Abstract
In one aspect, an electric coil structure is disclosed. The electric coil structure includes a magnetic core and a substrate. The substrate comprises a conductive material that is embedded in an insulating material. The substrate has a first portion and a second portion and the first portion of the substrate is wrapped around the core. The substrate can have a first portion having a plurality of contacts and a second portion having a corresponding plurality of edge contacts. The coil structure includes an alignment structure. The alignment structure can facilitate attachment of the first portion to the second portion to define a coil about the magnetic core. The alignment structure can comprise a redistribution substrate. The redistribution substrate can be disposed between the first portion and the second portion with the conductive material of the first portion electrically connected to the conductive material of the second portion through the redistribution substrate to define at least one winding. The alignment structure can include an adhesive. The adhesive can be disposed in the recess electrically connecting the first and second portions to define at least one winding. The coil structure can include a solder joint. The solder joint can be disposed between the plurality of contacts and the corresponding plurality of edge contacts making electrical connections between the first and second portions to define at least one winding such that the solder joint is exposed on the first portion.
