Manufacturing Summary
This batch of 20 compact 2-layer FR4 PCBs measured 43 × 43 mm with standard 1.6 mm thickness and 1 oz copper weight. Minimum 6/6 mil track spacing and 0.3 mm hole size placed the design within conventional parameters, requiring no blind vias or impedance control. Green solder mask, white silkscreen, and HASL Lead Free surface finish completed the build, calling for straightforward material preparation and process sequencing that matched the small single-board format.
We performed engineering review, circuit imaging and etching, followed by solder mask application. Molten solder coating and hot air leveling produced a uniform lead-free surface, after which every board underwent electrical testing. The uncomplicated stackup and modest quantity allowed the full sequence to finish in 2.2 days while maintaining feature accuracy and copper integrity across the run.
Resulting boards showed dimensional stability and consistent PCB solderability in testing, confirming that the chosen processes aligned precisely with the stated specifications. Delivery of these standard 2-layer FR4 PCBs with HASL Lead Free provided the customer with reliable parts ready for assembly.
This order also received positive feedback from the customer regarding the consistent quality and reliable delivery. View the full customer review→
