This 4-layer rigid-flex PCB order consisted of five panels measuring 214 × 191.5 mm with a finished board thickness of 1.0 mm. The stack used 1 oz copper throughout and required 5/5 mil trace width and spacing, paired with 0.25 mm minimum holes. Immersion gold ENIG surface finish was applied over green soldermask and white silkscreen, providing both corrosion resistance and reliable solderability for the mixed rigid and flexible zones.
Execution centered on precise layer stack alignment followed by high-pressure and flex-rigid lamination steps to maintain registration across material transitions. After solder mask application, electroless nickel and immersion gold deposition were tightly controlled. Controlled depth routing accurately defined the flexible areas, while dynamic flex reliability testing subjected the panels to repeated bend cycles before final electrical testing confirmed continuity and isolation on every board.
The complete process took 10.2 days and produced panels that met all mechanical and electrical criteria without deviation. The tighter geometry and specialized lamination approach ensured consistent performance suited to compact assemblies that demand both structural stability and flex capability.
