This production record covers 50 pieces of 4-layer rigid-flex PCB, each measuring 114 x 24 mm with a board thickness of 1.6 mm and 2 oz copper on all layers. Manufacturing involved standard 6/6 mil trace and spacing together with 0.3 mm minimum holes. The surface was finished with immersion gold ENIG over green soldermask and white silkscreen, requiring exact registration between rigid FR4 sections and flexible zones to maintain mechanical integrity without blind vias.
The sequence began with engineering review and material preparation, followed by inner layer imaging, circuit etching, high-pressure lamination, and flex-rigid lamination. We applied thick copper electroplating and controlled etching to accommodate the heavier copper weight, then performed solder mask application, electroless nickel deposition, and immersion gold deposition. Dynamic flex reliability testing verified the transition areas could endure repeated bending.
Controlled depth routing prepared the final outlines before 100% electrical testing confirmed continuity and isolation across the full batch. The 17.1-day schedule delivered consistent plating thickness and layer alignment, meeting all specified requirements for this rigid-flex order.
