We produced five single 2-layer FR4 PCBs measuring 113.05 x 74.58 mm with 1.6 mm thickness and 1 oz copper layers. The design followed conventional 6/6 mil track and spacing rules together with 0.3 mm minimum hole sizes. Using a default stackup and omitting impedance control allowed standard processing flows, completed with green soldermask, white silkscreen, and HASL Lead Free surface finish.
The sequence began with engineering review and material preparation, then moved to circuit imaging and etching for accurate pattern transfer. Solder mask application preceded the molten solder coating and hot air leveling steps that establish the lead-free HASL finish. This approach ensures good flatness and reliable soldering performance for the boards.
Final electrical testing confirmed that all units met quality standards, with the full production completed in 3.4 days. The outcome reflects steady execution for this small batch of standard FR4 PCBs, delivering consistent results aligned with the provided specifications.
