Dwell Time
Dwell Time measures how long the dispensing head stays at the final position after the end of dispensing before retracting.
This may be necessary to give the fluid a chance to detach from the tip and onto the substrate, i.e. increasing the Dwell
Time can reduce “stringing” of material.
The units are in seconds. Typically, 0 - 20 ms (0.020 sec) is sufficient.
Reverse Time
This parameter is only required when the 790 Auger Valve has been selected in the Setup mode. At the end of dispensing a
dot, the valve is reversed for the specified time period to remove any material from the tip of the needle. The Reverse Time
value should be set according to fluid/paste viscosity. Generally, 10 ms (0.010 sec) is sufficient.
Backtrack Gap
This is the vertical distance that the dispensing head moves up after completion of a move. At the end of a move, the
dispensing head is raised up by the amount set in the Backtrack Gap, before moving the Backtrack Length back over the line
that was just dispensed. This encourages congealed fluids to detach and distributes any excess fluid back across the line.
The units are either in inches or millimeters. Backtrack Gap should be at least double the Dispense Gap.
