Description

technical field [0001] The invention relates to the technical field of circuit board manufacturing, in particular to a circuit board for an energy-saving fan and the energy-saving fan. Background technique [0002] At present, before the appearance of the PCB board, the interconnection between electronic components is to rely on the direct connection of wires to form a complete circuit. With the continuous development of science and technology, the PCB board has become an important position in the electronics industry. In recent years, my country's PCB board manufacturing industry has developed rapidly, but there are also certain problems in the existing PCB boards. The circuit layers in the existing PCB boards only have a single-layer transmission line layer, and the loss is too large during use and cannot be shielded. Therefore, it is particularly important to find a circuit board for an energy-saving fan that can meet the low-loss requirements of high-frequency transmission...
