Metal Core PCB

MCPCB, Metal Core PCB, thermal PCB, whichever name you prefer, they are all boards which use a base metal material as the heat spreader portion of the circuit board.
Base metals in the MCPCB are used as an alternative to FR4 or CEM3 boards for the ability to dissipate heat away from critical board components and to less crucial areas such as the metal heatsink backing or metallic core.

As the leading metal core PCB manufacturer, we know, that the metal core of the thermal PCB can be aluminum (aluminum core PCB), copper (copper core PCB) or a mixture of special alloys. The most common is an aluminum core PCB.The thickness of metal cores in PCB base plates is typically 30 mil - 125 mil, but thicker and thinner plates are possible. MCPCB copper foil thickness can be 1 - 10 oz.

Metal Core PCB Advantages

The metal PCB uses the base metal material inside the circuit board for heat dissipation—the basic materials used for full heat dissipation of board components in the metal core PCB. Metalcore PCBs are capable of quicker transfer of heat from 8 to 9 than the FR4. A better choice than a normal PCB is the metal core or IMS (Insulated Metallic Substrate). These PCBs are ideal for large mechanical loads, and applications such as LEDs are produced at high temperatures. The cooling unit is built into a circuit board to save energy. A large amount of heat is produced by certain applications, and the fans are sufficient for it. For metal core PCBs, the conductive cooling solution is more preferred.

Through supplying aluminum and copper base PCBs with leading heat dissipation technology, Viasion has worked on thousands of metal core PCB projects. Viasion is the best place for your PCB metal core requirements; with our 100% guarantee of efficiency, we trust thousands of electronic engineers around the world.
