MCPCB, Metal Core PCB, thermal PCB

In recent years, LED industry has been rapidly developed, but the problem of heat dissipation has been puzzling the application and development of LED, especially high-power LED in the field of lighting. The application of metal substrate provides a new way to solve the heat dissipation of LED effectively.

Metal core pcb is abbreviated as MCPCB, it is made of thermal insulating layer, metal plate and metal copper foil, which has special magnetic conductivity, excellent heat dissipation, high mechanical strength and good processing performance. For metal core base material, there is aluminum and copper base materials. Aluminum substrate is a kind of metal-based copper clad plate with good heat transferring and dissipation function. Copper substrate has better performance than aluminum, but its price is relatively more expensive than aluminum.

Clients order aluminum pcbs more often, because the price of aluminum pcb is much more economic, they are used for LED lighting, audio frequency apparatus and communication electronic equipment.

Mcpcb Stack UP

A simple layer single sided MCPCB consists of a metal base (usually aluminum, or copper alloy), Dielectric (non-conducting) Layer, Copper Circuit Layer, IC components and solder mask.

Single Layer MCPCB Structure


COB MCPCB, known as "Chip-On-Board" Metal Core PCB, is a type of MCPCB used in thermoelectric separation application. 

Structure of COB MCPCB


Two (Double) layers MCPCB is consisting of two layers of copper conductor, put them on same side of metal core (usually aluminum, copper or iron alloy).

Structure of 2L MCPCB


It also has same two layers of copper conductor like Double layers MCPCB, but the metal core is in the middle of two conductor, so there're conductors (trace) on both sides of metal core, and were connected to each other by Vias. So we named it "Double sided MCPCB", and you can populated SMD on both top and bottom.

Multi Layers More Core PCB, you need to consult the salesperson first if PCBWay can be manufactured, The structure is similar with FR4 Multi Layers, but it much more complex to make.

According to the structure of metal core in the layers stack-up, pcbway offers single side MCPCB, two layers MCPCB. For two layers MCPCB, which divides into metal core in the middle of layers stack-up, metal core on the bottom side of layers stack-up.
