In addition to offering vastly superior heat dissipation over the material for standard circuit boards, metal core PCB material also offer superior thermal expansion, along withsignificantly better dimensional stability.

With metal core PCB design, you can have higher power density, better electromagnetic shielding, and improved capacitive coupling. Although designers do not need to usethermal vias for metal core PCB prototypes, designers sometimes use them to improve on the thermal performance.

As copper has better thermal characteristics than aluminum does, engineers prefer copper metal core PCB LEDs where they have to house high wattage LEDs in smallenclosures. Metal core Printed circuit boards manufacturers selectively remove dielectric material to expose the base metal for attaching the LED chip. The direct thermal pathimproves performance by reducing the thermal resistance even more.

Technical Parameters:

Metal core Printed circuit boards manufacturers use MCPCB for thermoelectric separation applications. They place the microchip or die in direct contact with the metal core,which helps in heat dissipation. They electrically interconnect the traces of the circuit board with wire bonding. This allows them to achieve thermal conductivity of over 200W/mk for the COB MCPCB.

Metal core PCBs greatly reduce board space while replacing other components such as heat sinks. Mounting of other components such as power transistors becomes easier,as the presence of the metal substrate allows elimination of grease, mica, and rubber insulators under the power devices by mounting them directly on the metal substrate.Elimination of the insulating hardware improves heat transfer.

Designers can eliminate whole sections of printed wiring boards', thereby eliminating interconnects, by using etched traces on the metal core PCBs. They can also replace many discrete devices at the board level by using power and passive devices of the surface mount type.

Applications of Metal Core PCBs

Apart from use in LED lights, you can find metal core PCBs being used in several other applications. For instance, the size constraints and watt-density requirements of DC-DCconverters force engineers use metal core PCBs, as they are available in a variety of thermal performances, are compatible with mechanical fasteners, and are highly reliable. Itis possible to use the metal core PCBs in various form factors and manufacturers can fabricate substrate metals in a wide variety, and with different thicknesses and copper foilweights.

Automotive, audio, motor control and power conversion applications are increasingly using metal core PCBs, as they offer several advantages that include superior attachmentcapabilities, surface mount assembly, and excellent thermal performance. Fabricators often selectively remove the dielectric and form the metal core with 3-D features makingthe metal core a versatile substrate.

The material construction of the metal core PCBs allows mounting configurations suitable for solid-state relays in several control applications, which is not possible withceramic substrates. Metal core PCBs offer thermally efficient and mechanically robust construction that a solid-state relay construction demands. Manufacturers arediscovering new types of metal core PCB material, especially dielectrics, to meet the high thermal performance expectations that can even out-perform existing ceramic-based designs.
