  • Patent number: 9865556
    Abstract: A semiconductor device has a semiconductor die with a die bump pad and substrate with a trace line and integrated bump pad. Conductive bump material is deposited on the substrate bump pad or die bump pad. The semiconductor die is mounted over the substrate so that the bump material is disposed between the die bump pad and substrate bump pad. The bump material is reflowed without a solder mask around the die bump pad or substrate bump pad to form an interconnect. The bump material is self-confined within a footprint of the die bump pad or substrate bump pad. The bump material can be immersed in a flux solution prior to reflow to increase wettability. Alternatively, the interconnect includes a non-fusible base and fusible cap. The volume of bump material is selected so that a surface tension maintains self-confinement of the bump material within the bump pads during reflow.

  • Patent number: 9831572
    Abstract: A socketless land grid array (LGA) is provided that uses an adhesive material rather than a socket to secure the optical communications module to the LGA and to provide the clamping force that is needed to maintain contact between the module and the LGA and to maintain a flat profile for the module and the LGA. Eliminating the LGA socket eliminates the need to drill holes in the host circuit board and the need for additional hardware (e.g., backing plates, screws, etc.) to secure a socket to the host circuit board. This allows the area of the host circuit board underneath the array of electrical contacts of the LGA to be used for routing electrically-conductive pathways of the host circuit board (e.g., vias and traces) and reduces the amount of time and effort that are needed to secure modules to the respective LGAs.

  • Patent number: 8740041
    Abstract: A brazing ring with integrated fluxing product and methods for production thereof is described. The brazing ring has a c-shaped body with a plurality of channels extending the thickness of the ring and disposed about the circumference thereof. The channels are separated by radially extending flanges with enlarged distal ends that extend into the channels. The enlarged ends at least partially enclose the channels to aid in retention of a fluxing product disposed in therein. The c-shape may enable flexure of the ring for installation on a pipe or fitting and a friction fit to maintain an installed position. The brazing ring is formed by extruding a filler material to form a tube with the desired profile and compressing the fluxing product into the channels of the profile. The tube is subsequently sectioned perpendicularly to its length to produce a plurality of the brazing rings.

  • Patent number: 8733620
    Abstract: A solder is deposited on a heat sink. The solder is first reflowed at a first temperature that is below about 120° C. The solder is second heat aged at a temperature that causes the first reflowed solder to have an increased second reflow temperature. The heat aging process results in less compressive stress in a die that uses the solder as a thermal interface material. The solder can have a composition that reflows and adheres to the die and the heat sink without the use of organic fluxes.
