Manufacturing Summary
This production record covers a standard 4-layer FR4 PCB completed on 2025-12-05. The boards were built to 1.6 mm thickness with 1 oz copper on all layers, 6/6 mil minimum trace and spacing, and 0.3 mm minimum hole size. These conventional parameters allowed standard etching and plating sequences while requiring precise control during molten solder coating and hot air leveling to produce a uniform HASL Lead Free surface.
Engineering review verified all files before material preparation. Circuit imaging and etching established accurate layer patterns, followed by solder mask application with tight pad clearance. Batch AOI inspection, yield control management, and 100% electrical testing confirmed continuity and isolation across every panel. The entire manufacturing cycle finished in 2.3 days with no process deviations.
The finished batch showed consistent copper thickness, solder coverage, and dimensional stability, delivering boards that meet assembly requirements without additional tuning.
