Single Layer Aluminum PCB Production Record #ALU-20260920-088

This production record covers ten panelized single-layer Aluminum PCBs measuring 142 × 202 mm with 1.6 mm thickness and 1 oz copper on a 1.0 W/m·K thermally conductive base. The design called for 10/10 mil track spacing, 1.5 mm minimum holes, white soldermask, black silkscreen, and AC2500V voltage withstand. These parameters suited conventional single-layer metal-core fabrication while emphasizing heat dissipation performance.

Manufacturing began with metal base preparation and circuit imaging followed by etching to define the copper pattern. Thermal insulation lamination bonded the dielectric layer without compromising conductivity. White soldermask and black legend were applied, then the HASL Lead Free surface finish was formed through molten solder coating and hot air leveling to produce a flat, uniform coating across the aluminum PCB panels.

Heat dissipation control steps and complete electrical testing verified thermal and dielectric integrity. The entire order was completed in 2.1 days, delivering consistent panels that satisfied all dimensional, thermal, and electrical requirements for reliable field performance.

This order also received positive feedback from the customer regarding the consistent quality and reliable delivery. View the full customer review→
