What is a flexible circuit board | YMSPCB

Flexible Board , commonly known as FPC in the industry, is Printed Circuit Board made of Flexible insulating substrate (mainly polyimide or polyester film), which has many advantages that rigid Printed Circuit Board does not have. For example, it can be freely bent, wound and folded.

FPC can greatly reduce the volume of electronic products, suitable for electronic products to high density, small, high reliable direction of development. Therefore, FPC has been widely used in aerospace, military, mobile communications, portable computers, computer peripherals, PDA, digital cameras and other fields or products.

FPC also has the advantages of good heat dissipation and weldability, easy assembly and connection, low comprehensive cost.

FPC can be divided into single, double and multilayer boards.The substrate used is polyimide copper clad baord. This kind of material has high heat resistance, good dimensional stability, and the covering film with mechanical protection and good electrical insulation property is pressed into the final product. The surface and inner conductor of the double-layer and multi-layer printed circuit board are metallized to realize the electrical connection of the inner and outer circuits.

The functions of flexible Circuit board can be divided into four types, namely, Lead Line, Printed Circuit, Connector and Integration of Function. The uses of flexible Circuit board cover the range of computers, peripheral auxiliary systems of computers, consumer appliances and automobiles.

Flexible Board


At present, FPC has: single–layer, double–layer, multi–layer flexible board and Flex-Rigid board.


In the FPC flexible circuit board copying process, the customer asked the most question is time.


There are many reasons for the overflow of FPC flexible circuit board, and FPC manufacturers process parameters, preservation environment, staff operation, coverlay processing process and other related.


Flexible Printed Circuit (FPC) is a highly reliable and Flexible Printed Circuit board based on polyimide or polyester film.


FPC: isn't it common to say that Flexible Printed Circuit means Flexible and Printed Circuit board? It is a conductor circuit pattern made by light imaging pattern transfer and etching process method on a flexible substrate surface.


There are many reasons for the overflow of FPC flexible circuit board, and FPC manufacturers process parameters, preservation environment, staff operation, coverlay processing process and other related.


FPC(Flexible Printed Circuit) means Flexible Printed Circuit board.This kind of circuit board has the advantages of high wiring density, light weight and thin thickness and is widely used in mobile phones, laptops, PDA, digital camera, LCM and many other products.


In addition, FPC breaking is a problem in the early stage, which I personally think is not very difficult. The most fatal problem is FPC ringing, excluding the interference of FPC and over-hole. Do you have any good methods for FPC ringing?


FPC flexible circuit board in the process of processing if do not pay attention to touch the circuit board welding pad with your finger, especially do surface treatment of FPC, the flexible circuit board will cause oxidation.


FPC is the abbreviation of Flexible Printed Circuit, It has the characteristics of high density, light weight and thin thickness. So when designing FPC board, in order to be able to use them better, what are the requirements that we need to follow? The following is a understanding of PCB manufacturers.
