Manufacturing Summary
This production record covers a batch of 20 single 2-layer FR4 PCBs, each measuring 44.8 mm by 57 mm. Built to a standard 1.6 mm thickness with 1 oz copper weight, the design used 6/6 mil minimum track and spacing together with 0.3 mm minimum hole size. The combination of matte black soldermask and white silkscreen produced a clean, high-contrast appearance while HASL Lead Free surface finish delivered reliable solderability for PCB assembly.
We performed an engineering review to confirm all parameters before material preparation and precise circuit imaging and etching. Solder mask application received specific attention to achieve the required matte texture without affecting registration. Molten solder coating and hot air leveling created an even HASL Lead Free layer across the pads, after which full electrical testing verified continuity and isolation on every board.
The entire order moved through production in 1.5 days with steady process control, yielding consistent thickness, finish quality, and dimensional accuracy. Execution focused on matching the customer's visual and functional requirements for these standard 2-layer FR4 PCBs while maintaining dependable delivery.
