Copper coating is very important in PCB production process, and sometimes the success or failure of copper coating is related to the quality of the whole plate.The so-called copper coating is the empty space that fills the solid copper into the PCB substrate. . There are two methods of copper covering copper and mesh overlaying copper, which increases the current and shielding in large area. However, if the wave crest is soldered, the board may be tilted up and even blister.The copper coating can reduce the heating surface of copper and also play a role of electromagnetic shielding.But the grid is made up of walking lines, and if the width of the line is not appropriate, there will be interference signals. Copper clad for PCB has many advantages, such as raising the ability to resist noise, to reduce the potential difference value, reduce the ground impedance, improve the anti-interference ability, lower pressure drop, improve the efficiency of power supply, connected to the ground, reduce the loop area, cooling, reducing the impedance.
