Brief Introduction of FPC

Flexible Printed Circuit Board (FPC) is referred to as "soft board". In the industry, FPC is a printed circuit board made of flexible insulating substrate (mainly polyimide or polyester film), which has many advantages that rigid printed circuit boards do not have. For example, it can be freely bent, wound, folded. The volume of electronic products can be greatly reduced by using FPC, which is suitable for the development of electronic products in the direction of high density, miniaturization and high reliability. Therefore, FPC has been widely used in aerospace, military, mobile communication, laptop, computer peripherals, PDA, digital camera and other fields or products.

FPC also has the advantages of good heat dissipation, solderability, easy mounting and low cost.

Flexible printed circuit board has one layer, two layers and multilayer board. The base material is polyimide clad laminate. This kind of material has high heat resistance and good dimensional stability. It is the final product through pressing with the coating film which has both mechanical protection and good electrical insulation. The surface and inner conductors of double-sided and multi-layer printed circuit boards are metallized to realize the electrical connection of inner and outer layers.

The function of flexible circuit board can be divided into four kinds, namely, lead line, printed circuit, connector and multifunction integrated system, which cover computer, computer peripheral auxiliary system, consumer household electrical appliance and automobile, etc.
