This production run delivered 30 panels of 4-layer rigid-flex PCBs, each measuring 161 × 155 mm with a finished thickness of 1.6 mm and 2 oz copper throughout. The design followed standard 6/6 mil trace and spacing with 0.3 mm minimum holes, green soldermask, and immersion gold ENIG finish while omitting silkscreen. Material preparation and layer stack alignment received close attention to accommodate the differing thermal expansion rates between rigid FR-4 and flexible polyimide sections.
Flex-rigid lamination and high-pressure lamination steps were sequenced to maintain precise registration across the transition zones. Thick copper electroplating, followed by controlled copper etching, preserved trace profiles on the heavier copper weight. Dynamic flex reliability testing validated bend endurance, and 100 % electrical testing confirmed net integrity on every panel before controlled depth routing defined final outlines.
The order was completed in 15.9 days with stable dimensional and electrical results across the batch. The combination of ENIG plating and verified flex reliability supports consistent performance in applications requiring both mechanical flexibility and robust soldering interfaces.
