2 Layer Aluminum PCB Production Record #ALU-20250828-0085

For this order, five single 2-layer aluminum printed circuit boards were produced to dimensions of 56 × 71.9 mm and 1.6 mm thickness. The boards were built with 1 oz copper, 2.0W thermal conductivity, 10/10 mil track and spacing, and 1.5 mm minimum hole size. Black soldermask, white silkscreen, HASL Lead Free surface finish, and AC2500V voltage withstand were implemented exactly as specified, with the aluminum base selected to support consistent heat dissipation in compact assemblies.

Manufacturing followed a sequence of metal base preparation, circuit imaging and etching, and thermal insulation lamination to maintain the dielectric layer integrity. We applied solder mask, performed molten solder coating, and used hot air leveling to produce a uniform HASL Lead Free coating. Thermal control steps were integrated after lamination to preserve the 2.0W thermal performance without introducing stress to the aluminum substrate.

Electrical testing verified that all five boards met the required insulation and continuity standards. The completed Aluminum PCBs delivered stable thermal and electrical characteristics suited for applications needing reliable heat transfer in limited spaces.
