An Aluminum PCB PCBA is a specialized printed circuit board assembly designed for high-power and high-thermal-performance applications, leveraging an aluminum core substrate for superior heat dissipation. These PCBAs feature 0.5–2 oz copper layers (18–70 µm) to handle currents in demanding environments like LED lighting systems and automotive power controllers. The aluminum core, typically made from Goldenmax GL11 or Guangzhou Aluminum alloys, ensures mechanical stability and thermal conductivity, while photosensitive soldermask and precise drilling (±0.1 mm tolerance) enable reliable manufacturing. With a thickness range of 0.8–2.0 mm and compliance with UL 94V-0 and RoHS, these boards are ideal for compact, high-efficiency designs requiring extended operational lifespans. Applications span renewable energy inverters, industrial motor drives, and consumer electronics, where heat management and durability are critical.
