Kulicke & Soffa 4523 Wire Bonder
The bonder can be operated in auto cycle or manual mode. The auto cycle mode is the preferred mode
for most applications. Stitch bonding can be performed in the auto cycle mode. The manual mode is
useful when the elevation between subsequent bond-pairs is substantially different. Instructions for the
two modes are detailed below.
Auto Cycle Bonding
Auto cycle bonding is the preferred mode for most bonding applications.
1. If your application requires heat, set the temperature controller.
a. Push set once
b. Push up and down to set the correct value
*NOTE* Setpoint II does not work for this model
2. Set the SEMI AUTO/MAN Z switch on the right side of the panel to SEMI AUTO.
3. Set the RESET LEVEL switch to the preferred setting (high or low) and verify that the CLAMP
switch is in the down position.
4. Set the POWER, TIME, and FORCE bonding parameters for the first and second bonds. The top
row is for the first bond and the bottom row is for the second bond.
5. Set the LOOP height. This is the height the bonding wedge will go to after the first bond.
6. Set the TAIL parameter. Longer tail lengths are useful to help prevent unthreading of the wedge
tip. A value of 6 is appropriate for most applications.
7. Adjust the search height for the first bond.
a. Set the SEARCH height dial for the first bond to 10.
b. Move over the first bond pad and hold down the RIGHT mouse button.
c. Adjust the SEARCH height dial until the bonding tip is just above the bond pad.
d. Release the RIGHT mouse button to make the first bond.
8. After the first bond, the bonding head moves to the LOOP height. Adjust the LOOP dial if
needed.
9. Adjust the SEARCH height for the second bond using the bottom SEARCH dial and the same
procedure as in 7.
10. Subsequent bonds are made by holding the RIGHT mouse button to lower the bonding head to
the SEARCH height, positioning the bonding head, and releasing the RIGHT mouse button to
perform the bonding action.
To stitch multiple bonds, hold the LEFT mouse button while performing step 10. The stitching
terminates once the LEFT mouse button is released and a normal, “second” bond has been completed.
Manual Z Bonding
This mode allows you to manually control the bonding head.
1. If your application requires heat, set the temperature controller.
a. Push set once
b. Push up and down to set the correct value
*NOTE* Setpoint II does not work for this model
2. Set the SEMI AUTO/MAN Z switch on the right side of the panel to MAN Z.
3. Set the RESET LEVEL switch to the preferred setting (high or low).
4. Set the POWER, TIME, and FORCE bonding parameters for the first and second bonds. The top
row is for the first bond and the bottom row is for the second bond.
5. Set the LOOP height. This is the height the bonding wedge will go to after the first bond
6. Set the TAIL parameter. Longer tail lengths are useful to help prevent unthreading of the wedge
tip. A value of 6 is appropriate for most applications.
7. Lower the bonding head above the first bond location using the MANUAL Z tab and adjust the
position using the mouse.
8. Once the bonding head is properly positioned above the desired location, continue to lower it
until it touches the bonding pad.
9. Press the RIGHT mouse button to perform the first bond.
10. Slowly release the MANUAL Z control and the bonding head will go the LOOP height.
11. Repeat steps 7-9 to perform the second bond.
