An apparatus includes a laminate, the laminate including a dielectric layer having a first surface and a second surface opposed to the first surface, and a conductive layer forming a circuit element overlying the first surface of the dielectric layer. The apparatus further includes a magnetic layer over the conductive layer. A first edge surface of the magnetic layer is coplanar with a first edge surface of the laminate, and a second edge surface of the magnetic layer is coplanar with a second edge surface of the laminate.

Packaged isolation barrier with integrated magnetics

A method includes performing a printing process that deposits a magnetic paste onto a first side and into an opening of a laminate; curing the magnetic paste to form a first transformer core piece having a first portion along the first side and a second portion filling the opening of the laminate; joining a second transformer core piece to a side of the second portion of the first transformer core piece to form a transformer. A transformer includes a laminate; a first core piece; and a second core piece, the first core piece comprising: a cured magnetic paste, a first portion along a side of the laminate, and a second portion filling an opening of the laminate, the second core piece extending along a side of the second portion of the first transformer core piece, and the laminate having windings that encircle the opening.

Method for manufacturing an integrated transformer with printed core piece

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.
