Multilayer metal core PCB (MCPCB) is a type of printed circuit board that consists of multiple layers of conductive traces and insulating materials bonded together with a thermally conductive metal core. The metal core layer provides superior heat dissipation and mechanical stability compared to traditional PCBs, making it an ideal choice for applications that require high power and high thermal dissipation.
The metal core layer in MCPCBs is typically made of materials with high thermal conductivity, such as aluminum or copper, which allow heat to be dissipated quickly and efficiently from the active components on the PCB. The active layers of the PCB, which contain the conductive traces, are bonded to both sides of the metal core layer using a special bonding process. The insulation layers are then sandwiched between the active layers to create the multilayer structure.
MCPCBs are widely used in various industries such as LED lighting, automotive electronics, and power electronics. LED lighting applications, in particular, have been a driving force behind the increased demand for MCPCBs, as they require efficient heat dissipation to prevent damage to the LEDs and maintain optimal performance. Other applications of MCPCBs include power supplies, motor controllers, and audio amplifiers.
The unique combination of thermal conductivity, mechanical stability, and electrical performance offered by MCPCBs makes them a popular choice for applications that require high power and high thermal dissipation.
A multilayer metal core PCB is composed of several layers of materials, each with a specific function in the operation of the PCB. The composition of MCPCB typically includes the following layers:
In addition to the layers mentioned earlier, multilayer metal core PCBs also typically contain holes that connect the various layers of the PCB. These holes are called vias.
Vias are used to create electrical connections between the different layers of the PCB. They are typically drilled through the entire PCB, from the top conductive layer to the bottom conductive layer, and then plated with metal to ensure a solid electrical connection. Vias can be classified into two types: through-hole vias and blind vias.
Through-hole vias are drilled through the entire thickness of the PCB, from the top to the bottom layer, and are used to create electrical connections between all layers of the PCB. They are typically larger in diameter than blind vias and can be filled with conductive material to further enhance the electrical connection.
Blind vias, on the other hand, are drilled partially through the PCB, connecting only some of the layers. They are typically smaller in diameter than through-hole vias and are used when space is limited on the PCB. Blind vias can be drilled from the top or bottom layer and can also be filled with conductive material.
The placement and size of vias are important design considerations for MCPCB. Vias should be placed strategically to avoid interference with other components and to optimize the electrical performance of the PCB. The size of the vias should be carefully chosen to ensure proper plating and electrical connectivity.
