For this order of five 2-layer FR4 PCBs measuring 67.31 x 47 mm, we executed the production sequence according to the 1.6 mm board thickness, 1 oz copper weight, and conventional 6/6 mil track spacing. The minimum hole size of 0.3 mm fit within standard drilling capabilities, allowing engineering review and material preparation to flow directly into circuit imaging and etching.
Green solder mask and white silkscreen were applied to deliver clear component identification before the HASL Lead Free surface was formed through molten solder coating and hot air leveling. Electrical testing then verified continuity and isolation on each board, confirming full compliance with the default stackup and design.
The manufacturing concluded successfully within 2.1 days. This production run of standard single PCBs without impedance control resulted in five consistent boards that met all specified parameters from initial material to final inspection.
This order also received positive feedback from the customer regarding the consistent quality and reliable delivery. View the full customer review→
