This production record covers 100 pieces of 2-layer FR4 PCBs, each measuring 240 x 135 mm with 1.6 mm thickness. The design used 1 oz copper weight and maintained a standard 10 mil track and spacing, along with 0.4 mm minimum hole size. Without impedance control or blind vias, the manufacturing followed established procedures for conventional double-sided boards.
Black soldermask and white silkscreen were applied after the etching stage. The HASL Lead Free surface finish was achieved through controlled molten solder coating and hot air leveling, delivering a flat, uniform surface across all boards. Subsequent electrical testing verified full functionality and compliance for the complete batch.
Production wrapped up in 2.3 days, with steady process parameters maintained throughout to ensure consistent results.
2 layer FR4 PCBs deliver cost-effective solutions for most electronic designs. Their simple structure enables consistent quality and efficient production cycles.
