This production record covered five single 2-layer FR4 PCBs measuring 110 × 171.5 mm with standard 1.6 mm thickness and 1 oz copper weight. The design used conventional 6/6 mil trace and spacing, 0.4 mm minimum holes, green solder mask, white silkscreen, and HASL Lead Free surface finish. Without impedance control or special stackup requirements, the build focused on straightforward execution and repeatable surface quality for this small-quantity order.
After engineering review and material preparation, circuit imaging and etching created clean, uniform traces suited to the standard geometry. Solder mask application was followed by molten solder coating and hot air leveling to produce an even, solderable HASL Lead Free finish. Every board then completed full electrical testing to verify net continuity and isolation.
The complete run finished in 2.2 days, yielding five consistent boards that met all dimensional and performance criteria. This order shows reliable processing of standard 2-layer FR4 PCB requirements with short turnaround and stable results from etching through final test.
This order also received positive feedback from the customer regarding the consistent quality and reliable delivery. View the full customer review→
