Height Sensor Failure
A. Introduction
The HS-Series RT Height Sensor uses a stainless steel probe to contact the dispensing
surface. The probe tip is machined to minimize surface contact. The LK-Series Laser
Height Sensor uses a semiconductor laser beam and triangulation measurement to
determine the substrate height. As the dispensing head lowers, the laser beam reflects off
of the substrate surface back up to sensing array inside of the Height Sensor. The
following section identifies some possible Height Sensor problems and their solutions.
B. Enabling Objective
4.9 Identify Height Sensor Troubleshooting procedures and perform procedure to
remove and replace Height Sensor Probe.
