Problems solved by technology
In the traditional micropower power supply structure, the transformer on the circuit board assembly is a magnetic ring transformer, and there are generally 6 or 9 pin terminals on the transformer. In order to realize the electrical function, the pins of the magnetic ring transformer need to be connected with the The pads are soldered. Because the pins are very thin, these pins need to be manually soldered with a soldering iron, and the pins of the circuit board also need to be soldered separately. The welding time is long, and the soldered pins are easy to fall off
Therefore, in order to solve the above-mentioned problems of magnetic toroidal transformer pin falling off and welding time-consuming, there is an urgent need for a method for manufacturing a direct plug-in micropower module power supply
