West Bond
4546E
The West Bond 4546E is a semi-automatic wedge wire bonder. The West Bond 4546E uses ultrasonic energy to bond wire leads between wafer dies and contact pads of electronic packages. The West Bond 4546E is typically configured for 1 mil (25 μm) Al wire in a wedge bonding configuration.[1][2][3]
