Features of PDS-105R
Substantial Saving of Resist
The use of a high-torque stepper motor as the drive source results in a consistent discharge volume, unimpeded by filter clogging or viscosity change. A repeatable accuracy (0.3%) of discharge is maintained.
• Discharge precision: ±0.3% (F.S.)
• Linearity: ±0.5% (F.S.)
• Resolution: 0.01 mL
Contamination Free
The pump portion is of tubephragm structure wetted internals are flat and smooth, with a small dead volume. Because the system hardly has a place that allows liquid resist to dwell, production of particles is prevented.
Usable for a Variety of Coating Processes
Since the discharge velocity can be changed freely in a shot, the system is capable of dealing with a variety of resist coating processes including application of a very small amount or in a very short period of time.
Reduction of Downtime
A discharge amount and a discharge time can be set only by entering values in the controller. It can save operator’s time and labor and reduce downtime.
