摘要： Embodiments of the present invention relate to nano-copper pillar interconnects. Nano-copper material is a mixture of nano-copper particles and one or more organic fluxes. In some embodiments, the one or more organic fluxes include organic solvents that help bind the nano-copper particles together and allow the nano-copper material to be printable. The nano-copper material is applied onto bond pads on a printed circuit board (PCB) via a printing process, a dipping process or the like, to form nano-copper covered PCB bond pads. A component can thereafter be coupled with the PCB at the nano-copper covered PCB bond pads. What is left when the solvents evaporate are nano-copper pillar interconnects that form, coupling the component with the PCB bond pads. The nano-copper pillar interconnects are of pure copper.

摘要： Embodiments of the present invention relate to a fixture design for pre-attachment package on package component assembly. The fixture design includes a plurality of pockets arranged in a N×M array. The plurality of pockets is sized to receive bottom packages. The fixture design includes global fiducials that are used to locate positions of the pockets on the fixture, and sets of local fiducials, with each set being specific to one of the pockets and used to refine the position of the location of a corresponding pocket. Each of the pockets can include one or more ear cuts for easy component placement and component removal. The fixture design can include a vacuum port for coupling with a vacuum source for drawing a vacuum to hold the bottom packages down. The fixture design can also include a cover that is used with the fixture to keep the components from being disturbed.

摘要： A strengthened semiconductor die substrate and package are disclosed. The substrate may include contact fingers formed with nonlinear edges. Providing a nonlinear contour to the contact finger edges reduces the mechanical stress exerted on the semiconductor die which would otherwise occur with straight edges to the contact fingers. The substrate may additionally or alternatively include plating traces extending at an angle from the contact fingers. Extending at an angle, at least the ends of the plating traces at the edge of the substrate are covered beneath a lid in which the semiconductor package is encased. Thus, when in use with a host device, contact between the ends of the plating traces beneath the lid and contact pins of the host device is avoided.
