The invention provides a four-in-one network transmission pulse wafer, especially a magnetic core is wound with a coil group through an automatic winding process, and the two sides of each coil group are welded on the two sides of the multiple wire ends and are respectively welded on the two sides. The welding parts on each pad can reduce man-hours, improve product yield, and then reduce manufacturing costs.

According to the continuous advancement of the age of science and technology, many electronic and electrical products have become indispensable important tools and tools in life and work. In various electronic and electrical products, the internal electrical and circuit equipment are roughly related. Through the combination of passive components and active components to form an electronic control circuit with specific functions, as for so-called passive components such as transformers or inductors, resistors or capacitors of magnetic components, and pulse transformers, inductors, etc. of the magnetic components have current Induction immediately generates an induced magnetic field to achieve the effect of energy storage and energy release.

The traditional pulse transformer uses two sets of coils wound on a toroidal core. The two ends of the two sets of coils each extend to the side walls of the two sides of the core to provide various types of external The contacts on the electronic device circuit board form an electrical connection. When the current passes through the coil, the magnetic field effect can be generated by the magnetic core, which can provide the electronic device circuit with the effect of changing the voltage and current.
