1.7.11.2 Programmable Fluid and Valve Pressure
Electro pneumatic regulators control the valve pressure, fluid pressure and cooling/coaxial pressure.
These regulators have been integrated into the platform such that all the pressure setpoint values are set
through Fluidmove (as opposed to manual regulators). This reduces possibility of operator error when
setting the regulators manually. It also allows the user to import a recipe that includes all the pressure set
points.

1.7.12 Safety Features

1.7.12.1 Emergency Machine Off (EMO)
The S-920 Series Dispensing System features two EMO buttons that the operator or service technician
can use to immediately stop all dispensing operations in case of emergency. This feature helps prevent
injury to personnel and damage to the dispensing system and workpieces.
1.7.12.2 Interlock
The Interlock is a built-in safety feature that automatically removes dispensing system servo motor
power, stopping all dispensing activity, when the hood is opened. This prevents personnel from being
injured by movement of the Dispensing Head and Conveyor.

1.7.13 Service Station

The Service Station consists of a needle vacuum purge cup, on-board high precision scale, and a needle
calibration substrate. The Vision Assisted Prompted Setup routine enables the user to teach the service
station locations for fast and easy system setup. Refer to the Fluidmove User Guide or Online Help for
information on Vision Assisted Prompted Setup.

1.7.14 System Light

The dispensing system features a light that illuminates the dispensing area when the system is on.

1.7.15 Ventilation Exhaust System

The Ventilation Exhaust System works in conjunction with the facility exhaust system to remove excess
heat, fumes, or odors into an exhaust vent, not into the room. The system can be configured as either
down or updraft and can remove fumes – lighter and/or heavier than air. It baffles direct vapor and mist to
a spill pan and is exhausted through a plenum.

Optional Equipment

1.8.1

CAD Import

CAD Import is an optional software utility used for surface mount adhesive or solder paste applications. It
enables the user to import ASCII CAD data for automated program generation. CAD Import comes
complete with a JEDEC component library.
1.8.2

Laser Height Sensor

The non-contact Laser Height Sensor provides high-speed dispense height measurement for delicate
substrates, hybrids, and integrated circuits that may be compromised by tactile sensing. Refer to
Radiation for important safety information regarding the Laser Height Sensor.
