1. Laminated structure
2. Production process
Soft board cutting → drilling → circuit etching → AOI scanning → pressing and covering film → pressing → drilling → sinking copper plate electricity → outer circuit etching (alkaline etching) → AOI scanning → solder mask characters → opening and forming → Mechanical depth control → immersion gold → pressure PI reinforcement → electrical measurement → rigid board forming → soft board forming → FQC → packaging
3. Application areas
This rigid-flex board is a consumer electronics product, and it is used in remote control aircraft. Because the remote control drone needs high-definition shooting, it has better signal consistency and also can effectively save the internal space of the rigid-flex board, which is a better choice than the cable.
