This order involved the production of 110 units of 4-layer rigid-flex PCBs, each measuring 37.2 × 4 mm with an overall thickness of 0.4 mm. The combination of thin profile, 1 oz copper layers, and 4/4 mil minimum trace width and spacing required precise inner layer imaging, circuit etching, and layer stack alignment to maintain signal integrity across rigid-to-flex transitions while meeting the 0.2 mm minimum hole size.
High-pressure lamination and dedicated flex-rigid lamination steps ensured reliable material bonding for the single-board construction. Green soldermask with white silkscreen was applied, followed by immersion gold ENIG surface finish. Controlled depth routing created precise outlines that preserved the flexible zones required for the end application.
Dynamic flex reliability testing validated bending endurance, supported by full electrical testing that confirmed net continuity and isolation. The complete sequence, executed over 19.3 days, produced consistent boards with stable layer registration and dependable performance in a compact rigid-flex format.
