Metal Core PCB

A metal core PCB, also called a thermal PCB or MCPCB, differs from the traditional FR4 printed circuit boards in that it incorporates a metal material as its base. With a thermally conductive dielectric layer, the prepreg dielectric ensures that heat is transferred to the base plate. The base plate, usually made of aluminum or copper, in turn, offers mechanical integrity while transferring the heat to the mounting surface or to the air.

Metal core PCB ensures:

  • Proper thermal management
  • Improved product reliability
  • Improved mechanical durability

At Technotronix, we have been manufacturing metal core printed circuit boards for several industries. Our state-of-the-art facility along with our commitment to quality ensures that what you get are high-quality metal core PCBs that work well to dissipate heat.

The most important benefit of metal core printed circuit boards (MCPCB) is their ability to dissipate heat. With miniaturization becoming the order of the day and the constant expansion of component density, gradual increase of heat flow density is a reality.

The traditional thermal dissipation methods are not able to meet the demands of high-tech circuit boards, therefore necessitating a new kind of solution. PCB Metal Core ensures that components are not overheated. This helps in optimizing performance as also increasing the lifespan of its components.

In addition, typically where aluminum core PCB used, some of the other advantages include:

  • They help with higher levels of heat transfer. Also, they act as a heat sink for the design while allowing different components of the design to be interconnected.
  • Aluminum PCBs are a less expensive alternative.
  • Being non-toxic and recyclable, aluminium comes with its environment friendly benefits.
  • Being sturdy, it also reduces the possibility of accidental breakages.
  • It is lightweight and adds strength and resilience.

A Metal Core Printed Circuit Board also known as a thermal PCB or metal backed PCB, is a type of PCB that has a metal material as its base to help dissipate heat.

The biggest difference between the two lies in terms of thermal conductivity. While MCPCB has higher thermal conductivity, ranging from 1.0W-4.0W, FR4 PCB has low thermal conductivity, usually around 0.3W.

The most important benefit of metal core printed circuit board is its ability to dissipate heat. With components that aren’t overheated, performance is optimized.

We are equipped to offer Aluminum, Copper, Steel, Stainless steel, and Iron Alloy as base material.

The metal core is not enough to heat transfer, there is an insulated conductor between copper layers & Metal core, we call it dielectric layer.
