What Are Aluminum PCBs?
They are PCBs that have a layer or layers of silkscreen, solder mask, and copper coat. Also, these aluminum PCBs come with metal substrates instead of a plastic substrate or fiberglass material.
The base material of aluminum PCB comes with the regular FR4 and an aluminum core. Also, aluminum PCBs are usually an ideal solution for tight-tolerant and high-power devices.
Hence, the PCB comes with a thermal layer that is clad and efficiently dispels heat. In summary, aluminum PCB’s presence helps to cool down components and increases electronic devices’ performance.
Why Aluminum Is a Great Unit for Circuit boards?
The reason is simple!
Aluminum is ideal for dissipating heat from essential electronic components, and it helps to minimize any detrimental effects that may occur on the PCB.
Also, aluminum material offers great durability and strength to electronic appliances, which fiberglass and ceramic bases cannot handle.
The Performance Scope of Aluminum PCBs
The Build Layout of Aluminum PCB
The structure or assemblage of aluminum PCBs comprises of four layers, namely:
The Types of Aluminum PCBs
Flexible Aluminum PCBs
Through-hole Aluminum PCBs
Multilayer Aluminum PCBs
The multilayer aluminum PCBs make up multilayers of dielectric materials that have thermal conductive characteristics.
Therefore, these aluminum PCBs are great heat dissipation agents designed for sophisticated solutions.
Hybrid Aluminum PCBs
What is the Production Process of Aluminum PCBs?
The production process of aluminum PCBs involves a thin dielectric layer that’s an electric insulator. But this insulator gets laminated between the metal base and copper foil.
Then, the copper foil gets etched into a PCB pattern, and the metal base extracts heat.
