  • Patent number: 11245075
    Abstract: An organic substrate and method of making with optimal thermal warp characteristics is disclosed. The organic substrate has one or more top layers and one or more bottom layers. A chip footprint region is a surface region on each of the top and bottom layers that is defined as the projection of one or more semiconductor chips (chips) on the surface of each of the top and bottom layers. One or more top removal patterns are located on and may or may not remove material from the surface of one or more of the top layers within the chip footprint region of the respective top layer. One or more bottom removal patterns are located on and remove material from the surface of one or more of the bottom layers outside the chip footprint region of the respective bottom layer. The removal of the material from one or more of the top layers and/or bottom layers changes and optimizes a thermal warp of the organic substrate.

  • Patent number: 7741834
    Abstract: Method for detecting and reporting a condition. The components of the invention include an electronic package having a substrate with electrically conducting lines electrically connected to an integrated chip, and to a source of voltage. The integrated circuit chip is mounted onto a substrate and electrically connected to at least one electrically conducting line. A sensor, combined with a signal generator, connected to the substrate, is operable to generate an electrical signal upon detection of a condition selected from a condition of the substrate and a condition of an electrical connection to the substrate. The signal generator, after immediately receiving the aforesaid electrical signal from the sensor, emits the warning signal. The warning signal of indicated of an existing defect or a condition which can lower the longevity of the total electronic package.

  • Publication number: 20080064143
    Abstract: A microelectronic device is made of a semiconductor substrate, a heat generating component in a layer thereof, and a body within the remaining semiconductor substrate. The body is made of materials which have a high thermal inertia and/or thermal conductivity. When high thermal conductivity materials are used, the body acts to transfer the heat away from the substrate to a heat sink.

  • Publication number: 20060098399
    Abstract: Embodiments of the present invention pertain to method for manufacturing a shock absorber that allows a disk drive to move with respect to the chassis of a computer system. In one embodiment, a flexure is formed that is capable of being coupled to an assembly joint. An assembly joint is formed so that the assembly joint is capable of being coupled to the flexure and the chassis of a computer system. A shock absorber is created by coupling the flexure to the assembly joint. The shock absorber has a form that can be used to flexibly couple the disk drive's enclosure with the computer system's chassis without requiring an increase in size of the chassis.
