A circuit board includes a first multilayered structure, a second multilayered structure, a third multilayered structure, a first adhesive layer, a second adhesive layer and a plurality of hollow portions. The first adhesive layer is disposed between the first multilayered structure and the second multilayered structure. The second adhesive layer is disposed between the second multilayered structure and the third multilayered structure, wherein the second multilayered structure is arranged between the first adhesive layer and the second adhesive layer. The plurality of hollow portions are formed on at least one of the first multilayered structure, the second multilayered structure and the third multilayered structure. When the circuit board is bent, a force is applied on the plurality of hollow portions to make the plurality of hollow portions deform and change a cross-sectional area of each of the plurality of hollow portions.

Circuit board and manufacturing method thereof

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.
