Aluminium Wires Have the Free Air Balls (FABs): Electronic Flame-Off, Fracture Strength, Electrical Properties, and Bonding Characteristics of Nano Zn Film Al–Si Bonding Wires
Abstract
:1. Introduction
2. Experiment
3. Results and Discussion
4. Discussion
- (1)
- Currently, Al wires cannot be used in wire bonding with ball bonding; however, coating Al–0.5 wt % Si wire with a Zn film with 80–250 nm can improve this problem. Further, the mechanical properties, bonding strengths and bias tensile strength of the 20 μm Zn-coated Al–0.5 wt % Si (ZAS) wires are stable.
- (2)
- Pores in the 80 nm ZAS wire FAB have no influence on bonding characteristics. Moreover, the low interface resistance, high fusing current, and excellent aging surface of the 80 nm ZAS wire hold potential for application in IC packaging.
