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.
