This production record covers 15 four-layer rigid-flex PCBs built to 47.45 × 69.86 mm dimensions and 1.2 mm finished thickness. With 4/4 mil minimum trace and spacing on 1 oz copper, the circuit geometry demanded exact inner-layer imaging and etching to preserve signal integrity across both rigid and polyimide flex zones. Material preparation, layer-stack alignment, and flex-rigid lamination were sequenced to prevent delamination while maintaining the required bend radius.
Matte black solder mask was applied uniformly before electroless nickel and immersion gold ENIG deposition, delivering a flat, solderable surface without nickel over-etch. Controlled-depth routing accurately defined the rigid-flex transition areas. Dynamic flex reliability testing and full electrical testing confirmed continuity and isolation after 28 days of controlled processing, ensuring every board met the mechanical and electrical criteria before shipment.
