1. Metal PCB board, also known as thermal PCB or metal back PCB, is a type of PCB based on metal materials, used for the heat dissipation part of the board.
2. The metal core of the PCB helps to dissipate heat more efficiently than traditional FR4 boards, making it ideal for high-power LED lighting, automotive, and power supply applications.
3. The metal PCB allows for better thermal conductivity, reducing the operating temperature and improving the overall performance and reliability of the electronic device.
4. In addition, the metal PCB can be more compact and lightweight compared to traditional PCBs, making it a popular choice for applications where space and weight are critical factors.
5. Furthermore, the metal PCB can also provide electromagnetic shielding, making it suitable for applications in which electromagnetic interference needs to be minimized.
6. Overall, the metal PCB offers a range of benefits for various applications, including improved thermal management, reduced size and weight, and enhanced electrical performance.
Metal PCB boards are a subset of the PCB family, based on metal in the heat dissipation area. The insulation layer (also known as the IMS layer), copper foil, and metal plate are the three components that make up multi-layer printed circuit boards. They have high mechanical strength, excellent processing performance, good heat dissipation, good magnetic conductivity, and high tensile modulus.
Various methods including the use of conductive and non-conductive materials were used to achieve this result. Most metal PCB boards include aluminum or copper as their substrate, or a combination of aluminum and copper or other metal alloys.
The advantages of metal PCB boards:
1. Compared with standard circuit board materials, the thermal expansion and dimensional stability of metal PCB materials are greatly improved. Metal core PCB layout can improve power density, electromagnetic shielding, and capacitance coupling.
2. Hot through holes are often added to metal PCB prototypes to improve their thermal performance. When high-power LED lighting is required for small enclosures, engineers usually choose copper metal PCB LEDs because copper has better thermal performance than aluminum.
3. Insulated metal substrate technology performs excellently when a large amount of heat must be removed. Due to the many advantages of metal PCB boards over FR4 PCBs, they are widely used by engineers and designers.
4. They can integrate dielectric polymer layers with high thermal conductivity to reduce thermal resistance. They transfer heat 8 to 9 times faster than FR4 PCB, dissipating heat and reducing the temperature of heating components, thus improving their performance and lifespan.
Comparison with FR4 PCB:
1) Thermal conductivity: FR4 has low thermal conductivity of around 0.3W, while metal circuit boards have higher thermal conductivity ranging from 1.0W to 4.0W, with an average of approximately 2.0W.
2) Plated through holes: Typically, FR4 PCBs use plated through holes, while in MCPCB, a 1-layer PCB cannot have plated through holes as all components are usually surface-mounted.
3) Heat release: FR4 PCBs use via holes for heat transfer, while metal PCB materials have their heat dissipation function, eliminating processes such as drilling, electroplating, and deposition.
4) Solder mask: The solder mask of FR4 PCB is usually dark in color and applied at the bottom and top, while for metal PCBs, the solder mask is usually white and only applied to the top.
5) Thickness: FR4 PCBs have different thicknesses and can use different layers and material combinations, while the thickness variation of metal PCB boards is limited by the thickness of the dielectric and the available thickness of the substrate.
The substrate of metal PCB is metal, used for the heat dissipation area of the board, using unique substrate materials specifically designed to help improve the reliability of the design. Metal PCBs are widely used in circuit boards, involving cooling issues and the use of a large number of LEDs.
