Top Factors to Consider When Selecting a Flex PCB Manufacturer

Factors to select a flex PCB Manufacturer

Electronic manufacturers often face the challenge of integrating conflicting requirements into a finished circuit board. Consumer products today are becoming more compact and complex than ever before. They need to withstand varied environmental conditions without compromising their functionalities.

You are more likely to use electronic devices such as smartphones and laptops daily at work, school, or home. Over the years, smartphones and laptops have undergone significant changes since these devices were first introduced to consumers. For example, mobile phones have dramatically changed in the last 20 years. When it was invented in 1973 by Motorola, it weighed nearly 2 kilograms, but now, mobile phones are far more lightweight. Samsung smartphones today have an average weight of a little over 164 grams. Despite being lighter, smartphones nowadays are far more powerful and have more functions than the first mobile phones.

These innovations are all made possible with the development of modern circuit boards, such as introducing flexible PCBs, better known as flex PCBs. Its name already implies its capability. A flex PCB manufacturer loves to utilize flexible PCBs because of their bendability, and yet they can withstand heavy loads without breaking. Flex PCBs are also very thin, making them very lightweight and ideal for modern-day electronic devices.

Many flex PCB manufacturers find it advantageous to use flex PCBs in electronic devices. Compared to other PCBs, flex PCBs have better heat dissipation and allow better airflow. They are also less expensive since they contain a moderate number of interconnections and components. Flex PCBs have become the preferred choice for binding compound electronics internal systems.

Usage of Flex PCB Manufacturer

Since the flex PCB invention in the 1960s, manufacturers have preferred them because they are circuit boards ideal for today’s electronic devices. Flex PCBs were initially developed for high-precision devices in the military and aerospace industries.

Usage of flex PCB manufacturers

1. Flex PCB usage in the automotive industry

Flex PCBs are being used in electronic devices in the automotive industry. Wiring harnesses in the automotive sector are simply considering a vehicle’s weight. Flex PCBs are a perfect match for automobile production: they can withstand car bending without damaging the wires. It also allows flex PCB manufacturers to design the circuit boards based on their requirements without compromising their capabilities. Moreover, it is heating resistant and durable, which makes it suitable for various electronic components for automobiles, such as gearboxes, LED car lights, navigation systems, car displays, sensors, and entertainment systems.

2. Flex PCB usage in the smartphone industry

Another significant application of flex PCBs is they made the multi-functionality of smartphones possible. Smartphone makers always find ways to innovate their products and enhance their functions to meet consumers’ demands. As a result, there is an increasing demand for flex PCBs to make smartphone components. Initially, manufacturers utilized it for LCD panels, batteries, buttons, and camera modules. However, with the advent of biometrics technology, demand for flex PCBs further increased as they became vital in making components for fingerprint applications, multiple cameras, and face recognition functions.

3. Flex PCB usage in the medical industry

Flex PCBs are also used in wearable medical devices that gather physiological data. Since these devices are wearable, they should not make people uncomfortable when they wear them. Hence, the product needs to be compact and lighter. Flex PCBs play a vital role in making this happen.

Factors to consider in the selection process

Finding the proper flex PCB manufacturer may become tricky and challenging. Here are six factors you can use to select one:

1. Final product’s quality

It is crucial to factor in the product quality of a flex PCB manufacturer. Even if the supplier can deliver in vast quantities quickly, the quality should be better; you might end up with many PCBs you cannot use. Quality should always be the top consideration when selecting a flex PCB manufacturer to ensure you get the best out of your money.

You can do a little research by checking on the quality of the final product they have supplied to previous clients. You can ask the potential flex PCB manufacturer about the specifications and features of its PCBs to determine if it meets your requirements.

2. Customization

Another essential factor to consider is the capability of the potential flex PCB manufacturer to customize. It should be able to tailor the circuit boards based on your needs and not make one-size-fits-all PCBs. Every project has a unique set of requirements, and so does yours. Do they have the capability to create PCBs based on your design? You can see their previous works to see the level of customization that they can do. The PCBs that they will produce should be tailored to fit your needs.

3. Qualified technicians

It is also essential to check if the flex PCB manufacturer bidding for your project has qualified technicians to do the job. Flex PCBs have only recently become part of the manufacturing industry. Only some PCB producers today are highly skilled in making flex PCBs. Hence, it is vital to check if the supplier has qualified and skilled professionals to create PCBs. Becoming an expert in making flex PCBs takes a great deal of understanding.

4. Storage and shipping

You should also check that the flex PCB manufacturer has a good storage facility once the production is done. If PCBs are not well kept, they might get damaged, which could affect the deadline for product delivery.

The potential supplier should also have systematic logistics to deliver the circuit boards undamaged. Poor shipping practices could damage the PCBs while transporting them. Better packaging of the finished PCBs can help secure them while being delivered to you.

5. Pricing

Cost is always a key consideration in any project since you are working within a specific budget. Thus, you need to ask potential suppliers for a cost quotation for making flex PCBs. You can shortlist suppliers whose pricing is within your budget. It is an exercise in futility to continue discussing with flex PCB manufacturers whose costs are much higher than your budget because, in the end, you might not be able to afford them.

6. Customer support

It would also be good to check if a potential flex PCB manufacturer has excellent customer support. Remember that during the project, you will constantly discuss the circuit board details that you want with them. The supplier must be responsive to your inquiries. Along the way, as the project progresses, there might be some changes in the specifications of the final product. Hence, it is crucial that they can get to you quickly to address such issues.


Selecting a suitable flex PCB manufacturer for your business is essential for success. PCBs have become vital in making components for various electronic products, like those used in the telecommunication and automotive industries. Flex PCBs allow the creation of components that are both durable and lightweight. Further, flex PCBs are best used for complex internal systems of electronic components. When selecting a flex PCB manufacturer, this checklist could serve as a guide to looking for a potential supplier.
