This production record covered five single 2-layer FR4 PCBs sized 76.68 × 86.11 mm with standard 1.6 mm thickness and 1 oz copper weight. The 10/10 mil track and spacing combined with 0.3 mm minimum holes aligned directly with our conventional process capabilities, allowing straightforward circuit imaging and etching without modification. Engineering review and material preparation moved quickly into solder mask application, delivering clean green coverage and white silkscreen registration across the compact boards.
HASL Lead Free surface finish was applied through precise molten solder coating and hot air leveling, producing a flat, uniform coating suited to standard assembly requirements. Because impedance control was not required, stackup remained at the default configuration, eliminating extra verification steps while still ensuring layer-to-layer registration stayed within tolerance.
All five boards completed full electrical testing with 100 % continuity and isolation compliance. The complete sequence from material cut to final inspection took 1.5 days, resulting in a small batch of consistent, ready-to-use 2-layer FR4 PCBs delivered on schedule.
This order also received positive feedback from the customer regarding the consistent quality and reliable delivery. View the full customer review→
