Metal Core Circuit Board FAQs
1.What is the thickness of a metal core PCB?
The thickness of the metal core in a PCB substrate is typically 30 mil - 125 mil, but thicker and thinner boards are possible.
2.What are the advantages of metal core board?
Metal core boards transfer heat 8 to 9 times faster than FR4 PCBs. These metal core laminates keep heat-generating components cool by dissipating heat faster. The dielectric material is kept as thin as possible in order to create the shortest path from the heat source to the metal backplane.
3.How is a metal core PCB made?
If the board is a single-layer board with no layers transitioning back to the metal plate, the dielectric layers can be pressed and bonded to the metal plate using the standard process used with FR4 dielectrics
4.What is a metal core PCB?
A metal core printed circuit board (MCPCB) is a printed circuit board that contains base metal materials. The core is designed to transfer heat away from components that generate a lot of heat.
