Metal Core PCBs also called MCPCBs, whose substrate layer is a metal base. As Metal Core PCB means the base material for PCB is metal and not normal FR4/CEM1-3 etc. Commonly used metals are aluminum and copper alloy. The most common metals of MCPCBs used are aluminum, copper, and steel alloy. Aluminum-based PCBs are the most cost-effective; they exist good heat conductivity and thermal dissipation ability at low prices. Copper-based PCBs perform better than aluminum-based ones.
Metal core PCBs are not very common in consumer products, but they abound in the industry, aerospace, lighting systems, power electronics and other fields that require high reliability. So in this article, we will give you some information about the metal core PCB. In this way, you will find out whether you need the metal core PCB.
Here is the content list:
1. The materials used by the metal core PCB.
2. The applications of the metal core PCB.
3. The advantages of the metal core PCB.
The basic material used in PCB is metal, not FR4 or CEM3 material. The most commonly used metals are aluminum, steel alloys and copper. Aluminum is cheap and has a good capability of heat dissipation and transmission. Copper does better in heat dissipation and transmission than aluminum and stainless steel, but it is expensive. Stainless steel is harder than copper and aluminum, and its thermal conductivity is also very low. Therefore, the choice of metal in this kind of PCB will finally depend on the application in which they are used.
In fact , the applications that employ the metal core PCB are widely spread in our life. For example, we can find the metal core PCB in street safety applications (streetlights, lighting, etc. ) , system automotive LED light and power converters like telecommunications, industrial, high voltage regulator, power supplies. Also, engineers always put the metal core PCBs in hybrid/electric motor control applications and some audio devices.
The major advantage of MCPCB over conventional PCB lies in its ability to efficiently dissipate heat away from the components. This is because that the metal PCB made of aluminum has excellent thermal conductivity and helps keep the internal components safe. When the aluminum PCB is heated to a temperature of 30 degrees Celsius to 140~150 degrees Celsius, the metal core PCB shows good dimensional stability
The manufacturing process and design rules of the metal core PCBs are similar to conventional PCBs. We provide metal core PCB prototype fabrication and MCPCB fabrication quantities for both aluminum core and heavy copper PCBs. Thermal management PCBs or MCPCBs are processed with standard SMT assembly equipment in the PCB manufacturing process.
