Thermal Dissipation:the performance of aluminum PCBs while
dissipating heat is quite well as compared to ordinary FR4 PCBs.
For example, a FR4 PCB that is 1.5mm thick will have thermal
resistance of 20-22 degrees per watt whiles a aluminum PCB 1. 5mm
thick will have a thermal resistance of 1-2 degrees per watt.
Thermal Expansion: each substance has its own coefficient of
thermal expansion. The CTE of aluminum (22ppm/C) and
copper(18ppm/C)is quite close. Since aluminum PCBs work well in
terms of Thermal dissipation they do not have severe expansion or
contraction issues. They work excellently and are durable and
reliable.
Dimensional Stability: aluminum PCBs show dimensional stability and
stable size. For example, when they are heated from 30-140 degrees,
their size only had a change by 2.5%-3.0%.
Others: Aluminum PCBs can be used in power device surface mount
technology. They are effective for use in circuit design because of
their performance in terms of thermal expansion of circuit design.
They help to prolong products shelf life and product power density.
They are also extremely reliable. They can help to shrink the
overall volume of the product and is also a cheaper option. They
show electromagnetic shielding and high dielectric strength.
Classification of Aluminum PCBs: Aluminum PCBs are essentially
divided into three categories.
1: Universal Aluminum PCB: the dielectric layer used here is made
up of epoxy glass fiber pre-preg.
2: High Thermal-Conductive Aluminum PCB:the dielectric layer is
made up of epoxy resin. The resin used must have high thermal
conductivity.
3: High-frequency Aluminum PCB:the dielectric layer is composed of
polyolefin or polyimide resin glass fiber pre-preg.
