2 Layer Aluminum PCB Production Record #ALU-20251014-0010

This production record covers 50 units of 2-layer Aluminum printed circuit board arranged in panels. Measuring 197.91 by 113 millimeters and 2 millimeters thick, these boards utilize a 2.0W thermal conductivity aluminum substrate with 1oz copper layers. The design employs a standard 10/10 mil minimum track and spacing, large 1.5 mm holes, white soldermask over black silkscreen, and HASL Lead Free finish. Specified to withstand AC 2500V, the configuration prioritizes effective thermal management without blind vias.

During manufacturing, we conducted detailed engineering review and aluminum material preparation before metal base preparation and thermal insulation lamination. Subsequent steps included circuit imaging and etching, solder mask application, and surface finishing via molten solder coating combined with hot air leveling. Heat dissipation control was maintained throughout, culminating in full electrical testing to confirm performance.

The 18.2-day production cycle permitted careful attention to each process, resulting in reliable Aluminum PCBs that consistently meet the thermal conductivity and high-voltage requirements of the application.
