Five 4-layer rigid-flex PCBs were manufactured to the dimensions 320 × 14.5 mm and 0.8 mm finished thickness. The narrow aspect ratio and hybrid construction required exacting material preparation and flex-rigid lamination to align the polyimide flex layers with the FR-4 rigid sections while preserving mechanical integrity. 1 oz copper, 6/6 mil trace spacing, and 0.3 mm minimum holes were maintained throughout using standard geometry processes.
Green soldermask and white silkscreen were applied prior to electroless nickel and immersion gold deposition, yielding a uniform ENIG surface finish. Controlled depth routing isolated the rigid and flex zones without compromising the thin stack. Dynamic flex reliability testing was executed on the completed boards to confirm endurance under repeated bending cycles.
Full electrical testing verified net continuity and isolation. The 21-day production schedule accommodated the specialized lamination, routing, and validation steps, resulting in five consistent rigid-flex boards delivered for integration into compact electronic systems.
