What is FPC and how is it produced?

Flexible Printed Circuit (FPC) is a highly reliable and excellent flexible printed circuit board made of polyimide or polyester film.

At present, the production process of flexible circuit boards mainly includes cutting, drilling, VCP, copper plating, dry film sticking, exposure.

Development, etching, dry film removal, decontamination cleaning, protective film application, lamination, pure tin, gold plating, silk screen printing, die cutting.

Electrical testing, reinforcement film bonding, functional testing and other processes.

FPC has the characteristics of high wiring density, light weight, thin thickness and good bendability.

FPC can be connected into a 3D circuit structure through three-dimensional assembly, so as to achieve the integration of component devices and wires, greatly reducing the volume of electronic products.

Widely used in consumer electronics, automotive electronics, industrial control medical and other fields.

The LCD FPC is a flexible circuit board that connects the panel and the external driver board, and is an important part of the display screen.
