Abstract: A substrate reinforcement or stiffener can be toolless, slide-on, slide-off, and removable. A hold down can carry pre-attached solder balls, solder units, or fusible elements. Fusible elements can be shaped to reduce thermal and mechanical stresses when reflowed onto a substrate. A heat-producing article can include a heat-dissipation material selectively located on, or immediately adjacent to, a heat-producing article. Clips with a plurality of fingers can be added to power conductors. Graphene strips, graphene coatings, or nanomaterials can be applied to electrically non-conductive articles and are able to selectively direct unwanted heat away from the heat-producing article. Electro-magnetic interference can be reduced by selective placement of voids in a shield of an electrical component.

Abstract: A surface mount device inductor has a package casing sized to attenuate electromagnetic coupling between the inductor coils of the surface mount device inductors. The surface mount device inductor includes an inductor coil, an anode structure disposed over a first end of the inductor coil and a cathode structure disposed over a second end of the inductor coil opposite the first end, the cathode structure being spaced apart from the anode structure. One or both of the anode structure and the cathode structure comprise a shield portion disposed at least partially over the inductor coil to thereby reduce electromagnetic coupling between adjacent surface mount device inductors. The package casing makes the surface mount device inductors self-shielding. The surface mount device inductors can be incorporated into a radiofrequency module, and can be incorporated into a front end system of a wireless mobile device.
