Abstract:
A hybrid integrated circuit in a wafer level package for an implantable medical device includes one or more passive component windings formed, at least in part, along one or more routing layers of the package. The windings may be primary and secondary windings of a transformer, wherein all or part of a magnetic core thereof is embedded in a component layer of the wafer level package. If the core includes a part bonded to a surface of the package, that part of the core may be E-shaped with legs extending into the routing layers, and, in some cases, through the routing layers. Routing layers may be formed on both sides of the component layer to accommodate the transformer windings, in some instances.

Abstract:
The present disclosure provides methods and techniques associated with a planar transformer for an apparatus. The planar transformers include a substrate carrying electronic components and a continuous core that is formed by distributing the encapsulant material uniformly around the substrate unit to define a consistent cross-sectional area for the magnetic path. The electronic components include primary windings and secondary windings associated with the transformer. In some embodiments, the encapsulant material is molded to seals air gaps to the substrate unit.

The present disclosure provides methods and techniques associated with a planar transformer for an apparatus. The planar transformers include a substrate carrying electronic components, an upper core bonded on a first exterior surface of the substrate, and a lower core bonded on a second exterior surface opposed to the first side of the substrate. The electronic components include primary windings and secondary windings associated with the transformer. In some embodiments, the transformer includes encapsulant material that is dispensed over and between the components of the transformer to seal air gaps.
Abstract:
The present invention provides a packaging technique and apparatus that incorporates a flexible substrate package with a three-axis magnetic sensor for three-axis sensing in an implantable medical device. The apparatus includes three single-axis magnetic sensor integrated circuits (ICs) that are mounted to a substrate and encapsulated with a polymer mold compound. The substrate is excised around each of the sensor ICs to form panels that are folded to align the three single-axis sensors in the x, y and z axis.
