Web12 jun. 2024 · Approximately 90% of all IC Assembly in Semiconductor Packages is manufactured using Gold Ball Bonding process, while Aluminum Wedge Bonding is … WebWire Bonding - is done to the Ni surface. The wire goes through the thin Pd (up to 0.25µ) and makes a NiAu intermetallic. Whereas in Ag spot plated leadframes, wire bonding is done to the Ag surface, a relatively thick, soft substrate. The differences in wire bonding mechanics have implications for capillary design and bonding parameters.
