MWB can realize the interleaving of circuit signals on the same layer, so the number of wires that can be routed in a single layer is significantly increased. Therefore, the manufacture of high-density wiring boards can be achieved in a smaller number of layers compared to traditional etching and plating boards. In addition, in MWB, insulated copper wires are used. The diameter of each line is the same as that of the same line. It can produce stable electrical characteristics such as accurate impedance control. The MWB line design is optimized by the program and the length is more suitable for circuit boards for high-speed signal switching. Compared with traditional etching circuit boards with limited manufacturing process, MWB is easier to complete manufacturing consistent with design values.
