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 advantages of copper based PCB

Comparing to aluminum PCB, copper based PCB has a great thermal conductivity which is the twice higher than aluminum PCB, the higher thermal conductivity is, the higher heat conduction is, as well as the better heat dissipation is.

And copper base can be plated though hole but aluminum base can not, however, it needs to be the same for the network of plated through hole so that the signal has a great grounding property, still, the copper has the solderability to mount and solder the structural component of design in the end.

What’s more, the copper base on the copper based PCB can etch a great drawing, there will a boss shape after processing, which is good for component, needless to say, the component can be directly pasted on the boss so that make a great effect on good grounding and heat dissipation.

Because there is a different modulus of elasticity between copper and aluminum, such as for copper, its modulus of elasticity is about 121000MPa, but aluminum is about 72000MPa, and the warping and shrinking of copper based PCB is smaller than aluminum PCB, which has a more stable property.

● Low thermal resistance and high pressure resistance

● Excellent dimensional stability

● good heat dissipation

● Non-magnetic

● High mechanical strength

● Good viscoplastic property

● Ability to withstand thermal aging

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.
