This order comprised 250 units of 4-layer rigid-flex PCBs measuring 8 × 31.7 mm and only 0.4 mm thick. With 4/4 mil trace width and spacing, 0.2 mm minimum holes, green soldermask, white silkscreen, and immersion gold ENIG finish on 1 oz copper, the tighter geometries on a thin rigid-flex construction required precise process controls during imaging, etching, and layer stack alignment to preserve registration across material transitions.
Manufacturing followed a disciplined sequence of flex-rigid lamination, solder mask application, electroless nickel and immersion gold deposition, controlled depth routing, and dynamic flex reliability testing. These steps ensured the boards could endure repeated bending without compromising circuit integrity. Batch AOI inspection and full electrical testing confirmed consistent results across the entire run.
The complete cycle from engineering review through final verification took 18.3 days, yielding reliable rigid-flex boards that fully satisfied the dimensional, electrical, and mechanical requirements of the design.
