This production record covers ten long-format panel PCBs built as 2-layer FR4 with 6oz copper on both sides. The boards measure 76 × 524 mm and 1.6 mm thick, using a 20/20 mil trace and spacing paired with 0.3 mm minimum holes. Green soldermask, white silkscreen, and lead-free HASL were applied over the custom stackup, delivering the heavy copper PCB required for high-current applications.
Manufacturing followed a sequence of engineering review, material preparation, circuit imaging, thick copper electroplating, and controlled copper etching to maintain trace geometry across the extended panel length. Solder mask application, molten solder coating, and hot air leveling were calibrated for uniform coverage on the large panels, after which every board completed full electrical testing.
The 16.9-day build cycle accommodated the additional plating and etching time inherent to 6oz copper while ensuring dimensional stability and consistent surface finish across the full set.
