Abstract
A system for cleaning bond wire for use by a wire bonding machine includes a bond wire supply station, a bond wire cleaning bath station, a bond wire neutralizing station, a bond wire drying station, and a wire bonding machine. In operation, the bonding machine is supplied with bond wire stored at the supply station, which is firstly de-oxidized with a cleaning solution in the cleaning bath station. Next, the cleaning solution on the bond wire is neutralized with a neutralizing liquid in the neutralizing station. The bond wire is then dried in the drying station. The speed of the bond wire passing through the cleaning bath station, neutralizing station and drying station is controlled by the wire bonding machine.

A system for cleaning bond wire for use by a wire bonding machine, the system comprising:
- a bond wire supply station;
- a bond wire cleaning bath station;
- a bond wire neutralizing station;
- a bond wire drying station;
- and
- a wire bonding machine,
- wherein in operation the cleaning bath station is supplied with bond wire stored at the supply station that is firstly de-oxidized with a cleaning solution in the cleaning bath station and then the cleaning solution on the bond wire is neutralized with a neutralizing liquid in the neutralizing station and then the bond wire is dried in the drying station,
- wherein the speed of the bond wire passing through the cleaning bath station, neutralizing station and drying station is controlled by the wire bonding machine, and
- wherein the neutralizing station includes dispensing outlets for dispensing the neutralizing liquid onto the bond wire, a reservoir for collecting the neutralizing liquid dispensed from the dispensing outlets, and a pump and conduit for re-cycling the neutralizing liquid back to the dispensing outlets.

A method of cleaning a bond wire supplied from a bond wire supply station to a wire bonding machine, the method comprising:
- de-oxidizing the bond wire, supplied from the supply station, in a cleaning bath station with a cleaning solution;
- neutralizing the cleaning solution on the bond wire by dispensing a neutralizing liquid onto the bond wire with dispensing outlets, wherein the neutralizing liquid dispensed from the dispensing outlets is collected by a reservoir and re-cycled back to the dispensing outlets by a pump and conduit;
- drying the bond wire in the drying station to provide a de-oxidized bond wire;
- and
- using the de-oxidized bond wire in a wire bonding machine, wherein the speed of de-oxidizing, neutralizing, and drying the bond wire is controlled by the wire bonding machine.
