  • Patent number: 10699972
    Abstract: A symmetrical, flat laminate structure used to minimize variables in a test structure to experimentally gauge white bump sensitivity to CTE mismatch is disclosed. The test structure includes a flat laminate structure. The method of using the test structure includes isolating a cause of a multivariable chip join problem that is adversely impacted by warpage and quantifying a contribution of the warpage, itself, in a formation of the multivariable chip join problem.

  • Patent number: 10342160
    Abstract: Structures and methods for providing heat sink attachments on existing heat sinks. According to a device, a first heat sink comprises a first base and fins extending from the first base. The first base comprises a cutout therein and a first base bottom surface contacting a first electronic component. A second heat sink comprises a second base and fins extending from the second base. The second heat sink is located in the cutout of the first heat sink. The second base comprises a second base bottom surface contacting a second electronic component. A pressure plate is attached to the first heat sink and overlays the second heat sink. The pressure plate contacts the second heat sink and applies pressure between the second heat sink and the second electronic component.

  • Patent number: 10014273
    Abstract: A fixture assembly and method of forming a chip assembly is provided. The fixture assembly includes a first plate having an opening sized to accommodate a chip mounted on a laminate. The fixture assembly further includes a second plate mated to the first plate by at least one mechanical fastening mechanism. The fixture assembly further includes a space defined by facing surfaces of the first plate and the second plate and confined by a raised stepped portion of at least one of the first plate and the second plate. The space is coincident with the opening. The space is sized and shaped such that the laminate is confined within the space and directly abuts the stepped portion and the facing surfaces of the first plate and the second plate to be confined in X, Y and Z directions.
