This production record covers a batch of five 2-layer FR4 PCBs measuring 77.47 × 120.65 mm. Built to standard 1.6 mm thickness with 1 oz copper, the boards used a conventional 10/10 mil trace width and spacing together with 0.3 mm minimum hole size. These relaxed geometries and the absence of impedance control allowed straightforward processing on our default stackup while maintaining tight dimensional tolerances throughout etching and drilling.
Manufacturing followed a sequenced flow: engineering review, material preparation, circuit imaging and etching, green solder mask application, and white silkscreen printing. For the HASL Lead Free surface finish, molten solder coating and hot air leveling were precisely controlled to produce a uniform, oxidation-resistant finish suitable for standard assembly. Every board then received 100 % electrical testing to verify net continuity and isolation.
The complete order was finished in 1.4 days, yielding five consistent boards that met all specified parameters without deviation. This small-quantity run demonstrates reliable execution for standard 2-layer FR4 PCB designs using HASL Lead Free finish.
This order also received positive feedback from the customer regarding the consistent quality and reliable delivery. View the full customer review→
