What is Copper Base PCB?

Copper core circuit boards are a type of metal core PCB. With their layered design using a copper base, these PCBs offer superior thermal conductivity. Base layer: The base layer is made of a copper substrate that offers high thermal conductivity and heat transfer.

With the rapid development of electronic equipment, it is required that electronic equipment can maintain stable performance and temperature when working at high frequency and high power. Therefore, heat dissipation technology has become a major concern. Among them, the copper-based PCB heat dissipation technology has developed rapidly, and has become a hot topic in the industry.

1. The importance of the heat dissipation of the copper circuit board

In the process of electronic manufacturing, due to the power concentration and high frequency factors, when the energy consumption is too much, the temperature of electronic components will rise sharply, thus affecting the normal use of the equipment. Copper PCB heat dissipation technology using a certain process to produce copper PCB board, its thermal conductivity is good, can effectively enhance the heat transfer effect of heating components and air, reduce the temperature, and ensure the stability and reliability of the equipment.

2.Copper base PCB process flow

• Copper PCB is mainly realized through the following process steps:
• Prepare the Laminates: select high purity copper board as the  Laminates;
• Chemical cleaning: clean the PCB with chemical solution, and obtain a clean surface;
• Electroplating: soak the copper surface in a certain electrolyte for electrolysis to form conductive copper film layer;
• Thermal bonding: press it with high thermal conductivity material as a whole. The above steps can produce a high quality copper PCB, with the advantages of high thermal conductivity and good compatibility.

3. Advantages of a copper-based PCB

Copper-based PCB is widely used in the process of electronic equipment manufacturing, mainly has the following advantages:

• Excellent heat dissipation performance: copper board high heat conductivity, more than 2 times of other similar materials;
• High strength and rigidity: copper-based PCB will not reduce strength due to physical and chemical corrosion, and not easy to deformation;
• Good processing performance: copper-baed PCB can be processed through a variety of cutting, stamping and drilling, and the production of various complex shapes of heat sink.

4. Future trend

With the continuous development of technology, copper-based circuit boards heat dissipation technology will also usher in more improvements and development. Among them, the future trend mainly includes the following directions:

• The processing technology of copper PCB will be more complicated and diversified;
• The combination of copper PCB and other materials with higher thermal conductivity to improve the thermal conductivity;
• The thinning trend of copper PCB will continue to meet the demand of lightweight;
• The heat dissipation performance of copper PCB will be further improved by nanotechnology and other means.

Whether in the development and use of electronic equipment process, copper PCB heat dissipation technology plays a vital role. With its excellent heat dissipation performance and diversified processing technology, it provides an important guarantee for the maintenance, maintenance and long-term use of the equipment.
