Manufacturing Summary
This rigid-flex PCB order comprised 120 four-layer boards measuring 53 × 163 mm with 1.0 mm thickness and 1 oz copper. The 5/5 mil minimum track and spacing required precise inner layer imaging, etching, and stack alignment to maintain feature integrity across rigid-to-flex transitions. Yellow soldermask, white silkscreen, and immersion gold ENIG surface finish were applied, with plating parameters adjusted to achieve uniform nickel and gold deposition on both material types.
Flex-rigid lamination and high-pressure bonding were sequenced to prevent stress concentrations at the junction zones, followed by controlled depth routing for clean outlines. Dynamic flex reliability testing subjected the boards to repeated bend cycles while electrical testing verified net continuity and isolation on every unit, confirming zero defects across the full lot.
Completed in 19.3 days, the run delivered consistent rigid-flex PCBs that satisfied all dimensional, mechanical, and electrical requirements for applications combining stable circuitry with dynamic flexing sections.
