West Bond 7400A Thermosonic Vertical Feed Deep Access Wedge Wire Bonder

This West-bond 7400A Manual
Ultrasonic/Thermosonic 90° Vertical Feed Deep
Access Wedge-Wedge Wire Bonder looks to
be in good cosmetic condition, showing some signs of wear.

The label lists the model number as "7416A,"
which is a Thermocompression Wedge Bonder,
but this machine has obviously been modified to
be a 7400A Thermosonic Wedge Bonder.

It currently has Tool Heat, Adjustable Height Platform,
and 1/2" & 2" Wire Spools installed, as shown.

It comes with everything shown,
including an Ultrasonic Generator,
a B&L SZ4 StereoZoom 4 Microscope
(0.7X to 3.0X) with eyepieces, and a Heated Workholder with
Temperature Controller, as shown
(the microscope, generator and workholder/controller shown
in the photos above are not necessarily the exact ones you
will receive; they are shown merely to
represent what a complete system will look like).

Approximate overall unpacked dimensions: 24"L x 21"W x 14"H.

"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."
