Manufacturing Summary
This production record covers 20 single-sided 1-layer FR4 PCBs, each a compact 25 x 25 mm square built to 1.6 mm thickness and 1 oz copper weight. The design used standard 6/6 mil track and spacing with minimum 0.3 mm holes and omitted both soldermask and silkscreen entirely. We applied HASL Lead Free finish directly to the etched copper to ensure reliable solderability while keeping the process aligned with the bare-board requirements.
Execution followed a focused sequence of engineering review, material preparation, circuit imaging and etching. Molten solder coating and hot air leveling produced a uniform surface across all features, after which every board received electrical testing to confirm continuity. The simplified construction removed several coating steps, allowing steady progress without deviation from the specified parameters.
The order was completed in 2.2 days, yielding consistent boards that match the customer’s exact needs for a basic single-layer circuit. Each unit left the line with clean edges, level HASL coverage, and verified electrical performance suitable for straightforward assembly.
