MPP & KnS Adjusting Bond Force Settings

During the bonding cycle, bond force is applied while ultrasonic energy is been applied to the wedge/capillary. The static bond force is a combination of the Static Bond force and also additional bond force applied from the Force coil.

45xx Series:

The Force coil is controlled via the 1^st Bond and 2^nd Bond potentiometer dials on the left hand side front panel:

iBond5000 Series:

The Force coil is controlled via 1^st and 2^nd Bond Force adjustment on the touch screen panel:

To Set the Bond Force:

Ensure the Bonder is in Reset Position; confirm this by ensuring the ‘1st Bond LED’ is illuminated (4500 series) or ‘Reset Position’ is displayed in the status window (iBond series).
The ‘Set Up/Reset’ switch located on the right hand side panel (4500 series) or ‘Setup’ slider within the iBond5000 menu section (iBond series) are showing SETUP.
With the bonder in SETUP the machine will drive the Force Coil constantly at both 1st and 2nd bond forces depending on the machine cycle position.

Set both 1st and 2nd Search adjustment to zero.
Press and hold the ‘Semi/Auto Chessman button’. The bond head will move into the ‘1st Search height’.
Using a suitably scaled gram gauge lift the bond head under the wedge/capillary. As the bond head starts to rise, read the value on the gram gauge.
This measured value is the bond force for the 1st Bond; adjust the ‘1st Bond Force adjustment’ until a desired force is measured on the gram gauge.
Release the ‘Semi/Auto Chessman button’, the bond head will move to the ‘Loop Height’.
Press and hold the ‘Semi/Auto Chessman button’. The bond head will move into the ‘2st Search height’. Again, lift the bond head with the gram gauge under the wedge/capillary until the bond head starts to rise.
This measured value is the bond force for the 2nd Bond; adjust the ‘2nd Bond Force adjustment’ until a desired force is measured on the gram gauge.
Release the ‘Semi/Auto Chessman button’, the bond head will move to the ‘Reset Height’.
Return the ‘Set Up/Reset’ switch to the mid position.
