This production record covers five units of a 2-layer FR4 PCB, each measuring 84.33 × 127.76 mm with a standard 1.6 mm thickness and 1 oz copper weight. The design featured a 10 mil track and spacing, which aligns with conventional manufacturing parameters, along with 0.5 mm minimum hole size. No impedance control was required, allowing established procedures to be followed from engineering review through material preparation and circuit imaging to etching.
Matte green solder mask was applied uniformly before white silkscreen printing to satisfy the specified appearance. The HASL Lead Free surface finish was executed through molten solder coating and hot air leveling, delivering consistent pad coverage suited to both the board dimensions and hole sizes. Custom stackup parameters received close attention during lamination to maintain flatness and copper integrity across the small batch.
Electrical testing verified continuity and isolation on every board. The entire order moved from start to completion in 1.7 days, resulting in five reliable 2-layer FR4 PCBs with HASL Lead Free finish that matched all dimensional and finish requirements.
This order also received positive feedback from the customer regarding the consistent quality and reliable delivery. View the full customer review→
