Black soldermask Aluminium PCB Circuit Layer

The circuit layer (commonly used electrolytic copper foil) is etched to form the printed circuit, Compared to FR4 material, Aluminium PCB can bear higher electric current when same thick circuit layer and same trace width.

Performance of Aluminum PCBs:

1. Dimensional Stability

Aluminum PCBs display dimensional stability & steady size. For example, when they are heated from 30-140 degrees, their dimensions only had a change by 2.5%-3.0%.

2. Thermal Dissipation

The performance of aluminum PCBs while dissolving heat is quite well as compared to ordinary FR4 PCBs. For example, a FR4 PCB that is 1.5mm thick will have a thermal resistance of 20-22 degrees per watt while an aluminum PCB 1.5mm thick will have a thermal resistance of approximately 1-2 degrees per watt.

3. Thermal Expansion

Every substance has its own coefficient of thermal expansion. The CTE of copper(18ppm/C) and aluminum (22ppm/C) is fairly close. Since aluminum PCBs work well in terms of Thermal dissipation, they do not have severe contraction or development issues. They work exceptionally and are durable plus reliable.
