This production record covers 20 panels of 4-layer rigid-flex PCBs measuring 225 × 137 mm with 1.6 mm finished thickness and 2 oz copper on all layers. The design used standard 6/6 mil trace and spacing, 0.3 mm minimum holes, green soldermask, and no silkscreen. Immersion gold ENIG was selected for the surface finish to provide stable contact resistance and long-term protection on both rigid and flex transition zones.
We performed flex-rigid lamination after high-pressure rigid stack-up to ensure accurate alignment between flexible polyimide layers and FR4 sections. Controlled depth routing defined the exact bend areas while thick copper electroplating and subsequent etching maintained uniform 2 oz conductors. Dynamic flex reliability testing was conducted on sample panels to confirm the construction would withstand repeated bending without delamination or trace fracture.
Layer stack alignment, electroless nickel deposition, and final electrical testing were completed sequentially, resulting in consistent interlayer registration and impedance stability across the full quantity. The entire order from engineering review to shipment was executed in 18.7 days.
