Method and system for pull testing of wire bonds

A method for pull testing a wire bond. The method including the steps of: (i) with a wire bonding tool, bonding an end of a wire to make a bond at a first location on a bonding surface having a conductive material, such that the bond completes an electrical circuit; (ii) clamping the wire with a wir...

Zusammenfassung:A method for pull testing a wire bond. The method including the steps of: (i) with a wire bonding tool, bonding an end of a wire to make a bond at a first location on a bonding surface having a conductive material, such that the bond completes an electrical circuit; (ii) clamping the wire with a wire clamp; (iii) pulling the wire with the wire clamp to apply a predetermined pulling force; (iv) detecting whether the electrical circuit is open; and (v) if the electrical circuit is open, determining that there has been a bond failure, and automatically incrementing a bond failure count.
