  • Publication number: 20090078740
    Abstract: A wirebonder for electrically connecting an integrated circuit die with conductors on a printed circuit board. The wirebonder has a bonding tool for attaching wire bonds from the integrated circuit die to the conductors of the printed circuit board and a wire engaging structure for deforming the wire bonds such that they have a flatter profile shape.
    Type: Application

  • Publication number: 20090079097
    Abstract: An electronic component that has a support structure with a plurality of electrical conductors, a series of wire bonds, each of the wire bonds extending from one of the electrical conductors respectively, each of the wire bonds having an end section contacting the electrical conductor and an intermediate section contiguous with the end section, a bead of dam encapsulant encapsulating the electrical conductors and the end section of each of the wire bonds, and a bead of fill encapsulant contacting the bead of dam encapsulant and encapsulating the intermediate portion of each of the wire bonds. The dam encapsulant has a higher modulus of elasticity than the fill encapsulant.

  • Publication number: 20090081829
    Abstract: A method of reducing wire bond loop heights in wire bonds electrically connecting an integrated circuit die with a contact pad to a printed circuit board with a conductor, by mounting the integrated circuit die such that the contact pad is spaced from the conductor, positioning an adhesive surface between the contact pad and the conductor on the printed circuit board, attaching wire to one of the contact pad or the conductor, drawing the wire towards the other of the contact pad or the conductor, allowing the wire to contact the adhesive surface, and, attaching the wire to the other of the contact pad of the conductor to form a wire bond adhered to the adhesive surface and a point intermediate its ends.
