This production record covers a batch of 250 rigid-flex panels, each a compact 4-layer construction measuring 38.95 × 40.24 mm with 1.0 mm finished thickness and 1OZ copper. The design used standard 6/6 mil track and spacing, 0.25 mm minimum holes, black soldermask, white silkscreen, and immersion gold ENIG surface finish. These parameters required exact control during material preparation and layer transitions to maintain alignment between rigid FR4 zones and flexible sections across the panelized format.
Inner layer imaging, circuit etching, and flex-rigid lamination were sequenced with high-pressure cycles to secure bond integrity at the junction lines. Controlled depth routing produced clean board outlines while protecting flex areas, followed by electroless nickel and immersion gold deposition for uniform pad coverage. Dynamic flex reliability testing, batch AOI inspection, and 100% electrical testing verified mechanical endurance and electrical continuity throughout the lot.
The 18.1-day schedule permitted full validation at each stage, resulting in consistent layer registration and surface quality suited to applications requiring both stability and repeated flexing. This execution reflects practical manufacturing considerations for small-form rigid-flex PCBs with ENIG finish from initial stack alignment to final delivery.
