A circuit board with conductive wiring which is precisely shaped and sized includes a two-part conductive element, namely a first conductive wiring layer and a second conductive wiring layer, a first cover film and a second cover film. The first conductive wiring layer and the second conductive wiring layer are in direct contact to each other. A projection of the first conductive wiring layer and a projection of the second conductive wiring layer along a direction perpendicular to the circuit board overlap with each other. The first and the second cover films wrap the first and the second conductive wiring layers, respectively.

Circuit board

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.

Printed circuit board with high-capacity copper circuit

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