This production record covers five single 2-layer FR4 PCBs measuring 165.1 × 118.11 mm with standard 1.6 mm thickness and 1 oz copper weight. An engineering review verified all parameters before material preparation and circuit imaging and etching established the 6/6 mil traces and 0.3 mm minimum holes. Because the geometry fell within conventional tolerances and impedance control was not required, the process moved steadily without special routing or stackup adjustments.
Green solder mask and white silkscreen were applied, followed by molten solder coating and hot air leveling to produce a uniform HASL Lead Free finish on every board. Electrical testing then confirmed continuity and isolation across all five pieces. The default stackup and straightforward specifications supported consistent plating and surface quality throughout the 1.5-day schedule.
Completed boards met all dimensional and electrical criteria, providing reliable performance for the customer’s low-volume requirement. The execution demonstrates repeatable results for standard FR4 PCB orders finished with HASL Lead Free.
This order also received positive feedback from the customer regarding the consistent quality and reliable delivery. View the full customer review→
