Chapter A: Wire Bonding 2 Level 2. Conclusions and guideline

gold wire (< 75 µm) is mostly used in this technique because of its easy deformation under pressure at elevated temperature, its resistance to oxide formation, and its ball formability during a flame-off or electronic discharge cutting process. Ball bonding is generally used in application where the pad pitch is greater than 100 µm.
