  • Wire bonding capillary
    Patent number: 6325269
    Abstract: A wire bonding capillary (1), which is able to decrease wire extraction resistance and suitable for a long and low loop wire bonding process, comprises a through bore (5) for feeding a bonding wire, a funnel-shaped bore (3) for guiding the wire to the through bore, and a tapered portion (11) formed at an exit of the through bore. The through bore length is between 0.2 and 1.5 times the through bore diameter. The tapered portion is tapered in two steps.

  • Fluorine-containing elastomeric copolymers, process for preparing the same and composition containing the same
    Patent number: 4141874
    Abstract: Elastomeric copolymer of vinylidene fluoride and at least one other fluorine-containing monomer containing 28 to 92% by mole of the vinylidene fluoride unit and having an intrinsic viscosity of 0.4 to 1.3 at 35.degree. C. in methyl ethyl ketone, which is prepared by a two-stage polymerization process of vinylidene fluoride monomer and at least one other fluorine-containing monomer wherein monomers are copolymerized in an aqueous medium in the presence of a water-soluble radical polymerization initiator at a first stage to give a first stage-copolymer having an intrinsic viscosity of 0.01 to 3.0 at 35.degree. C.
