The MCPCB (Metal Core PCB) is a PCB made of metalcore and copper to laminate, which has good heat dissipation.
In general, the MCPCB board comprises three layers: the copper foil, the insulating layer, and the metal-clad layer.
Metal core PCBs can minimize thermal resistance. This means they have excellent thermal conductivity compared with FR4.
Single-sided MCPCB board is the most common type. It has a simple process. It is used a lot in LED lighting. This is in contrast to other metal core PCB boards. It consists of three parts: the copper foil, the insulating layer, and the metal-clad layer.
2 Layer MCPCB board can layout components on both sides. The structure is complex. It has five parts: the circuit layer, the dielectric layer, the aluminum-clad layer, the dielectric layer, and the circuit layer. MCPCB fabrication involves more resin filling and plating processes. These require twice as many drillings.
The high-performance power supply industry uses multilayer MCPCB boards. They are made of thermally conductive dielectrics. These structures have one or more layers of circuitry buried in a dielectric, with blind vias used as thermal vias or signal paths.
Its core material is aluminum metal. Aluminum Core PCB usually has three layers. These are aluminum substrate, dielectric layer, and copper foil layer. It has good heat dissipation performance and is suitable for high-power applications such as LED lighting.
One of the latest developments in metal core PCB is flexible dielectrics. These materials provide excellent electrical insulation, flexibility, and thermal conductivity. When applied to a flexible MCPCB board, the product can be realized in various shapes and angles and can be bent without cracking. Cost savings on expensive fixtures, cables, and connectors.
Copper Core PCB is copper metal core PCB. The copper core PCB dissipates heat well. It is good for high-frequency circuits. It is also good for cooling precise communication equipment and buildings.
Iron Core PCB metal clad layer is iron. Iron is much harder than aluminum. This is true despite the manufacturing process and difficulty of the aluminum. It’s used in high-end motors, high-end product equipment, and motors.
The MCPCB(Metal Core PCB) can cut thermal resistance. It has a smaller thermal resistance. Also, its thermal expansion coefficient is closer to that of copper foil.
It has excellent thermal conductivity and heat dissipation performance. This lowers the module's temperature and makes it last longer.
The MCPCB board can carry a higher current with the same thickness and line width.
MCPCB board can replace ceramic substrate, better mechanical durability. At the same time, strong and tough materials can make large-area printed boards. They can also place components.
To ensure electronic circuits work well, some components in products must block radiation and electromagnetic interference. The MCPCB(Metal Core PCB) can act as a shielding plate to shield electromagnetic waves.
L'aluminium du panneau MCPCB utilisé comme matière première est non toxique et recyclable. Se conformer aux exigences RoHs.
Aluminum of metal core PCB is amazingly lightweight. It has great strength and flexibility, which is very convenient.

NC drilling is the first step of MCPCB(Metal Core PCB) manufacturing. The drills are CNC-controlled, following the Gerber drilling file.
Solder mask coating will protect the copper and trace from mechanical and environmental damage. After applying the solder mask, the panel gets added to with the legends. This is done through screen printing of identification ink in different colors.
The MCPCB board has been cycling in the final milling process, and the CNC machine follows the MCPCB outline gerber to mill and V-CUT.
All the good MCPCB boards will be small vacuum packaging and carton packaging. Then, it is shipped worldwide through UPS, DHL, and Fedex Express.
