This order comprised five 4-layer rigid-flex PCBs, each 102 × 193 mm and 1.6 mm thick, built on 1 oz copper with 5/5 mil minimum trace and spacing. The tighter geometry required exact inner layer imaging and etching to maintain trace integrity across both rigid and flexible zones. Black soldermask, white silkscreen, and immersion gold ENIG surface finish were applied, providing good contrast and reliable contact surfaces without nickel over-etching.
Manufacturing followed a disciplined sequence of flex-rigid lamination, high-pressure bonding, and controlled depth routing to protect the polyimide flex areas. Dynamic flex reliability testing was performed on each board to confirm bend endurance at the transition zones, followed by 100 % electrical testing. The 8.8-day schedule accommodated the multiple lamination cycles and iterative verification required for this hybrid construction.
All five boards were delivered within specification, demonstrating consistent layer registration and solderability. The combination of rigid-flex technology, ENIG plating, and verified flex endurance produced parts ready for direct integration into the end application.
