Pros and cons of PCB copper plating | 11 October, 2018

The so-called copper coating is to use the unused space on the flexible circuit board as the reference surface, and then fill it with solid copper, which is also called copper filling. The significance of copper clad is to reduce the ground line impedance, improve the anti-interference ability; reduce the voltage drop, improve the power supply efficiency; connect with the ground wire, and also reduce the loop area. Most PCB manufacturers also require PCB designers to make some changes for the purpose of making the PCB as undeformed as possible. For example ALLPCB, ALLPCB focuses on PCB prototype, they will require a copper or grid-like ground wire to be filled in the open area of the PCB.
