This production record covers a batch of five 2-layer FR4 PCBs manufactured as individual boards. With 1.6 mm thickness, 1 oz copper, and standard 6/6 mil trace width and spacing, the design presented conventional geometry that we processed without complication. The chosen HASL Lead Free surface finish, green soldermask, and absence of silkscreen printing further defined the manufacturing approach for these compact 12.1 x 8.2 boards.
Following an initial engineering review, material preparation matched the custom stackup requirements. Circuit imaging and etching delivered clean copper features, after which solder mask application provided the specified green coverage. We then performed molten solder coating and hot air leveling to achieve an even, reliable surface finish known for good solderability.
Comprehensive electrical testing ensured each of the five boards met all performance criteria before shipment. Completed over 4.5 days, the order demonstrates consistent execution for standard 2-layer FR4 PCB builds with HASL Lead Free finishing.
This order also received positive feedback from the customer regarding the consistent quality and reliable delivery. View the full customer review→
