1. Laminated structure
2. Production process
Rigid board production: rigid board cutting → drilling positioning holes → rigid board inner layer etching → AOI scanning
FPC production: FPC cutting → drilling positioning holes → FPC circuit etching → AOI scanning
Cover film: cover film cutting → drill positioning holes → cover pre-processing → apply cover film
Flexible board cutting → auxiliary material cutting → rigid board cutting → laser cutting → one-time drilling → black hole → flexible board circuit → flexible board etching → flexible board electroplating → flexible board AOI test → laser cutting → rigid board inner layer etching → rigid board AOI test → total
3. Manufacturing difficulties
The inner flexible board is electroplated copper, thick copper NF PP is pressed and filled with glue. The front and back laser-controlled deep opening process. The flexible board and the rigid board sub-area impedance process.
4. Application areas:
This rigid-flex board is used in industrial connectors. Advantages of the application of rigid-flex board in the field of industrial equipment:
Compared with the traditional cable, it can effectively reduce the volume. At the same time, since the flexible board and the rigid board is combined by lamination, the stability is better when transmitting signals.
