These five single-layer Aluminum PCBs measured 20.25 × 1168.4 mm with 1.6 mm thickness, 1 oz copper, and 3.0W thermal conductivity. The extreme length-to-width ratio demanded careful material handling and flatness control during metal base preparation and thermal insulation lamination. Specified at 10/10 mil track spacing and 1.5 mm minimum hole size, the design followed conventional geometry yet incorporated AC 3000V voltage withstand, white solder mask, black silkscreen, and HASL Lead Free finish.
Production began with targeted engineering review of the aluminum substrate and dielectric bonding requirements. After circuit imaging and etching, the thermal insulation layer was laminated under controlled pressure to preserve heat dissipation properties. Solder mask application was followed by molten solder coating and hot air leveling, with heat dissipation control steps maintained throughout to prevent warping on the long boards.
Electrical testing verified insulation resistance and thermal performance across all five boards, confirming full compliance with the high-voltage specification. The order was completed in 6.8 days, delivering consistent Aluminum PCB quality matched to the customer’s linear thermal management application.
