Apparatus and methods for secure attachment of a heat sink to its respective retention clip as well as attachment to an electronic device are presented. One embodiment of a retention clip retention apparatus consists of a protruding hip depending from a side of a heat sink protrusion adapted to capture the retention clip between the hip and the heat sink body. One embodiment of a method for forming the hip consists of using a tool to deform the heat sink protrusion. One embodiment of heat sink lateral retention apparatus consists of one or more split bobbins adapted to attach to the retention clip to prevent lateral motion of the heat sink with respect to the clip.

Heat sink and retaining clip assembly

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.

Anti-tombstoning structures and methods of manufacture

A heatsink which includes a body having a first arm and a second arm and having a mounting area between the first arm and the second arm. The mounting area is dimensioned to hold a heat generating electronic component. The mounting area is dimensioned so that when the component is located within the mounting area, the first arm and the second arm apply opposing forces against the component so that the component is held within the mounting area by the first arm and the second arm.
