WebGold wire is the preferred material in thermosonic and thermocompression gold wire bonding. But the material must be clean and have a smooth surface finish to ensure sufficient adhesion and no clogging along the capillary chamfer diameter. However, ultra-pure gold is very soft. Therefore, small quantities of beryllium (5-10 ppm) or copper (30 ... WebBall bonding. Ball bonding is a type of wire bonding, and is the most common way to make the electrical interconnections between a bare silicon die and the lead frame of the package it is placed in during semiconductor device fabrication . Gold or copper wire can be used, though gold is more common because its oxide is not as problematic in ... capital bank of jordan + ceo
