This order consisted of 40 pieces of 4-layer rigid-flex PCBs measuring 105.4 × 268.5 mm with 1.6 mm thickness and 1 oz copper. The design integrated rigid FR-4 and flexible sections, necessitating exacting layer stack alignment and flex-rigid lamination to ensure reliable interlayer connections without delamination at the transition zones. Standard 6/6 mil geometry and 0.3 mm minimum hole size guided the imaging and drilling sequences.
Application of green solder mask and white silkscreen was followed by the ENIG surface finish. Electroless nickel deposition and immersion gold plating created a flat, reliable contact surface. Controlled depth routing accurately defined the board perimeters while protecting the flexible portions of the circuit.
Dynamic flex reliability testing validated the boards' ability to endure repeated bending, an essential step for this rigid-flex construction. Subsequent electrical testing confirmed that all 40 units met performance requirements. The production sequence, spanning 26 days, delivered consistent results aligned with the customer's specifications for dependable rigid-flex PCB functionality.
