Understand the process flow of fpc flexible circuit board in a penny second

There are many processes involved in the production of fpc flexible circuit boards, from mechanical processing to ordinary chemical reactions to photochemistry, electrochemistry, thermochemistry and a series of computer-aided design CAM knowledge, etc., we can see that fpc flexible circuit boards The production process is complicated. Moreover, because the production of fpc flexible circuit boards is a non-continuous form, any mistakes in any of the links will have a great impact, and the suspension or the serious ones will lead to a large number of scraps. Let's take a look at the specific fpc flexible circuit board process flow?

The production process of fpc flexible circuit board""/Fpc flexible circuit board mainly includes:
Cutting - drilling - VCP - copper plating - dry film - exposure - development - etching - dry film removal - decontamination cleaning - protective film - lamination - pure tin - gold plating - silk screen - punching - electrical test - repair Strong film bonding-function test, etc.

Fpc flexible circuit board features:
1. It can reduce the volume of the product, greatly reduce the weight of the product, increase the effect, and reduce the cost;
2. It has a high degree of flexibility, can be wired three-dimensionally, and the shape can be changed according to the size of the space;
3. It can be folded without affecting the signal transmission, and can resist static electricity interference;
4. High and low temperature resistance, flame resistance.
5. Stable chemical changes, high stability and reliability.
6. To increase the service life of related products.
Fpc flexible circuit board process flow Fpc flexible circuit board function:
1. The flexible board has the functions of lead wire, printed circuit, connector, and lead wire of multi-function integrated system;
2. Connections between rigid circuit boards, three-dimensional circuits, movable circuits, and high-density circuits;
3. Printed circuit: high-density thin three-dimensional circuit connector
4. Low-cost hard board connection multi-action integration system
5. Integration of hard board lead wires and connectors
The above is the introduction of some related knowledge of fpc flexible circuit board, I hope it will be helpful to you!
