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.

Abstract: An apparatus includes a magnetic core and an inductor. The magnetic core has a cylindrical boss and a base plate. The cylindrical boss has a first end and a second end. The base plate extends perpendicularly from the first end of the cylindrical boss. The base plate has a top side and a bottom side. The inductor includes a coil, a first terminal, and a second terminal. The coil is disposed on the top side of the base plate about the cylindrical boss. The first terminal is wrapped from the top side of the base plate to the bottom side of the base plate. The second terminal is wrapped from the top side of the base plate to the bottom side of the base plate.

Abstract: In some examples, an electronic device comprises a first magnetic member, a first adhesive layer abutting the first magnetic member, a second magnetic member, a second adhesive layer abutting the second magnetic member, and a laminate member between the first and second adhesive layers. The laminate member comprises first and second transformer coils, an electromagnetic interference (EMI) shield coil, and a set of thermally conductive members coupled to the EMI shield coil and extending in three dimensions. At least some of the thermally conductive members extend vertically through a thickness of the laminate member so as to be exposed to top and bottom surfaces of the laminate member. The electronic device includes a thermally conductive component coupled to at least one thermally conductive member in the set of thermally conductive members.

Abstract: In examples, a transformer device comprises a first magnetic member; a second magnetic member; and a substrate layer between the first and second magnetic members. The substrate layer comprises a transformer coil. The transformer device includes a third magnetic member inside the substrate layer. The transformer coil encircles the third magnetic member. The third magnetic member physically separates from the first and second magnetic members.

Abstract: A method for backside metallization includes inkjet printing a pattern of nanosilver conductive ink on a first surface of a silicon wafer. The silicon wafer includes a plurality of dies. The pattern includes a clearance area along a scribe line between the dies. A laser is focused, through a second surface of the wafer, at a point between the first surface of the silicon wafer and the second surface of the silicon wafer. The second surface is opposite the first surface. The dies are separated along the scribe line.
