These ten 4-layer rigid-flex panels, each measuring 85.65 × 305.4 mm at 1.6 mm thickness, required precise integration of rigid FR4 sections with flexible zones. Using 1 oz copper and 6/6 mil geometry, the boards featured 0.3 mm minimum holes, green soldermask, and white silkscreen. Production followed a dedicated flex-rigid lamination sequence after careful layer stack alignment and high-pressure pressing to maintain registration across the long, narrow panels.
Controlled depth routing accurately defined the flex-to-rigid transitions while avoiding damage to inner layers. The immersion gold ENIG finish was applied through electroless nickel deposition followed by immersion gold, providing uniform coverage and oxidation resistance. Dynamic flex reliability testing was performed to confirm the panels could endure repeated bending without trace fracture or delamination.
Electrical testing of all boards showed full continuity and isolation within specification. The 15.8-day schedule allowed thorough process control at each stage, delivering consistent rigid-flex PCBs suited for applications that combine mechanical flexibility with stable mounting areas.
