This production run delivered 30 panels of 4-layer rigid-flex PCB, each measuring 19 × 99 mm with 1.6 mm overall thickness and 1 oz copper weight. The stack used green soldermask, white silkscreen, immersion gold ENIG finish, 0.2 mm minimum holes, and conventional 6/6 mil track spacing. Because the design combined rigid sections with flexible circuits in panel format, particular care was given to material preparation, layer stack alignment, and the transition zones to prevent delamination or stress concentrations during bending.
High pressure lamination and flex-rigid lamination bonded the dissimilar materials reliably before controlled depth routing defined the flex areas. Dynamic flex reliability testing subjected sample circuits to repeated bend cycles, verifying mechanical endurance. Solder mask application, electroless nickel deposition, and immersion gold deposition were sequenced to maintain uniform coverage across both rigid and flex surfaces.
Electrical testing confirmed full continuity and isolation on every panel. The complete sequence from engineering review through final verification took 18 days and produced consistent results that met all specified requirements for these rigid-flex boards.
