West Bond 4KEX Semi-Automatic

West Bond 4KEX Semi-Automatic, Motorized Y/Z Axes,
Wedge-Wedge, Ball-Wedge Convertible Large Substrate Wire Bonder.
Series 4KE models are three-way convertible Semi-Automatic wire bonders of a gantry design. The entire mechanism is arrayed above
the work plane, so that it is wide open to accommodate different size
and style of work packages.
Two-axes X and Y are driven manually by unique West·Bond micro-
manipulator for positioning. Microprocessor controlled W
(in Y direction) and Z axes are driven by program controlled motors
to arch the connection. It is capable of creating a series of parallel,
single or multiple arched wires while maintaining identical loop
and bond shapes. Cross roller bearings rigidly guided axes are moving orthogonally, with independent pneumatic brakes in
X and Y applied on signal. Target the critical bond location manually
with the manipulator via moving the crosshairs generated on
the screen and image captured from vertical view CCTV camera,
then the target will be secured by the brakes to proceed
with programmed bonding. A dual force mechanism,
operated pneumatically, acts to change between two pre-set
force values, and either high or low force may be programmed for
any bond. Radiant tool heat with panel mounted, controlled by
constant current. With simple exchange of clamp assemblies,
bond tool, and wire path provided with the software mode will
allow quick conversion between conventional 45º wire feed,
deep access wire or ribbon, ball bonding, insulated wire and
single point tab / lead bonding. All programmed bond variables as
well as machine settings for each bond mode are retained in
the machines memory. Bond Force: 10 – 150 grams;
(High / Low programmable).
Au / Al: 0.7 to 3 mil, Ribbon: 0.5x2 to 1x10 mil,
Au Ball Bonding: 0.7 to 2 mil.
This unit has a larger 20" x 20" work platform
and a 6" x 8" heated work holder.
Can do large substrates or small standard size sustrates.
