This 4-layer rigid-flex PCB production consisted of 20 panels, each 24.6 x 105 mm in dimension and 1 mm in thickness. Built with 1 oz copper layers and adhering to 6/6 mil minimum track and spacing rules, the boards featured 0.25 mm holes, black soldermask, white silkscreen printing, and an immersion gold ENIG finish. The rigid-flex configuration necessitated specialized flex-rigid lamination and controlled depth routing to properly define the flexible areas.
Following detailed engineering review and material preparation, the inner layers underwent imaging and etching prior to stack alignment and high-pressure lamination. Solder mask was applied after the lamination steps, succeeded by electroless nickel deposition and immersion gold plating. Dynamic flex reliability testing played a critical role in confirming the mechanical endurance of the flex sections.
Electrical testing at the end of the 15-day manufacturing cycle ensured full functionality. The executed processes resulted in panels that meet the required consistency for applications involving both rigid stability and dynamic flexing.
