Manufacturing Summary
This production batch comprised 20 aluminum PCBs built as panels, each featuring 2-layer circuitry on a 3 mm thick base with 2.0 W/mK thermal conductivity. Measuring 93 × 142.4 mm and carrying 2 oz copper, the boards used a conventional 10/10 mil track and spacing geometry together with large 1.5 mm minimum holes. After engineering review and metal base preparation, the sequence progressed through circuit imaging, thick copper electroplating, controlled etching, and thermal insulation lamination to preserve both electrical isolation and heat-transfer performance while meeting the AC 2500 V withstand requirement.
White solder mask, black silkscreen, and OSP organic coating were applied with close attention to surface uniformity, ensuring solderability without compromising the aluminum core's dissipation characteristics. Heat dissipation control measures and final electrical testing confirmed consistent thermal and dielectric behavior across all panels. The 20-day schedule accommodated the necessary curing and verification steps inherent to thick aluminum constructions, delivering stable quality without deviation from specified parameters.
