Performance of Aluminum PCB: 

1.  Thermal Dissipation

Common PCB substrates, such as FR4, CEM3 are poor conductors of thermal. If the heat of electronic equipments cannot be distributed in time, it will result in high temperature failure of electronic components. Aluminum substrates can solve this thermal dissipation problem.

2.  Thermal Expansion

Aluminum substrate PCB can effectively solve the thermal dissipation problem, so that the thermal expansion and contraction problem of components on printed circuit boards with different substances can be alleviated, which improves the durability and reliability of whole machine and electronic equipments. In particular, aluminum substrate can solve the SMT (surface mount technology) thermal expansion and contraction problems.

3.  Dimensional Stability

Aluminum substrate printed circuit board has apparently higher stability than the insulating material of the printed circuit board. When heated from 30 ° C to 140 ~ 150 ° C, the dimensional change of aluminum substrate is only 2.5 ~ 3.0%.

4.  Other Performance

Aluminum substrate printed circuit board has shielding effect, and can alternative brittle ceramic substrate. Aluminum substrate also helps to improve the heat resistance and physical properties and reduce production costs and labor.
