  • Publication number: 20150246411
    Abstract: Provided is a wire-bonding apparatus 10 including a capillary 28 through which a wire 30 is inserted, a nonsticking determination circuit 36, and a controller 80. The nonsticking determination circuit 36 applies a predetermined alternating-current electrical signal between the wire held by the capillary and the bonding target, obtains a capacitance value between the wire held by the capillary and the bonding target, determines that the wire is disconnected from the bonding target when the capacitance value decreases after the first bonding operation, and determines that the disconnected wire drops down and is brought into contact with the bonding target when the capacitance value returns to an original value before reaching the second bonding point.

  • Patent number: 8742602
    Abstract: A die assembly includes a die mounted to a support, in which the support has interconnect pedestals formed at bond pads, and the die has interconnect terminals projecting beyond a die edge into corresponding pedestals. Also, a support has interconnect pedestals. Also, a method for electrically interconnecting a die to a support includes providing a support having interconnect pedestals formed at bond pads on the die mount surface of the support, providing a die having interconnect terminals projecting beyond a die edge, positioning the die in relation to the support such that the terminals are aligned with the corresponding pedestals, and moving the die and the support toward one another so that the terminals contact the respective pedestals.

  • Publication number: 20130224198
    Abstract: A recombinant fusion protein comprising a human erythropoietin peptide portion linked to an immunoglobulin peptide portion is described. The fusion protein has a prolonged half-life in vivo compared to naturally occurring or recombinant native human erythropoietin. In one embodiment, the protein has a half-life in vivo at least three-fold higher than native human erythropoietin. The fusion protein exhibits enhanced erythropoietic bioactivity compared to native human erythropoietin. In one embodiment, the fusion protein comprises the complete peptide sequence of a human erythropoietin (EPO) molecule and the peptide sequence of an Fc fragment of human IgG1, which Fc fragment includes the hinge region, CH2 and CH3 domains. The EPO molecule may be linked directly to the Fc fragment to avoid extraneous peptide linkers and lessen risk of an immunogenic response when administered. In one embodiment the hinge region is a human Fc fragment variant having a non-cysteine residue at amino acid 6.
