Advantages of PCB Copper Substrate

Hits : 3

PCB copper substrate is a copper foil as a conductive layer of the substrate.

The conductive layer is a part of a semiconductor device with good electrical conductivity and is usually composed of semiconductor material doped with specific impurities. The conductive layer is responsible for charge transfer in semiconductor devices, such as the source and drain in field effect transistors, or the emitter and collector in bipolar transistors. The main role of the conductive layer is to transmit current and signals, and its performance has a significant impact on the performance and reliability of semiconductor devices. In circuit boards, the conductive layer is usually made of copper because copper has good conductivity and stability. The conductive layer plays the role of signal transmission and current conduction in the circuit board, and can provide mechanical support and fixation of the circuit board to improve the stability and reliability of the circuit board. In addition to its application in semiconductor devices and circuit boards, the conductive layer can also be used in other fields, such as electromagnetic shielding, electric heating film and so on.


The advantages of PCB copper substrate are as follows:

High Conductivity: Copper substrate has high conductivity, which can provide good electrical performance and make the current transmission between electronic components smoother.

High Mechanical Strength: Copper substrate has high mechanical strength, which can ensure the flatness and durability of the PCB board, thus extending the service life of the PCB board.

Good Thermal Stability: Copper substrate has good thermal stability, can withstand higher temperatures and heat, so that the PCB board in the process of long-term use to maintain stability.

Excellent Processing Performance: Copper substrate processing performance is excellent, to meet a variety of complex PCB design and manufacturing requirements, and easy to drill, cut, bend and other processing operations.

Anti-corrosion: Copper substrate has good anti-corrosion properties, can resist the erosion of various chemicals, thus ensuring the long-term stability and reliability of the PCB board.

Environmental Protection: The production and use of copper substrates will not produce harmful substances in the process, harmless to the environment, in line with environmental requirements.

PCB copper substrate has the advantages of high electrical conductivity, high mechanical strength, good thermal stability, excellent processing performance, anti-corrosion, environmental protection, and so on, so it has been widely used in the electronics industry.
