This 4-layer rigid-flex PCB was built as a set of 10 single boards measuring 129 × 56 mm with 1.0 mm finished thickness and 1 oz copper. The design used standard 6/6 mil trace and spacing, 0.3 mm minimum holes, green soldermask, white silkscreen, and immersion gold ENIG finish. These parameters required careful material selection and process sequencing to integrate the rigid FR4 sections with the flexible areas while preserving dimensional stability.
Engineering review and stackup impedance engineering were completed first, followed by trace width compensation, inner layer imaging, and precise circuit etching. Flex-rigid lamination and high-pressure bonding steps received particular attention to ensure clean transitions without delamination risk. After solder mask application, electroless nickel and immersion gold deposition were performed, then controlled depth routing defined the final outline.
Each board underwent TDR impedance testing, dynamic flex reliability testing, and 100 % electrical testing to confirm both electrical performance of the impedance controlled PCB and mechanical endurance of the flex zones. The complete order moved through all process stages in 22.1 days and was delivered with consistent quality matching the specified requirements.
