Flexible Printed Circuit (FPC)
Flexible Printed Circuit (FPC), also known as flex PCB, are electronic circuit boards made of flexible substrates (such as polyester film). Compared to traditional rigid printed circuit boards (PCBs), FPCs are characterized by their flexibility, light weight, and ability to bend, allowing for flexible arrangement of electronic components in limited spaces.
Why Choose Flexible Printed Circuit
- When the product is very compact and space-constrained.
- When PCBs cannot achieve the necessary connections.
- When the product requires a lightweight design.
- When the product has bending design requirements.
Flexible Printed Circuits are widely used in electronic applications and can be found in many of the products we use in our daily lives.

Applications for flexible printed circuit
Key issues need to be carefully considered in the design and production of flexible printed circuits to ensure that the final product exhibits good performance and reliability.
Material selection—-Choosing the correct flexible substrates and conductive materials is essential, impacting the flexibility, durability, and performance of the circuit board.
Circuit layout–— When designing the circuit layout, consider the flexibility and space usage of the flexible board. A thoughtful layout prevents circuit damage when bent and optimizes board surface area.
Manufacturing processes—-Manufacturing flexible circuit boards involves special techniques different from rigid ones. It includes substrate lamination, conductive material etching or printing, and testing bending performance.
Flexibility—-Bending performance is crucial in flexible circuit board design and production. Factors like bending radius, number of bends, and circuit functionality stability after bending should be considered. Ensuring continuous functionality despite bending is vital.
Reliability—-Since flexible circuit boards are often used in special environments and applications, reliability is crucial. Strict quality control and testing during the production process are necessary to ensure that the flexible circuit board exhibits good stability and durability during use.

Materials for Flexible Printed Circuit
Copper foil ——refers to the conductive material used in flexible printed circuit boards (FPC), which is usually copper foil. The main function of FPC copper foil is to form the circuit pattern on the substrate of FPC and provide conductive function. Specifically, FPC copper foil is pressed onto the substrate of FPC in the manufacturing process, and then the circuit pattern is formed by chemical etching or laser ablation. After the circuit pattern is formed, FPC copper foil becomes the conductive path in the FPC circuit, allowing the circuit to transmit signals and power.
