WebENEPIG is frequently requested for applications requiring wire bonding as it demonstrates high wire bond pull strengths: aluminum wire up to 10g, gold wire up to 8g. It is also a very thin PCB finish (between 0.05μm and … 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. signs of dehydration nausea
