A simple metal core PCB is a single sided PCB layout bonded to a sheet of metal (usually aluminum, or copper alloy). A non-conducting dielectric layer separates the copper traces and components from the sheet metal. Soldermask gets applied over the top for PCB assembly.
There are a few advanced metal core PCB options available:
- COB MCPCB known as “Chip-On-Board” Metal Core PCB, is a type of MCPCB used in thermoelectric separation applications.
- Two layer MCPCB consists of a two layer circuit glued to one side of the metal core. Imagine a single-sided 2 layer flex board glued to a piece of metal.
- Multi layer MCPCB consists of a multi layer circuit glued to one side of the metal core. Imagine a multi layer flex board glued to a piece of metal.
- Double sided MCPCB is when you need parts on both sides
Check below parameters about our aluminum pcb material:
