  • Patent number: 7510324
    Abstract: A method of inspecting articles using an imaging inspection apparatus which utilizes a plurality of individual imaging devices for directing beams onto the articles having objects therein to detect the objects based on established criteria. The method involves the enhanced cooling of the heat-generating imaging devices in which a fan directs cooling fluid onto a plurality of deflectors which in turn direct said fluid onto selected ones of said imaging devices.

  • Patent number: 7510912
    Abstract: A method of making a wirebond electronic package which includes a semiconductor chip bonded to the upper surface of an organic laminate substrate, including to a thermal material located on the substrate and comprised of a plurality of thermally conductive concentric lines. These lines form paths of heat escape for the chip during operation thereof and may operate in combination with other elements to extend the heat paths. Concentric lines also assure sufficient bonding area on the substrate so as to prevent delamination of the chip from the substrate as may occur during high temperatures associated with subsequent processing such as solder ball re-flow.

  • Publication number: 20080029888
    Abstract: A method and article of fabrication is described featuring a solder layer having a serpentine, interrupted, or interdigitated boundary. The non-planar design of the boundary layer increases the fatigue life of the solder joint by limiting the damage caused by micro-cracking. This irregularity of the solder boundary constrains the propagation of cracks by creating obstacles along the crack path, redirecting the crack away from the intermetallic layer, or by increasing the path along which the crack propagates.

  • Patent number: 6788859
    Abstract: A method and an article made by a method for embedding optical fibers into an organic laminate structure. The optical fiber cabling, along with its cladding, is placed upon a first laminate layer that includes a composite made of silica fillers and a frictionless material such as polytetrafluoroethylene (PTFE). Then a second layer of PTFE material with silica fillers and copper sheeting is placed on top of the PTFE with silica fillers composite. The PTFE material with silica fillers flows about the optical fibers at a temperature approximately fifty degrees above the PTFE with silica fillers material's melting point. This procedure completely encases the optical fibers within an opaque sheath.
