About machine
West Bond Wedge wire bonder bond aluminum or gold wires from 0.0007 in. to 0.002 in. diameter by the wedge-wedge technique using ultrasonic energy to attach aluminum wire at room temperature and adding workpiece heat for gold wire. The wire is fed to the work point by two methods selectable by the exchange of wire clamps, either diagonally through the heel of the bonding wedge or vertically down through a hollow wedge. Either allow programmed motions to clamp, break, and feed wire continuously but requires front-to-back bonding direction.
