INSTALLATION
Adjusting the Camera Focus
The camera focus is set at the factory before shipment. Unfortunately, the bumping and jarring that the
machine encounters during shipment may upset this delicate adjustment. A slight adjustment may be
required to bring the camera back into factory specifications. Below you will find a detailed set of
instructions to effect this adjustment. W
EST•BOND recommends reading all of the steps prior to attempting
any adjustment. This is to familiarize the operator with the camera configuration, allowing for a quicker
and more effective adjustment process. If you encounter any difficulties or have any questions, feel free
to contact W
EST•BOND or your local factory representative technical support for help.
S
TEP 1 - SETTING THE WORK HEIGHT
Place the package (a.k.a. the part to be bonded) upon its workholder and refer to page 28 to correctly set
the W
ORK HEIGHT. When this is properly set, there will be a 5 inch differential between the bottom edge of
the platform and the top of the bonding surface.
S
TEP 2 – INCH DOWN AND BOND OFF
From the home menu (A
LIGN BOND MENU) press key 6 to go to the THREAD AND BOND menu. Using the G
key, look into the microscope, inch down onto your work surface, and bond off. In this mode all of the
machine’s brakes will lock in order to keep the bonding surface underneath the camera eye.

of a turn. This nut simply locks up the camera adjustment and it is not
necessary to loosen it excessively. Located in the top of the adjustment block, above the T
HUMB NUT is
the CAMERA Z-ADJUSTMENT SCREW. Insert a

” Allen wrench and turn slowly while observing the bonding
surface in the monitor. Turning this screw clockwise will raise the camera assembly while counter-
clockwise will lower it. Once the optimum focus is achieved, lock down the thumb nut and press the A
key. Bond off again and set the crosshairs.

STEP 4 – SETTING THE CROSSHAIRS
Use the digi-switches on the crosshair generator to move the crosshairs up and down or left and right. If
the bond did not stick then the operator may choose to bond again by pressing the A key or, if everything
is correct, key G may be pressed to accept the crosshair settings. If the bond is outside of the camera
screen it may be necessary to adjust the camera position and bring the bond back into the center of the
screen.
S
TEP 5 – ADJUSTING CAMERA POSITION
First, using the digi-switches on the crosshair generator set the cross hairs to target directly in the center
or lower center of the screen (placement of the crosshairs in the lower center of the screen will allow the
operator to see both first and last bond if they are close together). Next, ensure that the camera head is
square with the body of the camera. Looking from the right side of the machine you can look down the
side of the camera head and the camera body. If these two are not square with each other the onscreen
image may appear to be rotated in comparison to the image seen through the microscope.. Once these
two are aligned, locate the D
UTCH KEY SCREW holding the OPTICS TUBE ASSEMBLY. Insert a
7
/
64
” Allen
wrench into the socket head screw and loosen
1
/
2
turn. Do Not Remove This Screw! When this screw is
loosened it will allow the optics tube to rotate and slide left and right. Using these two adjustable axis
position the crosshairs over the bond. Snug down the D
UTCH KEY SCREW. Do not over tighten this screw.
At this point it may be necessary to readjust the focus as outlined in step 3. If the focus is ok, then bond
off again and make any small final adjustments to the crosshairs.
N
OTE! This is a delicate procedure that may require a bit of finesse and patience. Once this
camera is properly set up, a re-adjustment need not be performed unless the camera
head is knocked or jarred.
The 454647E is now ready for operation. Please refer to the next section to understand several
important aspects of successful wire bonding with the 454647E.

MACHINE CONTROLS
Front Panel
The 454647E Semi-Automatic Wire Bonder has been specifically designed to be versatile, dependable,
and easy to use. To effect this end, the following sections have been developed to help the operator take
advantage of its advanced bonding features. A in-depth study and understanding of this section will result
in better bonds, higher gram pulls, and faster set up times.
P
OWER SWITCH
Activates entire 454647E. Upon power-up, the microprocessor will complete several internal tests
and display a description of any problem detected. Refer to the Troubleshooting section (page
99) if an error is reported.
R
ESET SWITCH
When pressed, the machine re-homes all motor positions and returns the user to the home menu.
This button should be pressed once before the power is turned off. This prevents the tool head
from “snapping” back into the home position if it is down at search height when the power is
turned off.
T
OOL HEAT
See page 107 for dial settings and the corresponding temperature.
I
NTENSITY
This knob controls the available amount of camera backlighting. In bright (white surfaced)
packages this backlight is unnecessary and is difficult to even notice. However, in a dark or deep
package this option can greatly increase the visibility of the bonding pads.
