  • Stud bump for wirebonding high voltage isolation barrier connection
    Patent number: 11973052
    Abstract: An electronic device includes a bond wire with a first end bonded by a ball bond to a planar side of a first conductive plate, and a second end bonded by a stitch bond to a conductive stud bump at an angle greater than or equal to 60 degrees. A wirebonding method includes bonding the first end of the conductive bond wire to the first conductive plate includes forming a ball bond to join the first end of the conductive bond wire to a planar side of the first conductive plate by a ball bond, and bonding the second end of the conductive bond wire to the conductive stud bump includes forming a stitch bond to join the second end of the conductive bond wire to the conductive stud bump.
