companies that get these contracts have special tech and an adequate workforce to handle mass PCB production. However, not all companies offer full-on comprehensive PCB Assembly. Some just handle parts of the manufacturing process. If such a case occurs, the electronics manufacturing company must work with more than one Subcontractor to get the job done. But is working with a Subcontractor necessary? Is it beneficial to the electronics manufacturing company? And does it slow down or speed up the manufacturing process? To gain answers to this question, follow along as we immerse ourselves into the world of PCBs.

What does Subcontract PCB Assembly entail?

Before diving into what subcontract PCB assembly entails, let us first understand the term subcontracting to get us on track.

Subcontracting: It is the act of outsourcing or assigning a task and part of its obligations under a set contract to another firm/party.

Therefore, to subcontract PCB assembly involves the act of outsourcing PCB production to external firms.

What does the Subcontractor do?

The Subcontractor employs specialists who have great PCB manufacturing knowledge. They also have high-tech equipment they utilize to manufacture PCBs in bulk using little time.

Subcontractors offer their clients adequate support at:

1. The designing stage
2. Through-hole and surface assembly
3. Tests
4. Conformal coating
5.  Potting
6. Detailed quality control

What’s more, subcontractors might provide their clients with detailed documentation. The documentation is pretty useful as it provides details on the processes that occurred during production.

Once the manufacturing process is over, the Subcontractor moves on to the next stage, or shall we call it the inspection stage. In this stage, the Subcontractor utilizes a specialist to test and ensure that the PCBs are working properly before shipment. Reliable subcontractors carry out their testing based on international standards. They also check product quality, which is essential for companies looking to keep their clients. Remember, it only takes one bad shipment for things to go sideways, and manufacturers cannot take that chance. That is why this stage is pretty special.

Thanks to the inspection stage, clients can be sure that they will receive quality PCBs with little to no defects in their order. The result of this stage is durability and reliability, and an added bonus of limited complaints. In addition, subcontractors have reduced operating costs and gain maximum profits when this line holds.

When is it convenient to work with more than one contractor?

Working with multiple subcontractors affects the PCBs quality drastically. That is because, in this scenario, it becomes difficult for clients to verify every production stage. It especially gets harder when these subcontractors are working on one device. We hence recommend that you opt for multiple contractors only when the contract size gets too big for one contractor to handle.

Large subcontractors who can handle full-on PCB manufacturing always consider order profitability. Therefore smaller companies that order PCBs in lower quantities might sometimes face neglection. Hence even when working with one Subcontractor, always check on their reputation first. Fortunately, reputable subcontractors rarely look down on small or upcoming companies.

Another reason that would make a company deal with more than one Subcontractor is the need to generate a pretty specific product. For example, PCBs having THT assembly (through-hole) require special attention and manual intervention. Therefore, companies might opt to work with specialists who deal with manual assembly.

Why should you consider Subcontract PCB Assembly?

Are you looking to work with a subcontractor or subcontractors on your PCB project? Here are some reasons as to why this is a good idea:

Production speed and Accuracy

One great advantage of using Subcontractors instead of in-house manufacturing is that production speed goes up.

Subcontractors take months building and optimizing their machines to boost production speeds. On achieving this feat, their machines turn into PCB manufacturing beasts. They replicate PCBs in minutes, making mass production easy to achieve. High production rates also bring in high profits to the Subcontractor in terms of many units sold at once. Hence the price of one PCB becomes relatively less expensive.

Minimum time spent in the designing stage

The designing stage of a PCB is crucial as it dictates how the PCB will work. Messing up with the design renders the PCB useless.

The design procedure is labor-intensive for Subcontractors. You might be wondering how this even relates. They must ensure that the design is compatible with the components required. By letting the subcontractors work on the PCB design, you can save them a lot of production time.

Expansion

If you want to expand your company, subcontractors can help you out. If you are wondering how, then follow along to gain the answer.

Do you know how companies like to produce product lines consisting of different models? If you work with subcontractors, they can mass produce your PCBs in a custom manner. Once you get the PCBs, you can make slight modifications to create a custom product line.

In doing so, you can develop many products using less time, boosting your company’s expansion.

Access to the high-quality material

Most PCBs found in the market are built out of low-quality materials to reduce production costs. However, working with subcontractors can help you find the best material to produce your PCB. What’s more, they can attain this material at a really low price as they purchase the material in bulk.

Disadvantages of working with subcontractors

The initial investment is relatively higher

Outsourcing comes at a cost. Hence if you are looking to work with a subcontract PCB assembly company, you had better be ready to invest heavily in the project.

Lack of total control

When you are producing PCBs “in-house,” your company is fully controlling the manufacturing procedure. But once you outsource the production of PCBs to subcontractors, they take over control of this process. So you might be involved in the production process, but you will not have total control.

Conclusion

Subcontract PCB assembly is essential for companies looking to mass produce electronics at low costs. In doing so, these companies have a higher profit margin while at the same time producing quality products. Of course, it has its cons and pros, but overall the pros outweigh the cons. We hope that this article has provided you with all the answers you might have had regarding how to subcontract PCB assembly and why it is necessary. And as per the question, should you work with a subcontractor to develop your PCB? We recommend that you do, as far as the terms meet your requirements and needs.

Hence, this laminate can withstand the leakage of current flowing through its insulating laminate material. Therefore, for high volume resistance, one uses laminate that possesses little electric conductivity.

Glass Transition Temperature

In testing Shengyi SG7350D2, the glass transition temperature is important for testing. This implies, you begin to observe where its first state starts to modify based on heat application.

Also, at this point, you carefully look at the DMA which is a factor that influences the modification on heat application. The measurement of the tg is crucial when testing this laminate.

This glass transition temperature enables you to know where and when changes begin to occur in the first state of this laminate material. One tests the degrees of temperature that can modify this laminate from one state to another.

Surface Resistivity

This is also a property to test on the Shengyi SG7350D2 PCB. After you test the volume resistivity, the surface resistivity is not to be left out.

For the volume resistivity, it is the resistance to current leakage passing through the laminate. Then, the surface resistivity testing has to do with the minimal current this PCB laminate material can withstand without any leakage. Thus, if there’s a rise in surface resistivity, then there is leakage of increased current. At the end, it shows how bad a conductor the laminate is.

Dielectric Breakdown

You need to test the dielectric breakdown of the Shengyi SG7350D2. This implies, you study how this laminate may not be able to block passage of current. Hence, this results from indication that there is electric stress. When one applies too much of an electric stress, the laminate ceases to block current. Therefore, there is a specified voltage at which dielectric breakdown may occur.

Elasticity Modulus

In testing the Shengyi SG730D2, you need to check for any deformation that may possibly take place. This is due to heat application on the laminate. It should be able to withstand heat application without any deformity.
