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 transceiver assembly includes a cage and a heatsink. The cage includes first and second spaced apart walls and a third wall that spans the first and second walls. The third wall defines an opening, and the third wall includes two spring arms that each extend into the opening. The heatsink includes a heatsink body including a first surface and a protrusion that extends from the first surface of the heatsink body and a pair of spring-arm receivers positioned on the first surface of the heatsink body. Each of the pair of spring-arm engagement portions is configured to engage with a corresponding one of the two spring arms of the cage when the heatsink is attached to the cage.

Abstract: A connector includes a thermal metamaterial. The thermal metamaterial provides heat flow paths from inside of the connector to outside of the connector. In addition, an electrical connector includes an electrically insulating housing, an electrically conductive contact included in the electrically insulating housing, and a metamaterial thermally connected to one of the electrically insulating housing or the electrically conductive contact. The metamaterial thermally cools the electrical connector.
