The invention provides thermally conductive material so that less heat traveling from one side of a layer will reach connection material on another side of a layer. Rather, some of the heat will be conducted away by the thermally conductive material and dissipated.

Via heat sink material

A socket may receive both ball grid and land grid array packages. Thus, in some embodiments, the early package prototypes, without solder balls, may be packaged in the same socket design that is ultimately used for production devices using ball grid array packaging. Both land grid array and ball grid arrays may be self-centered on the socket in some embodiments. An S-shaped spring contact may be utilized to electrically connect to either solder balls or lands in a wiping action.

Making electrical connections between a circuit board and an integrated circuit

An integrated circuit (IC) package socket is provided with an array of single-piece socket contact pins arranged to connect an IC package to a circuit board. The single-piece contact pin is supported at a middle portion of the contact pin and includes two acutely angled bends that allow the two ends of the contact pin to independently resiliently engage the package lands of the IC package and the contact pads of the circuit board. The contact pins are further shaped and arranged to laterally swipe the package lands and contact pads during engagement to scrape away or penetrate through any oxide or other contaminant buildup.

Integrated circuit package socket and socket contact

A device includes a substrate. The substrate further includes a first major surface including a plurality of lands, and a second major surface. At least one component is attached to at least some of the plurality of pads on the first major surface. At least one sacrificial component is attached to the first major surface. The at least one component has a first height with respect to the first major surface, and the at least one sacrificial component has a second height with respect to the first major surface. The second height is greater than the first height. The sacrificial component includes a fuse.

Sacrificial component

A substrate, such as a printed circuit board (PCB), has pairs of pads to which terminals of electronic components, such as capacitors, can be mounted. The pads have perimeters, for example, in the shape of rectangles, circles, or ovals. In one embodiment, to reduce asymmetrical, lateral, surface-tension forces that can cause the components to tombstone due to uneven heating of solder fillets on the pads during solder reflow, the edge of the perimeter of each pad opposite the inter-pad region contains one or more notches or indentations. Also described are an electronic assembly, an electronic system, and various methods of fabrication.
