This aluminum PCB production involved 10 boards of 65 x 632 mm dimensions on 1.0 mm thick substrate with 1.0W thermal conductivity. The single-layer circuits utilized 1 oz copper with standard 10/10 mil geometry, 1.5 mm minimum holes, black solder mask, white silkscreen lettering, and HASL Lead Free finish. The stack-up was engineered for AC 2500V voltage withstand, emphasizing thermal transfer capabilities.
Processes started with engineering review and metal base preparation to accommodate the narrow, elongated profile. Circuit imaging and etching preceded thermal insulation lamination of the dielectric layer to the aluminum. Subsequent steps included solder mask application, molten solder coating with hot air leveling for the lead-free surface, and integrated heat dissipation controls.
Electrical testing validated all parameters, resulting in uniform boards completed over 3.4 days. The execution ensured reliable performance for heat-dissipating, high-voltage assemblies.
