For this rigid-flex PCB order, five 4-layer panels sized 152 x 170.7 mm were produced using 1 oz copper and a 1 mm board thickness. Specifications included a standard 6/6 mil minimum track and spacing, 0.3 mm holes, green solder mask with white silkscreen, and immersion gold ENIG finish. The hybrid construction called for precise flex-rigid lamination to ensure seamless integration between the flexible polyimide and rigid FR4 areas.
Manufacturing steps encompassed material preparation, inner layer imaging, high pressure lamination, solder mask application, electroless nickel and immersion gold deposition, and controlled depth routing. Dynamic flex reliability testing was executed to confirm the panels could endure repeated flexing, while electrical testing verified continuity and isolation across all layers.
Spanning 27.3 days, the production allowed for careful process monitoring on this small batch, resulting in consistent outcomes that satisfied the technical demands of the rigid-flex design. The boards were completed with reliable layer alignment and surface quality suitable for end-use applications.
