This production run delivered 20 panels of 4-layer rigid-flex PCB, sized at 87.7 × 47 mm with 1 mm thickness and 1 oz copper throughout. Standard 6/6 mil track and spacing were paired with 0.25 mm minimum holes, green soldermask, white silkscreen, and immersion gold ENIG surface finish. These choices supported reliable component attachment while accommodating the mixed rigid and flexible material stack required for the design.
Manufacturing followed a disciplined sequence of inner layer imaging, circuit etching, and high-pressure lamination before the critical flex-rigid lamination step. Precise layer stack alignment prevented misalignment at the transition zones. Controlled depth routing accurately defined the flexible areas, after which dynamic flex reliability testing confirmed the panels could endure repeated bending cycles without trace fracture or delamination.
Electroless nickel and immersion gold deposition produced a uniform, oxidation-resistant finish across all panels. Final electrical testing verified continuity and isolation on every board. The complete order was executed in 20.8 days, resulting in consistent rigid-flex circuits that matched the customer's mechanical and electrical requirements.
