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. WebAnother advantage of flip chip is the absence of bonding wire reducing signal inductance. An essential process for flip chip packaging is wafer bumping. Wafer bumping is an advanced packaging technique where ‘bumps’ or ‘balls’ made of solder are formed on the wafers before being diced into individual chips. orbis nedir
