A power module fabrication method and structure thereof is disclosed. The method includes steps of: providing a metal plate and defining a pattern on the metal plate; cutting the metal plate according to the pattern to form a plurality of pins and the heat-conducting plate, wherein the pin is coupled to each other or to the metal plate via a connection part and the heat-conducting plate is coupled to the connection part via a fixing part; bending a first end of the pin to form an extension part and bending the fixing part to dispose the heat-conducting plate and the metal plate at different levels; providing a circuit board with a plurality of via holes and inserting the extension part into the via hole correspondingly and fixing the pin on the circuit board; forming a housing to encapsulate the circuit board therein, wherein the heat-conducting plate is inlaid on the housing and a second end of the pin is extended out of the housing; and cutting the connection part and the fixing part to separate the pin from each other and from the metal plate and isolate the pin and the heat-conducting plate. |
