Tip compensation

Tip compensation involves the automatic detection and measurement of the dispensing tip position on all three coordinate axes: X, Y and Z. For this purpose, a mechanical touch point is set to measure the length of the tip. The positional deviation in the X and Y directions is determined using one WFL precision laser fork photoelectric sensor for each axis, and the corresponding offset is automatically compensated in the system. This results in increased process reliability and decreased downtime following a changeover involving materials or tips.
