Manufacturing Summary
These 75 single-layer aluminum PCBs measured 30 × 648 mm with 1.6 mm thickness, 1 oz copper, and 1.0 W/mK thermal conductivity. The elongated form factor required careful metal base preparation and thermal insulation lamination to maintain flatness and ensure reliable heat dissipation across the full length. With 10/10 mil track spacing, 1.5 mm minimum holes, and AC2500V voltage withstand, the design followed conventional geometry yet demanded precise registration during circuit imaging and etching on the aluminum substrate.
White solder mask and black silkscreen were applied after lamination, followed by molten solder coating and hot air leveling to produce a uniform HASL Lead Free finish. Heat dissipation control steps preserved the thermal path while meeting the voltage specification. All boards underwent full electrical testing, confirming continuity and isolation across the entire batch.
The order was completed in 6.3 days from engineering review through final testing. This production run demonstrates consistent execution for narrow, extended aluminum PCBs where thermal management and dimensional stability are critical.
