What it is
How it works
The West Bond 7700E uses an optical encoder in the Z axis to track vertical tool motion and measure the elevation above each bond at which ball formation begins. The machine uses a motor-shaft-mounted spiral cam to drive the clamps and feed an exact new length of wire, and the machine discharges a controlled quantity of electrical energy to the free wire end to form the ball.[1]
The 7700E accommodates gold wire and uses bonding tools with a one-sixteenth-inch shank diameter and a tool length of 0.625 inch or 0.750 inch for deeper access.[1]
Where it fits in the process flow
The West Bond 7700E is used to connect wire leads to semiconductor, hybrid, or microwave devices. The machine includes a work station with an adjustable height platform and a rotary platform as an available feature for rotating work about the center of the tool X-Y range.[1]
Applications
The West Bond 7700E is used for thermosonic gold-wire bonding. The machine is intended for semiconductor, hybrid, and microwave device interconnection.[1]
- Interconnecting wire leads to semiconductor devices
- Interconnecting wire leads to hybrid devices
- Interconnecting wire leads to microwave devices
