For this order of 15 2-layer FR4 PCBs, production centered on boards measuring 56 × 88 mm with standard 1.6 mm thickness, 1 oz copper weight, and conventional 6/6 mil trace spacing. Minimum hole size of 0.3 mm and the absence of impedance control allowed straightforward processing while still demanding consistent registration and plating quality. Green solder mask with white silkscreen completed the stackup, paired with HASL Lead Free surface finish to ensure reliable solderability for customer assembly.
Engineering review and material preparation were followed by precise circuit imaging and etching to maintain uniform copper features. Solder mask application was carefully timed before the molten solder coating and hot air leveling steps that produce even HASL coverage across all pads. Each board then received full electrical testing to confirm net continuity and isolation.
The complete run finished in 2.7 days with stable process parameters throughout the batch, resulting in uniform surface quality and dimensional accuracy. This execution reflects dependable handling of standard double-sided FR4 PCB specifications from start to delivery.
This order also received positive feedback from the customer regarding the consistent quality and reliable delivery. View the full customer review→
