Brief Introduction of Flexible Printed Circuit (FPC)

As we all know that FPC is widely used in the mobile phones. It can connect the LCD and Mainboard, Side Key with Mainboard, which a normal rigid PCB can not achieve.
FPC, full name is Flexible Printed Circuit), is made of polyimide or mylar, an insulation material.
Flexible Printed Circuit (FPC) can be folded, bended freely. Besides, FPC is with very light weight, small volume, well heat dispersion, easy installation.
Flexible Printed Circuit (FPC), with it’s advantage of helping to make the electronic products with high density, now it’s widlely used in the area of aerospace, military, mobile communication, laptop, PDA, computer, camera, etc. Meanwhile Flexible Printed Circuit (FPC) also has some disadvantages, like not that durable, harder design and engineering, low possiblity of fix up, harder inpection, higher cost, etc. But these are not big problems compared with the advantages of Flexible Printed Circuit (FPC) can bring to us. That’s why it becomes more and more important and more often used in the electrics and telecommunication industries.

Structure of Flexible Printed Circuit (FPC)

Flexible Printed Circuit (FPC) can be single layer and multilayer.
Usually when we refer to the single layer FPC, it has only 1 layer of copper. But actually it has 5 layers (including adhesive, while the stiffiner not include), and normal double sided FPC has 1 inner layer (base film) with 1 layer of copper opn each side. But actually it has 9 layers (including adhesive, while the stiffiner not include).
