This 4-layer rigid-flex PCB order consisted of 10 boards with dimensions of 500 × 128 mm and a finished thickness of just 0.6 mm. The stack used 1 oz copper throughout, 4/4 mil trace width and spacing, 0.2 mm minimum holes, green soldermask, and immersion gold ENIG finish. These parameters required precise material selection and registration control during flex-rigid lamination to prevent stress concentrations at the transition zones while preserving the thin cross-section.
Production followed a sequence of inner layer imaging, circuit etching, high-pressure lamination, and controlled-depth routing to create clean flex contours without compromising the rigid sections. Dynamic flex reliability testing was performed after electroless nickel and immersion gold deposition to validate bend endurance specific to this elongated form factor. The absence of silkscreen simplified the solder mask process yet still demanded uniform coverage across both material types.
All boards passed electrical testing after 26.1 days of fabrication, confirming consistent interconnect integrity and plating quality. The executed process steps delivered reliable rigid-flex performance tailored to the tight geometries and thin profile of this build.
