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 thermoelectric separation copper based PCB:

1. Apply to copper base, for based PCB, there is a high density and has a strong thermal load carrying ability and great heat conduction and heat dissipation.

2. Use the thermoelectric separation structure, and is in contact with zero thermal resistance to the lamp bead. So it can prevent the attenuation of lamp bead light from reducing and extend lamp life.

3. For copper base, it has a high density and great thermal load carrying ability, as well as smaller size at the same power.

4. Suitable for matching single high power lamp bead, especially COB package so that make a better effect.

5. It can do various surface finish based on different demands, such as immersion gold, OSP, hot air soldering leveling (HASL), silver plating, immersion silver + silver plating, there has a great reliability on the layer of surface finish.

6. It can make different structure according to different design needs of the lamps, such as copper bumps, copper concave block, the parallel thermal layers and circuit layers.

The disadvantages of thermoelectric separation copper based PCB:

It is not suitable for packaging with single electrode chip bare crystal.

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.
