Manufacturing Summary
This order comprised 50 single-layer FR4 Panel PCBs measuring 157 × 276 mm, fabricated at 1.6 mm thickness with 1 oz copper. The design used conventional 10/10 mil track and spacing together with 0.8 mm minimum holes and required no soldermask or silkscreen. After circuit imaging and etching, we applied HASL Lead Free finish directly to the exposed copper traces, producing a uniform coating that supports reliable component attachment while respecting the bare-board specification.
Manufacturing followed a clear sequence beginning with engineering review of the custom stackup and material preparation. Circuit imaging and etching created the single-layer pattern, after which the panels moved through molten solder coating, hot air leveling, and full electrical testing. Each step was executed according to the absence of mask and legend layers, keeping process parameters matched to the straightforward geometry and 50-piece quantity.
The complete run finished in 2.5 days, delivering panels with consistent trace definition and surface finish across the batch. This execution reflects standard FR4 PCB handling adapted to the customer’s bare-copper requirements, ensuring the delivered boards met all dimensional and electrical criteria without added complexity.
