Abstract
A power supply module and its manufacturing method are disclosed. The manufacturing method for the power supply module includes: configuring a coil such that coil terminals are configured by way of electrical connection in the preset circuit connection configuration of the connector; preparing a mold cavity, and placing the connector housed with the coil and the electronic components into the mold cavity; making a magnetic mixture, and filling the mold cavity where the connector is placed with the magnetic mixture to form a magnetic body under pressure, wherein the magnetic body encapsulates at least the coil, the electronic components and a portion of the connector adapted to house the coil and the electronic components, and the terminal is exposed outside the magnetic body; demolding the magnetic body from the mold cavity; and increasing the temperature of the demolded magnetic body by heating. In this way, the molding pressure for forming the power supply module is lower and the manufactured power supply module has good performance of heat transfer.
