"The Westbond model 7400A is an ultrasonic/thermosonic
wedge-wedge wire bonder designed to interconnect wire
leads to semi-conductor, hybrid or microwave devices.
The machine bonds aluminum or gold wires ranging from
0.0007 in. to 0.002 in. Bonds are made by
the wedge-wedge technique using ultrasonic energy to
attach aluminum wire at room temperature and
adding work piece heat for gold wire.
Wire is clamped and threaded diagonally under the
bonding wedge, allowing independent feeding action but
requiring front-to-back bonding direction.
The bonding tool is lifted and lowered manually by
the operator usind hand/eye reference to
the work elevations and to loop height."
