Aluminum PCB Performance:
Before is the performance of the aluminum Printed Circuit Board.
Thermal Dissipation
There is no denying that aluminum PCB performs efficiently in terms
of thermal dissipation. These Printed Boards have the capability to
dissipate heat effectively in comparison to the regular Printed
Board.
Let us take an example to further demonstrate our point. Take
Aluminum Printed Board along with an FR4 Printed Circuit Board.
Both these boards have the same thickness i.e. 1.5mm. Despite
having the same thickness, Aluminum PCB would offer a thermal
resistance of 1°C/W to 2°C/W.
On the other hand, the standard Printed Circuit Board would offer
between 20°C/W to 22°C/W. This clearly illustrates that Aluminum
PCB is way ahead of the standard boards in case of thermal
dissipation.
Thermal Expansion
Contraction and thermal expansion are the nature of every
substance. However, the amount of expansion and contraction greatly
depends upon the material. There is a different thermal expansion
coefficient of every material.
Aluminum is an excellent choice in this regard as well. It works
smoothly for contraction and the thermal expansion problem of the
surface mount technology. These PCBs are completely reliable and
they increase the durability of the Printed Board.
After, thermal expansion is a great problem at the aluminum PCB
manufacturing end. Resolving this issue would make the Printed
Circuit Board robust.
Dimensional Stability
Aluminum PCBs ensure performance because they offer a stable size.
Even when you heat the Printed Circuit Board from 30°C up to 150°C
the expansion rate is between 2.5% to 3.0%.
