"WebAu-Al ball bonding generally takes place at 200-240 deg C. In cases where the wire and bond pad have similar metallurgies, bonding may occur at ambient temperature, such as in the case of aluminum wedge/aluminum bond pad bonding. Pressure is applied to the bonding tool to keep it in control as it scrubs the bond against the bond pad. " - Gold wire imc
