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 production: cover film cutting → drill positioning holes → cover pre-processing → apply cover film
Combined production: Pressing → Copper reduction → One-time drilling → Copper sinking → Board electricity → Outer layer circuit → Outer layer pattern plating → outer layer etching → Outer layer QC inspection board → Outer layer AOI test → Mid-level test → Solder mask pretreatment → Solder mask → Pressing accessories → FPC fast pressing → Immersion gold → Gong board → Deep control gong → Gong board → Laser lid opening → Electrical measurement →FQC/FQA→ Finished board washing→ Packing
3. Application areas
This is a black double-sided flexible and rigid board, it is a battery protection board. The rigid board area is used for welding components, and the flexible board plays the role of connection and bending. Because the flexible board is pasted with a black covering film, the flexible board part is black.
