For this rigid-flex PCB production run, we manufactured 50 boards in a 4-layer configuration measuring 32.1 x 101.8 mm with a finished thickness of 1.6 mm. The design utilized 1 oz copper layers and maintained standard 6/6 mil track and spacing along with 0.3 mm minimum hole sizes. Manufacturing began with thorough engineering review and material preparation, followed by precise circuit imaging, etching, and layer stack alignment to accommodate the hybrid rigid and flex requirements.
Flex-rigid lamination formed the core of the process, ensuring strong bonding between sections. After solder mask application in matte black and white silkscreen, the boards received an immersion gold ENIG surface finish through electroless nickel and immersion gold deposition. Controlled depth routing was applied to achieve accurate outlines while protecting flexible areas.
Dynamic flex reliability testing verified long-term performance under repeated bending cycles essential for this rigid-flex design. Final electrical testing demonstrated consistent results across the full batch, confirming that every board met the specified parameters for quality and durability in its intended application.
