Manufacturing Summary
These five single-layer aluminum PCBs were produced as large square panels measuring 438.56 × 438.56 mm, with 1.6 mm thickness, 1 oz copper, and a 1.0 W thermal conductivity base. The design specified 10/10 mil trace and spacing, minimum 1.5 mm holes, white soldermask, black silkscreen, and OSP surface finish while meeting AC 2500 V withstand requirements. This combination demanded careful attention to the aluminum substrate and dielectric layer to maintain both heat dissipation and electrical isolation.
Metal base preparation and thermal insulation lamination were performed with tight thickness control to ensure consistent thermal transfer and dielectric strength across the large panel area. Standard circuit imaging and etching matched the conventional geometry, followed by uniform white solder mask application and OSP organic coating to protect the copper traces. Heat dissipation parameters received specific process monitoring throughout to prevent warping or delamination on the sizable boards.
Electrical testing confirmed full compliance with voltage withstand, continuity, and thermal performance. The complete order was delivered in 5.2 days, providing reliable aluminum PCBs optimized for high-power thermal management applications.
