Wat is MCPCB?

The MCPCB (Metal Core PCB) is a PCB by metal core and copper to laminate which has good heat dissipation. In general, MCPCB board is composed of three layers which are the copper foil, the insulating layer and the metal-clad layer. Compared with FR4, the metal core PCB can minimize thermal resistance, which makes it has excellent thermal conductivity.

Single Sided MCPCB Board

Single sided MCPCB board is the most common type. Compared with other types of metal core PCB board, its process is simple and its application is particularly extensive, often used in LED lighting products. It consists of three parts: the copper foil, the insulating layer and the metal-clad layer.

2-laags MCPCB-bord

2 Layer MCPCB board can layout components on both sides. The structure is relatively complex and consists of five structures: The circuit layer, the dielectric layer, the aluminum-clad layer, the dielectric layer, and the circuit layer. There are more resin filling processes and plating processes in MCPCB fabrication, which require twice drillings.

Meerlaagse MCPCB-plaat

In the high-performance power supply industry, multilayer MCPCB board are made of multilayer 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.

Flexibel MCPCB-bord

One of the latest developments in metal core PCB is the flexible dielectric. These materials provide excellent electrical insulation, flexibility and thermal conductivity. When applied to 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 heat dissipation of the copper core PCB is very good, and it is suitable for high-frequency circuits, as well as heat dissipation of precision communication equipment and architectural industries.

PCB met ijzeren kern

Iron Core PCB metal clad layer is iron. The hardness of the iron substrate is much greater than the manufacturing process and difficulty of the aluminum substrate, It’s used in high-end motors, high-end product equipment and motors.

Kenmerk van MCPCB-printplaat

Good heat dissipation

The MCPCB(Metal Core PCB) can minimize the thermal resistance, has smaller thermal resistance, and the thermal expansion coefficient is closer to that of copper foil. Make the MCPCB board have excellent thermal conductivity and heat dissipation performance, reduce the operating temperature of the module and prolong the service life.

High current carrying

With the same thickness and the same line width, the MCPCB board can carry higher current

Good machinability

MCPCB board can replace ceramic substrate, better mechanical durability. At the same time, high strength and toughness can realize large-area printed board manufacturing and component placement.

Good electromagnetic wave shielding

In order to ensure the performance of electronic circuits, some components in electronic products need to prevent radiation and interference of electromagnetic waves. The MCPCB(Metal Core PCB) can act as a shielding plate to shield electromagnetic waves.

Environmental friendly

Het aluminium van MCPCB-plaatmateriaal dat als grondstof wordt gebruikt, is niet giftig en recyclebaar. Voldoe aan de RoHs-vereisten.

Light weight

Aluminum of metal core PCB has amazing light weight with excellent strength and elasticity, which is very convenient.
