After the circuit board is a double - coated copper or a single side of the copper cover good?
Reduce the pressure drop, improve the power supply efficiency, as well as connect with the earth wire to reduce the loop area.
The so-called copper cover, is on the PCB idle space as the reference surface, and then filled with solid copper, copper is also known as copper. The significance of copper coating is to reduce the ground resistance and improve the anti-jamming ability
Single sided circuit can only be designed simple. Complex single side can not wiring. Single sided only good installation of this benefit. So it's better to double cover copper.
