Manufacturing Summary
This order comprised ten single-sided Aluminum PCBs with elongated dimensions of 20 × 722 mm, built on a 1.6 mm substrate with 1.0W thermal conductivity and 1 oz copper. The design combines effective heat dissipation with AC2500V voltage withstand capability, paired with white soldermask and black silkscreen. These choices required specific attention during material preparation and surface treatment to maintain thermal performance and coating uniformity on the metal base.
Manufacturing followed a sequence of metal base preparation, circuit imaging and etching to meet the 10/10 mil track spacing, thermal insulation lamination, and solder mask application. HASL Lead Free surface finish was achieved through molten solder coating and hot air leveling, while dedicated heat dissipation control steps preserved the aluminum core properties. Minimum hole size of 1.5 mm simplified drilling yet demanded accurate registration across the long boards.
Electrical testing verified dielectric strength and continuity on every unit. The complete run finished in 3.8 days, resulting in consistent boards that satisfy the thermal and high-voltage requirements without deviation from specified parameters.
