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.
