This order comprised 20 panels of 4-layer rigid-flex PCB, each measuring 106 × 295.5 mm with 1.6 mm thickness and 2 oz copper weight. The hybrid rigid-flex construction required precise layer stack alignment and flex-rigid lamination to integrate flexible zones without compromising structural stability or introducing stress concentrations. Standard 6/6 mil track spacing and 0.3 mm minimum hole size were maintained throughout, while the heavier copper demanded adjusted etching parameters to preserve trace integrity across both material types.
Inner layer imaging and circuit etching were followed by high-pressure lamination and thick copper electroplating to ensure uniform conductor thickness. Green solder mask was applied before electroless nickel deposition and immersion gold deposition to produce a reliable ENIG finish. Controlled depth routing defined the final panel outlines, respecting the transition areas between rigid and flex sections.
Dynamic flex reliability testing and full electrical testing verified bend endurance and net continuity across the entire batch. The 29.9-day production cycle allowed measured pacing through material preparation, multiple lamination cycles, and quality checkpoints, resulting in consistent boards delivered to specification for this rigid-flex application.
