MCPCB, Metal Core PCB, thermal PCB - whichever name you prefer, they are all PCBA boards which use a base metal material as the heat spreader portion of the KingshengPCBA circuit board.

Base metals in the MCPCB are used as an alternative to FR4 or CEM3 PCB boards for the ability to dissipate heat away from critical PCB board components and to less crucial areas such as the metal heatsink backing or metallic core.

Metal Core PCB board Materials and Thickness

The metal core of the thermal PCB can be aluminum (aluminum core PCB), copper (copper core PCB?or a?heavy copper 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 PCB thicker and thinner plates are possible.

Advantages of Kingsheng MCPCB

MCPCBs can be advantageous to use for their ability to integrate a dielectric polymer layer with a high thermal conductivity for a lower thermal resistance.

MCPCBs are used instead of traditional FR4 or CEM3 PCBs because of the ability to efficiently dissipate heat away from the PCB components. This is achieved by using a Thermally Conductive Dielectric Layer.

Metal core PCBs transfer heat 8 to 9 times faster than FR4 PCBs. MCPCB laminates dissipate heat, keeping heat generating PCB components cooler which results in increased performance and life.

Metal Core PCB uses - LED Applications and More

Applications that generate a large amount of heat often cannot be adequately cooled using just traditional fans. Conductive cooling through metal core PCBs are an ideal production option.

MCPCBs are most widely found in LED technologies, as they reduce the number of LEDs required to produce a specific PCB illumination. Light emitting diodes release a great amount of heat in applications such as:

Back light unit applications

Street safety applications (streetlights, lighting, etc.)

General lighting applications

System automotive LED applications

Power converters:? telecom, industrial, high voltage regulator, power supplies

Hybrid/electric motor control applications

Photovoltaic

Using a metal core PCB in these LED products and applications help to greatly reduce the heat emitted.

Other applications that are ideal for MCPCB integration are solar panels and motion control applications.
