This production record covers 20 panels of 4-layer rigid-flex PCBs built to 171 × 106 mm dimensions and 1.6 mm finished thickness, using 2 oz copper on all layers. The design followed a conventional 6/6 mil trace and spacing requirement with 0.3 mm minimum holes, green soldermask on rigid zones, and no silkscreen. Immersion gold ENIG was selected as the surface finish to support reliable contact points in both rigid and flex areas.
Execution centered on accurate flex-rigid lamination after high-pressure bonding of the flexible polyimide layers to FR4 sections. Thick copper electroplating established the 2 oz weight, followed by controlled etching, solder mask application, electroless nickel deposition, and immersion gold plating. Controlled depth routing produced clean panel outlines while preserving flex transition zones.
Dynamic flex reliability testing and 100 % electrical testing confirmed mechanical endurance and circuit continuity across all panels. The 18.7-day schedule delivered consistent registration and quality that matched the rigid-flex requirements without deviation.
