2 Layer FR4 PCB Production Record #FR4-20260802-024

For this order of five single 2-layer FR4 PCBs measuring 87.5 by 40 mm, production followed the standard 1.6 mm thickness and 1 oz copper weight with 6/6 mil track spacing and 0.3 mm minimum hole size. Engineering review verified all parameters before material preparation, circuit imaging, etching, and green solder mask application with white silkscreen. The straightforward design without blind vias or impedance control allowed the sequence to progress smoothly from imaging through to final coating.

HASL Lead Free surface finish was applied via molten solder coating and hot air leveling, delivering a uniform protective layer suited to conventional 2-layer FR4 PCB assembly requirements. Electrical testing verified continuity and isolation on every board, confirming all five units met specification. The absence of advanced features kept process variables minimal while maintaining exact dimensional and electrical consistency across the small batch.

Completed in 1.7 days, the run produced reliable standard FR4 boards that align with expected performance for general electronics use. Each step was executed to support clean edges, accurate registration, and solderable surfaces ready for customer assembly.
