This 4-layer rigid-flex PCB order comprised 20 panels sized 186 × 111.6 mm at 1.6 mm thickness with 2 oz copper throughout. The design used standard 6/6 mil trace and spacing, 0.3 mm minimum holes, green solder mask, and immersion gold ENIG finish without silkscreen. Material preparation and inner layer imaging established accurate flex and rigid zones, after which we performed flex-rigid lamination and high pressure lamination to integrate the dissimilar sections reliably.
Thick copper electroplating and controlled copper etching maintained uniform 2 oz weight while preserving trace profiles. Layer stack alignment was verified at each stage to avoid registration errors typical of rigid-flex constructions. Solder mask application, electroless nickel deposition, and immersion gold deposition followed, delivering a clean, oxidation-resistant surface suited to the board's mixed mechanical demands.
Controlled depth routing prepared precise outlines, and dynamic flex reliability testing confirmed the panels endured repeated bending cycles without delamination or conductor fracture. Full electrical testing completed the 18.7-day schedule, yielding consistent performance across the full lot and meeting all dimensional and functional requirements for this rigid-flex PCB.
