Along with manufacturing various types of PCBs, Stream PCB is a highly reputable metal core PCB manufacturer. In the electronics industry, metal core PCBs are also known as MCPCBs, metal-backed PCBs, or thermal PCBs. A basic metal core PCB design consists of a base metal layer that acts as a heat spreader.
We utilize a thick metal layer, typically aluminum or copper, on one side of the PCB. Depending on the design, the metal core is positioned either in the middle or on the back side of the board relative to the copper layer. The primary function of the metal core in an MCPCB is to efficiently dissipate heat away from heat-generating components, ensuring the protection of critical board elements.
The metal core transfers the extracted heat to a metal heat sink backing, providing superior thermal management. In metal core PCB designs, we use base metals as an alternative to traditional CEM3 or FR4 materials.

The primary benefit of metal core PCB design is superior thermal management. To enhance heat dissipation, we incorporate a dielectric polymer layer with high thermal conductivity between the metal core and the copper layer, reducing thermal resistance.
This advanced construction allows Stream PCB to manufacture metal core PCBs with significantly higher heat transfer rates. In fact, our metal core PCBs dissipate heat 8-10 times faster than standard FR4 PCBs. The metal core efficiently removes excess heat, keeping components cool, which in turn enhances board performance and extends its service life.
