This order consisted of five single 2-layer FR4 PCBs measuring 73.15 × 182.07 mm, built to 1.6 mm thickness with 1.5 oz copper weight on both layers. The design called for 6/6 mil minimum trace and spacing together with 0.3 mm minimum hole size, placing the board comfortably within conventional fabrication tolerances. We performed an engineering review of the default stackup and then moved through material preparation and circuit imaging with particular attention to the heavier copper foil to maintain uniform etch depth and line consistency.
Green solder mask and white silkscreen were applied prior to molten solder coating and hot air leveling, producing a reliable HASL Lead Free finish across all boards. The process sequence ensured even solder distribution without bridging on the standard geometry. Electrical testing verified netlist integrity on every board, confirming that the finished 2-layer FR4 PCBs met all continuity and isolation requirements.
Completed in 1.5 days, the run delivered five consistent boards that reflect routine production execution rather than specialized controls. The combination of 1.5 oz copper and HASL Lead Free surface finish provides solid mechanical strength and assembly compatibility for this compact rectangular design.
