Manufacturing Summary
Five 2-layer FR4 PCBs were fabricated in a single-board configuration, each measuring 103.65 x 115.06 mm with standard 1.6 mm thickness and 1 oz copper layers. The 6/6 mil minimum trace and spacing combined with 0.3 mm PCB via sizes represented conventional parameters that integrated seamlessly with our established imaging and etching processes. Material preparation and engineering review confirmed compatibility without requiring any design modifications.
Green solder mask and white silkscreen were applied prior to surface finishing with HASL Lead Free. This involved precise molten solder coating followed by hot air leveling to achieve uniform coverage across all pads. Full electrical testing verified connectivity and isolation on every board, supporting reliable performance for the small five-piece quantity.
The production cycle concluded successfully in 2.5 days, delivering consistent results aligned with the default stackup and standard specifications of this order.
This order also received positive feedback from the customer regarding the consistent quality and reliable delivery. View the full customer review→
