This order consisted of 15 pieces of 2-layer FR4 PCBs, each measuring 230 x 130 mm with 1.6 mm thickness and 1 oz copper weight. The boards used standard 6/6 mil track and spacing, 0.3 mm minimum hole size, green solder mask, and HASL Lead Free surface finish. No silkscreen was applied and impedance control was not required. A custom stackup was followed throughout to match the specified layer configuration and overall dimensions.
We performed engineering review and material preparation before moving to circuit imaging and etching to define the conductors on the 230 x 130 mm panels. Solder mask application was completed next, followed by molten solder coating and hot air leveling to produce an even HASL Lead Free surface. These steps were sequenced to maintain flatness and coating quality across the relatively large board area.
Electrical testing was conducted on every board, verifying continuity and isolation. The full production run was completed in 4.2 days, yielding consistent thickness and finish across all 15 units. The executed process flow delivered boards that align with standard FR4 PCB expectations for this specification set.
