What is Metal Core PCB?
PCBs are used in almost every industry, so there are different types of PCBs available according to the requirements.
Nowadays, many applications require quick heat dissipation, high mechanical strength, and shape retainment in the PCB.
All these features can be found in the metal core PCB.
Metalcore PCBs are the best when it comes to heat dissipation.
They have gained a lot of importance because of their heat dissipation feature.
They can quickly dissipate the heat, which increases the components’ lives and protects them from thermal stress.
Today, metal core PCBs are widely used, especially in LED lighting and high-frequency applications.
There are commonly three types of metal core PCBs; aluminum core PCB, iron core PCB, and copper core PCB.
These are used for different purposes, but the best of all is the copper core PCB.
It is the most expensive metal core PCB, and it offers optimum performance.

The rules you need to know when you design the copper based PCB
The minimum drilling diameter needs to be 0.4mm because of thicker copper base, the thickness of copper foil on the copper based PCB determine how the line width and spacing are, if the copper foil is thicker, it will need more wider line width and larger minimum spacing.

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.
