What is Aluminum PCB?
An aluminum PCB has a similar layout to any other PCB. It has a layer or layers of copper, solder mask and silkscreen layered over it. Instead of having fiberglass or plastic substrate, though, an aluminum circuit board has a metal substrate. This base mainly contains a combination of aluminum. The metal core can consist entirely of metal or have a combination of fiberglass and aluminum. Aluminum PCBs typically are single-sided but can be double-sided as well. Multilayer Aluminum PCBs are highly difficult to manufacture.
Aluminum Substrate
Aluminum boards get the most use in LED and power converting electronics. The intense light produced by LEDs creates high levels of heat, which aluminum directs away from components. An aluminum PCB extends the lifespan of an LED device and provides more stability. You can find aluminum substrates in street lights, stop lights and household lighting. They allow power converters to change currents and regulate electronics. Creators in many other industries also find use in aluminum circuit boards, but they don't implement them as often.
