This order involved manufacturing 20 panels of 4-layer rigid-flex PCBs, each measuring 199 × 411 mm with 1.6 mm thickness and 2 oz copper weight. The design followed standard 6/6 mil trace and spacing rules, with green solder mask and ENIG immersion gold finish but no silkscreen. The rigid-flex construction required exact material selection for both FR4 and polyimide sections, along with precise layer stack alignment to maintain reliable transitions between rigid and flex zones during flex-rigid lamination.
High-pressure lamination secured the stack, after which thick copper electroplating and controlled etching produced uniform 2 oz conductors. Solder mask application preceded electroless nickel and immersion gold deposition. Controlled depth routing created clean panel outlines while preserving flexible areas. Dynamic flex reliability testing was performed to confirm the panels could endure repeated bending without delamination or trace damage.
Electrical testing verified continuity and isolation across all 20 panels. The 26.9-day production schedule accommodated the additional steps inherent to rigid-flex fabrication, ensuring every board met dimensional and performance requirements with consistent quality.
