2 Layer Aluminum PCB Production Record #ALU-20251014-0174

This production record covers 80 pieces of 2-layer aluminum PCBs delivered in panel format. Boards measure 30.1 × 49.91 mm with 1.6 mm total thickness, 1 oz copper, 10/10 mil minimum trace and spacing, and 1.0 mm minimum hole size. The aluminum base specified 1.0W thermal conductivity, white solder mask, black silkscreen, and HASL Lead Free finish while meeting AC 3000V voltage withstand requirements. These parameters called for careful balance between thermal transfer and dielectric integrity on every panel.

Manufacturing followed a sequenced flow of metal base board preparation, thermal insulation lamination, circuit imaging and etching, solder mask application, molten solder coating, and hot air leveling. Heat dissipation control steps were integrated after lamination to protect substrate flatness and conductivity. Each stage accounted for the aluminum core's expansion behavior, ensuring registration and surface quality remained within tolerance across the 17.6-day run.

Electrical testing confirmed isolation strength and continuity on all panels before release. The resulting aluminum PCBs provide consistent thermal performance and mechanical stability suited to power and lighting applications.
