Printed circuit boards (PCBs) are found in various electronics, from LED lights to high-tech scanners. Due to varying conductivity, insulation, and longevity requirements, PCBs are manufactured using a wide array of materials. Unlike standard PCBs, which typically use an FR-4 fiberglass substrate, aluminum PCBs are made using a metal substrate primarily comprised of aluminum alloy.
Metal Core PCB
The most critical step is choosing the proper manufacturer. Every manufacturer has a limited capability of manufacturing PCBs. The manufacturer should be able to provide what you need. There are a limited number of layers, thickness ranges, types of materials, Tg range, conductivity ranges, etc.
