This production record covers five units of 4-layer rigid-flex PCB, sized at 119.87 × 109.66 mm with 1.0 mm finished thickness and 1 oz copper. The boards used 6/6 mil trace and spacing, 0.3 mm minimum holes, green soldermask, white silkscreen, and immersion gold ENIG finish. Material preparation and layer stack alignment received particular attention to ensure reliable bonding between rigid FR4 sections and flexible polyimide layers at the transition zones.
We performed flex-rigid lamination and high-pressure lamination under tightly controlled temperature profiles, followed by solder mask application, electroless nickel deposition, and immersion gold deposition. Controlled depth routing preserved the integrity of the flex areas while dynamic flex reliability testing verified bending endurance. Full electrical testing completed the sequence, confirming continuity and isolation across all five boards after the 26.4-day production cycle.
4 layer rigid-flex constructions deliver high density circuitry with mechanical flexibility for aerospace, medical, and industrial applications.
