Manufacturing Summary
This production record covers five units of 2-layer FR4 PCBs, each with dimensions of 185 x 245 mm, 1.6 mm board thickness, and 2 oz copper weight on both layers. The heavier copper on this conventional 6/6 mil geometry required thick copper electroplating and controlled copper etching to maintain accurate trace profiles and reliable plating in the 0.5 mm holes without compromising edge definition.
After circuit imaging, green solder mask and white silkscreen were applied, followed by molten solder coating and hot air leveling to produce a uniform HASL Lead Free surface. With default stackup and no impedance control specified, the process sequence remained straightforward yet demanded close attention to copper distribution across the relatively large board size and limited five-piece quantity.
Electrical testing confirmed full continuity and isolation on every board. The complete cycle from engineering review to final inspection was completed in 1.4 days, delivering boards that met all specified parameters for this 2 oz copper configuration.
