We produced 20 units of 2-layer FR4 PCBs measuring 60 × 80 mm with standard 1.6 mm thickness and 1 oz copper. The 4/4 mil minimum trace and spacing combined with 0.4 mm holes required precise circuit imaging and etching to maintain edge definition and avoid shorts on this tighter geometry. Material preparation and custom stackup verification were completed first, followed by solder mask application using green ink and white silkscreen.
HASL Lead Free surface finish was formed through molten solder coating and hot air leveling, delivering a consistent, flat coating across all boards. Full electrical testing verified continuity and isolation on every piece, confirming that the batch met all specified tolerances without rework. The entire sequence from engineering review to completion took 4.1 days.
This small single-PCB run focused on controlled execution of standard processes around the finer 4/4 mil features, resulting in uniform quality and reliable solderability for customer assembly.
This order also received positive feedback from the customer regarding the consistent quality and reliable delivery. View the full customer review→
