Thick copper PCB board refers to a printed circuit board that uses thick copper foil as a conductive material. Compared with ordinary PCBs, thick copper PCBs have higher conductivity and mechanical strength, which can meet the requirements of high current, high voltage, and high mechanical stress.
1) Good thermal conductivity
Thick copper PCB circuit boards can effectively dissipate heat and prevent circuit board overheating. Compared to conventional circuit boards, thick copper PCB circuit boards have a thicker thickness and higher copper foil thickness, which can better conduct heat and ensure the stable operation of electronic devices.
2) Improving the reliability of electronic components
It can improve the reliability of electronic components. The thick copper layer of a thick copper PCB circuit board can provide better current carrying capacity, reducing the possibility of burning and heat concentration on the circuit board.
3) Enhance the mechanical strength of circuit boards
Due to the thickness of the copper layer, it has high mechanical strength. In some demanding environments, such as high vibration and high impact applications, the use of thick copper PCB circuit boards can improve the circuit board’s resistance to vibration and impact, avoiding damage to electronic components caused by mechanical stress.
4) Improve the transmission performance of electrical signals
The thicker copper layer can reduce the transmission loss and crosstalk of electrical signals. Especially for the design of high-frequency and microwave circuits, using thick copper PCB circuit boards can provide low impedance and low loss characteristics, improve the transmission efficiency and distance of electrical signals.
