　　What is Aluminum PCB?

　　An aluminum PCB has a similar layout to Normal PCB. It has a caste or layers of bull, solder mask and silkscreen concentrated over it. Rather of having a fiberglass or plastic substrate, still, an aluminum circuit board has a substance substrate. This base mainly contains a combination of aluminum. The substance core can correspond entirely of substance or have a combination of fiberglass and aluminum. Aluminum PCBs generally are single sided, but can be double sided as well. Mulilayer Aluminum PCBs are largely delicate to manufacture.

　　Performance of Aluminum PCB

　　1. Thermal Dissipation

　　Common PCB substrates, analogous as FR4, CEM3 are poor driversofthermal.However, it will affect in high temperature failure of electronic factors, If the heat of electronic paraphernalia can't be distributed in time. Aluminum substrates can break this thermal dissipation problem.

　　2. Thermal Expansion

　　Aluminum substrate PCB can effectively break the thermal dissipation problem, so that the thermal expansion and contraction problem of factors on published circuit boards with different substances can be soothed, which improves the durability and responsibility of whole machine and electronic paraphernalia. In particular, aluminum substrate can break the SMT ( face mount technology) thermal expansion and contraction problems.

　　3. Dimensional Stability

　　Aluminum substrate published circuit board has apparently advanced stability than the separating material of the published circuit board. When toast from 30 ° C to 140

　　150 ° C, the dimensional change of aluminum substrate is only2.5~30%

　　4. Other Performance

　　Aluminum substrate published circuit board has shielding effect, and can necessary brittle ceramic substrate. Aluminum substrate also helps to meliorate the heat resistance and physical parcels and reduce product costs and labor.
