Abstract
A printed circuit board with high-capacity and high-current copper circuit includes a conductive trace, a first protecting layer, and a second protecting layer on opposite sides of the conductive trace. The conductive trace includes a basic conductive trace pattern, a first conductive trace pattern, and a second conductive trace pattern. The first and second conductive trace patterns are directly formed on opposite surfaces of the basic copper conductive trace pattern. A width of trace of the first conductive trace pattern is the same as a line width of the second conductive trace pattern.
