Slim Line Height Sensor
 The
Slim Line retractable height sensor from Asymtek® compensates
for variations in substrate flatness in order to maintain a consistent
dispense height throughout the dispense cycle. It is ideal for dot
and line applications where dispensing height accuracy is critical.
When the dispense head is lowered toward the workpiece to begin
dispensing, a stainless steel touch probe extends and gently contacts
the work surface. The probe triggers an optical sensor that causes
the dispense head to decelerate its downward (Z-axis) movement,
bringing the dispensing valve's needle to its programmed dispensing
height above the workpiece. After performing the height sense, the
probe retracts and the dispensing cycle begins.
Users can operate the Slim Line Height Sensor in different retract
modes, using Asymtek's Fluidmove®
for Windows NT®
software. The probe can be reconfigured to retract after each height
sense, or to sense at every dispense point.
The probe applies only 7 grams of force as it contacts the substrate.
The low force minimizes substrate flexure and vibration, and avoids
damage to delicate substrates. Other types of probes may be used
when appropriate. The probe is easy to rotate out of the way for
needle tip changes.
Features
- Retractable probe for dispensing in wells
or densely populated boards. Swings for quick needle changeovers.
- Accurate surface sensing for high quality
dot and line dispensing.
- Easy set-up through prompted scripts in
the software.
- High tolerance of extreme temperatures induced
by impingement tooling.
- Light force probing for delicate surfaces.
- Small dimensions, utilizing surface mount components.
