  • Patent number: 6552263
    Abstract: The electrical interconnections between an integrated circuit chip assembly are encapsulated and reinforced with a high viscosity encapsulant material in a single step molding process wherein a mold is placed over an integrated circuit chip assembly and encapsulant material is dispensed through an opening in the mold and forced around and under the integrated circuit chip by external pressure encapsulating the integrated circuit chip assembly. An integrated circuit chip assembly having a reinforced electrical connection which is more resistant to weakening as a result is stress created by differences in coefficient of thermal expansion between the integrated circuit chip and the substrate to which the integrated circuit chip is attached is produced.

  • Patent number: 6387205
    Abstract: A method for coating cloth especially fiberglass sheets with a thermosetting resin and resulting structure is provided. The coating is performed in two steps. In the first step, essentially all of the strands of the fiberglass are coated with the resin/solvent mixture while maintaining at least some of the interstices or openings essentially free of the solvent mixture. This first coating is then partially cured to between about 70% and 90% of full cure. The coated fiberglass with partially cured resin thereon is then given a second coating of either the same or different thermosetting resin mixture which coats the first coating and fills in the interstices between the fibers. This second coating is then partially cured, which advances the cure of the first coating past 80% full cure and results in an impregnated fiberglass cloth structure for use as sticker sheets.

  • Patent number: 6369449
    Abstract: The electrical connections of an integrated circuit chip assembly comprised of an integrated circuit chip attached to a substrate are encapsulated and reinforced with a high viscosity encapsulant material by dispensing the encapsulant material through an opening in the substrate into the space between the integrated circuit chip and the substrate. An integrated circuit chip assembly having a reinforced electrical interconnection which is more resistant to weakening as a result of stress created by differences in coefficient of thermal expansion between the integrated circuit chip and the substrate to which the integrated circuit chip is attached is produced.

  • Patent number: 6096665
    Abstract: A method for coating cloth especially fiberglass sheets with a resin and resulting structure is provided. The coating is performed in two steps. In the first step, essentially all of the strands of the fiberglass are coated with the resin solvent mixture as well as most of the interstices or openings, although some of the interstices or openings have holes where the coating does not completely fill in. This first coating is then partially cured to the extent that it will not redissolve in a second coating of the same resin solution. The coated fiberglass with partially cured resin thereon is then given a second coating of the same resin mixture which coats the first coating and fills in any holes in the first coating. This second coating is then partially cured, which advances the cure of the first coating and results in an impregnated fiberglass cloth structure for use as sticker sheets. This substantially reduces pinholing.

  • Patent number: 5919525
    Abstract: A method and resultant article are provided which optimize the adhesion of resin to the glass fibers in fiberglass cloth impregnated with a resin and also optimize the adhesion of the impregnated resin to metal sheets laminated to the resin-impregnated cloth. The fiberglass is treated in two or more passes. On the first pass, the fiberglass is impregnated with a first resin which is optimized for adherence to glass fibers and the coated resin is partially cured. In a last pass, the fiberglass is impregnated with a second resin, which is different from said first resin, and is optimized for bonding to metal. The second resin is then partially cured. The first and second resins are selected such that they form a bond with each other when cured.
