1-6 Introduction
1.10.4 Cleanroom
All standard S2-900 Series Dispensing System configurations meet ISO Class 6 Cleanroom specifications
with the exhaust vent on.
The scalable S2-9XXC Cleanroom configuration is specifically designed for ISO Class 5 environments
and for applications that are sensitive to contamination by submicron-sized particles, such as wafer-level
packaging. The S2-9XXC Cleanroom system is equipped with a stainless steel enclosure. Its high-flex
electrical cables are enclosed in a cleanroom-certified jacket that reduces particulation and outgassing.
The Ultra Low Particulate Air (ULPA) filter provides a downward particle-free air column within the
dispense area. All pneumatic valves are exhausted to the bottom of the machine. House vacuum is also
required for valve purge and to hold workpieces to the tooling.
1.10.5 Computer and Software
The system is equipped with a laptop computer with a Windows operating system and Fluidmove 6.0 or
higher dispensing software.
1.10.6 Conveyor
The conveyor uses multi-move technology which allows parts to move concurrently. Simultaneous
movement significantly decreases convey time, contributing to increased throughput. In one sequence, a
part is transported from the upstream machine while the S2-900 system unloads a part from the dispense
station to the downstream machine.
1.10.7 Dispensing Valves
The S2-900 Series Dispensing Systems support the following Nordson ASYMTEK jets and valves:
• DJ-9500 Series DispenseJet
®
• DV-02 Pinch Tube Valve
®
• DV-03 High-Pressure Valve with Suckback
®
• DV-05 Diaphragm Valve with Suckback
• DV-07 Adjustable Liquid Valve
• DV-01 Syringe Dispensing Valve
Refer to the appropriate dispensing valve manual for additional information.
1.10.8 Dual-Action Dispensing
Dual-action enables dispensing of two fluids with two jets, two valves, or a jet and a valve. The two
applicators operate independently. Dual-action dispensing is ideal for applications that require two
different materials dispensed on the same part, and for high-mix production when several product types
are manufactured during the same shift.
