This order comprised five 6-layer flexible PCBs produced in panel format, each measuring 500 × 50 mm with a finished thickness of 0.23 mm. Manufactured on polyimide with rolled copper foil, the design specified 3/3 mil trace and spacing together with 0.1 mm minimum holes. These tighter geometry requirements drove detailed inner layer imaging, circuit etching, and precise layer stack alignment to maintain registration across all layers while preserving the panel's inherent flexibility.
Polyimide material handling received close attention during preparation to avoid distortion in the thin construction. High-pressure lamination bonded the stack, followed by coverlay lamination in place of soldermask. Electroless nickel and immersion gold deposition formed a uniform ENIG finish on exposed copper. Subsequent dynamic flex testing and full electrical testing confirmed mechanical endurance and interlayer continuity for every panel.
The 25-day production window permitted methodical process controls at each stage, delivering panels with repeatable electrical and bend characteristics suited to compact multilayer flex applications.
