Abstract

Wire bonding is a primary method of making interconnection between an integrated circuit (IC) and a printed circuit board (PCB) during semiconductor device fabrication, which is generally considered as the most flexible and cost-effective interconnection technology, and is widely used in electric packaging. This paper focuses on the impedance mismatch problem caused by bonding wires. A variety of bonding wires with different characteristics in terms of diameter, loop span, loop height, and shape are studied in this paper. Additionally, the crosstalk between adjacent bonding wires is analyzed. All analysis is founded on the base of signal integrity theory and simulation with HFSS software.
