Aluminum PCB performance:
1. Heat dissipation
Compared to normal FR4 PCBs, the aluminum PCBs perform better and more quickly in heat dissipation. Take the FR4 PCB and the aluminum PCB with the same thickness of 1.5mm as an example. FR4 PCBs have a thermal resistance of from 20°C/W to 22°C/W while aluminum PCBs have it of from 1°C/W to 2°C/W, which proves the feature again.
2. Thermal expansion
The thermal expansion and contraction are common properties of substances but have different coefficients. Because of the excellence in heat dissipation of the aluminum PCBs, the problems on the thermal expansion and contraction on the board surface will be significantly reduced to increase the durability and reliability of the entire equipment and electronic devices. This kind of advantages can be particularly suitable for the thermal expansion and shrinkage problems of surface mount technology (SMT).
3. Dimensional stability
The aluminum PCBs have significantly stable dimensions. Their dimensions will only change about 2.5% to 3.0% when they are heated from 30 ℃ to 140 ℃ or even 150 ℃.
4. Other performance
a. Applicability to power device SMT.
b. Effective thermal expansion of circuit design.
c. Helpful to reduce operating temperature, improve product power density and reliability, and extend the shelf life of products.
d. Helpful to reduce the size of the product, hardware and assembly costs.
e. Easy replacement of fragile ceramic substrates with better insulation performance and mechanical durability.
