Abstract: In examples, a method of manufacturing a transformer device comprises providing a first magnetic member and providing a laminate member containing primary and secondary transformer windings wound around an orifice extending through the laminate member. The method further comprises positioning a build up film abutting the laminate member. The method also comprises positioning at least a portion of a second magnetic member in the orifice. The method further comprises heat pressing at least one of the first and second magnetic members such that a distance between the first and second magnetic members decreases and such that the build-up film melts, thereby producing a transformer device.
