Metal core PCB Manufacturer
A metal core printed circuit board (MCPCB) is a type of printed circuit board (PCB) in which the substrate material is a metal core, typically aluminum or copper, rather than traditional FR-4 fiberglass or CEM-3 composite materials. Metal core PCBs are used in applications where the PCB must efficiently dissipate heat.
Committed to Manufacturing Solutions
A Metal Core Printed Circuit Board (MCPCB), also known as a thermal PCB or metal-backed PCB, is a type of PCB with a metal material as its base for the heat spreader portion of the board. The thick metal (almost always aluminum or copper) covers one side of the PCB. Many metal-core PCB manufacturers provide a variety of products and services for various applications. When choosing a metal core PCB manufacturer, consider the type of metal core material available, the thickness and thermal conductivity of the metal core, the size and capabilities of the manufacturer's production facilities, and the manufacturer's reputation and track record in the industry.

Testing Procedures
To find a metal core PCB manufacturer, you can start by searching online and looking for companies that specialize in the type of metal core PCBs you need. You can also ask for recommendations from industry professionals or other PCB users. It may also be helpful to visit trade shows and conferences, where you can meet and talk with different manufacturers and see their products in person.
There are several advantages to using metal core PCBs over traditional printed circuit boards:
- Heat dissipation: A metal core PCB acts as a heatsink, allowing it to dissipate heat more effectively than a traditional PCB. This is especially useful in applications where the PCB must dissipate a significant amount of heat, such as power electronics and LED lighting.
- Thermal stability: The metal core has a more stable and consistent thermal expansion coefficient, which can help prevent warping or cracking due to temperature changes.
- Improved performance: Metal core PCBs’ improved heat dissipation and thermal stability can lead to improved performance and reliability in high-power and high-temperature applications.
- Reduced component stress: The metal core can help distribute heat evenly across the PCB, reducing stress and extending component life.
- Metal core PCBs can be customized with various metal core materials, thicknesses, and shapes to meet the specific needs of various applications.
- Cost-effectiveness: While metal core PCBs are more expensive up front, their improved performance and lifespan can make them more cost-effective in the long run, especially in applications where traditional PCBs would fail due to heat or other environmental conditions.
