Manufacturing Process: How Flexible PCBs Are Made

Manufacturing Process: How Flexible PCBs Are Made is a blog article introducing you to the manufacturing process of Flexible PCB. The title tells us that this post will go in to detail on how flexible PCBs are made, so be prepared for some technical information if you decide to read this!

What is a Flexible Printed Circuit Board?

In the manufacturing process for Flexible PCB, a variety of materials and processes are used. Materials that are commonly used in flexible PCBs include polyimide, woven fabrics, and rubber. Polyimide is the most common material because it is strong yet flexible.

Woven fabrics are often used to create the substrate for flexible PCBs. The fabric is first laid down on a substrate such as acrylic or glass. Then, patterns are created using a computer-aided design (CAD) program. This allows for precise placement of the fabric around the circuit board.

Rubber is also often used in flexible PCBs. It is added as a layer between the fabric and the circuit board. This helps to create flexibility and durability in the finished product.

Where are Flexible PCBs Made?

A flexible PCB is a type of Printed Circuit Board (PCB) that has the ability to deform or stretch under normal use. This allows the PCB to more easily fit into tight spaces or to conform to irregular shapes.

Flexible PCBs are made using a variety of manufacturing processes, each with its own set of benefits and drawbacks. One of the most common methods is vacuum evaporation, which uses a heat source to evaporate a liquid plastic film onto a substrate. This method is generally used for small quantities of flexible PCBs since it is labor-intensive and can result in low yields.

Another popular method is inkjet printing, which uses an inkjet printer to deposit a plastic film onto a substrate. This method is often used for large quantities of Flexible PCB because it is fast and results in high yields. However, inkjet printing can also be prone to defects due to its high degree of accuracy.

Manufacturing Process of a Flexible PCB

A flexible printed circuit board (FPC) is a type of electronic board that can be bent and pulled in different directions. The manufacturing process for a flexible PCB starts with the creation of a substrate. This substrate can be made out of a variety of materials, including plastic, metal, or glass.

Once the substrate is created, the next step is to create the circuit boards. To do this, manufacturers use a variety of printing methods to create the circuitry on the boards. These methods include ink-jet printing, laser cutting, and electron beam lithography. Once the circuitry is printed onto the substrate, it’s then cut to size using various cutting tools.

After the circuits are cut, they’re then coated in a protective layer known as an adhesive coating. This adhesive coating helps protects the circuits from damage during the manufacturing process and during use by customers. Finally, the flexible PCBs are finished by heat-treating them to make them resistant to wear and tear.

Types of Materials Used in the Manufacturing Process

PCBs are made from a variety of materials. The most common PCB material is copper. Other common materials used in PCB manufacturing are plastics and composites. Flexible PCBs are made from a variety of flexible materials, such as silicone, rubber, and plastic.


PCBs are an important part of many technological devices. They can be found in everything from televisions to aircraft engines, and they play a vital role in connecting the various electronic components within these devices. PCBs are made using a flexible manufacturing process that allows for quick and easy changes to the designs of the boards. This flexibility is key to ensuring that PCBs meet the high standards demanded by today’s electronics industry.
