These five panelized 4-layer rigid-flex PCBs measured 180 by 120 mm with 1.6 mm finished thickness and 1 oz copper throughout. The build followed a standard 6/6 mil track and spacing geometry together with 0.3 mm minimum holes, black soldermask, white silkscreen, and immersion gold ENIG surface finish. No blind vias were required, allowing focus on the hybrid stackup where rigid FR4 sections transition into flexible layers.
Production began with detailed engineering review and material preparation matched to the rigid-flex construction. We performed precise layer stack alignment, high pressure lamination, and flex-rigid lamination to ensure stable bonding at the interfaces. Solder mask application preceded electroless nickel and immersion gold deposition, after which controlled depth routing accurately defined the flex regions without damaging adjacent circuitry.
Dynamic flex reliability testing confirmed the panels could endure repeated bending cycles, followed by full electrical testing that showed all boards within specification. The 28-day schedule permitted careful process monitoring for this low-volume order, yielding consistent mechanical and electrical performance suited for end-product integration.
