MCPCB, Metal Core PCB, Thermal PCB

 
 
 

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:

  • Aluminum thickness: 0.8-2.0mm

  • Thermal conductivity: 1.5W/(m·K) and 2.0W/(m·K).

  • Peeling strength: >9lb/in

  • Solder resistance: SF: 288℃, >180 sec.

  • Breakdown voltage: >3000v

  • Dielectric loss angle: 0.03

  • Flammability: UL 94V-0

There can be cost savings using a metal PCB in high-heat dissipating applications such as LED lighting and communications electronic equipment.
