An Aluminum PCB, alsoknown as an Aluminum-Based PCB or Metal Core PCB (MCPCB), uses an aluminum baseinstead of a conventional FR-4 substrate.
Its structure typicallyincludes a copper circuit layer, a thermally conductive dielectric layer and analuminum base. The metal base transfers heat away from electronic componentsmore efficiently, making this PCB suitable for power and heat-generating applications.
Aluminum PCBs provideelectrical connections while helping transfer and dissipate heat from powercomponents.
Depending on thedesign, they can support:
Heat dissipation
Power conversion and regulation
Motor and actuator control
High-power LED operation
Power-device mounting
Stable operation under thermal loads
Improved thermal management
Compact power-module design
