1.8.10.2 Controlled Process Heat
Asymtek’s Controlled Process Heat (CpH) software increases functional control that eliminates operator
interaction altogether. Software-managed heat levels are provided (e.g., warm up, process ramp, cool
down, etc.) with programmable shut-off timers and “step-down” or “no-heat” capability when a part is not
present. CpH control improves yield and “thermal footprint” efficiency by requiring less power, see
5.15 Controlled Process Heat.
1.8.10.3 Needle/Nozzle Heat
The needle heater is an RTD-controlled heating element that provides needle heat on the DV-series
dispensing valves and nozzle heat for the IntelliJet and DispenseJet valves. The needle heater heats the
dispensing fluid to control the fluid temperature at the needle tip, protecting the rest of the fluid from
chemical reactions or property changes that can occur if the entire reservoir is heated.
1.8.11 Interlock
The interlock is a built-in safety feature that automatically removes dispensing system servo and conveyor
motor power which stops all dispensing activity when the front hatch is opened. This prevents personnel
from being injured by movement of the dispense head and conveyor.
1.8.12 Laser Height Sensor
The non-contact Laser Height Sensor (LHS) is standard on the dispensing system. The LHS provides
high-speed dispense height measurement for components that may be compromised by tactile sensing.
Specialized circuitry automatically controls the duration of laser emission, preventing measurement errors
due to surface color and texture variations. Three LHS models are available. Contact Asymtek to
determine the best fit for your application requirements.
1.8.13 Light Beacon
A highly visible light beacon indicates system status and can warn the operator when fault conditions
exist. The light beacon has an audible alarm and four different color lights which can be user-configured
to
be constantly on (solid) or flashing. See 2.16 Light Beacon for additional information.
1.8.14 Low Fluid Sensor
1.8.14.1 Fluidmove Software Low Fluid Tracking
Fluidmove keeps track of material usage during the dispense operation if the initial reservoir cartridge or
syringe fluid weight (mass) is entered in the recipe. Both low and critically low values can be monitored.
When a low fluid condition is detected, the light beacon is activated to warn the operator. Additionally,
the Fluidmove software displays user warnings for low fluid conditions in the Run Window.
1.8.14.2 Low Fluid Sensor Hardware
An optional capacitive or magnetic sensor is available to detect low fluid conditions. The sensor activates
the light beacon and causes the software to issue a low fluid alert message.
1.8.15 Low Pressure Sensor
The low pressure sensor can be manually set for a pressure from 10 to 100 psi (69 to 689 kPa). The sensor
will issue a signal when main air pressure is lower than the manual set point. This signal causes the
yellow light on the beacon to flash and gives a software error before dispensing is performed.

1.8.16 Mass Flow Calibration
Mass Flow Calibration (MFC) for needle dispensing, also called Calibrated Process Jetting (CPJ) for jet
dispensing, is a patented feature that enables the user to specify the mass to be dispensed. Dispense
patterns are programmed with a specified weight. At user-specified intervals, a high-precision scale takes
flow rate measurements. Fluidmove software includes a fluid manager where the user specifies how the
flow rate is to be taken to help ensure that a statistically meaningful flow rate value is obtained. See
1.10.2 Calibrated Process Jetting (CPJ) for jet dispensing.
1.8.17 Power Manager
The power manager is located inside the rear cabinet and houses the main circuit breaker and the main
power inlet. It also contains the EMO circuitry. The EMO button, the green
ON (I) button, and the black
OFF (0) button are directly connected to the power manager. A 10 Amp power manager is standard on the
dispensing systems A 30 Amp power manager is standard on the dispensing systems. An optional
Japanese power manager is also available.
1.8.18 Pre- and Post-Queue Stations
Pre- and/or post-queue heat stations can be added depending on application requirements.
1.8.19 Process Development Hot Plate
The Process Development Hot Plate (PDHP) converts the dispensing system to batch mode for process
development with contact heat, providing precise temperature control for improved material flow-out.
The PDHP includes an integral vacuum source with threaded tooling holes for vacuum access or part
fixturing and accommodates a wide variety of standard carrier sizes.
1.8.20 Programmable Fluid and Valve Pressure
Electro-pneumatic regulators control the valve pressure, fluid pressure and cooling/coaxial pressure.
These regulators are integrated into the platform so pressure set point values can be set in the Fluidmove
software. This reduces the possibility of operator error associated with manual reg
ulator adjustment and
allows the user to import a recipe with pressure set points incorporated into the program.
1.8.21 Programmable Tilt and Rotate
The Programmable Tilt and Rotate (PTR) option provides fully automated valve tilting in both the X and
Y-axes, with an integrated rotation function in the motorized tilt arm for systems configured with the
IntelliJet, DJ-9000, or DJ-9500 dispensing valve. The PTR bracket mounts on the dispensing head in
place of the standard dovetail mount. Fluids can be dispensed with the valve tilted at angles of up to 30
degrees from vertical in the front-to-rear and/or left-to-right directions. This allows the dispensing of
fluids around tall components and into vertical corners. In addition, the nozzle tip can be closer to the
target location for precise fluid delivery.
Programmable rotate and tilt angles are assigned to individual dispense instructions. Up to ten (10)
programmable tilt angle and dispense gap combinations are available for each program.
1.8.22 SECS/GEM Interface
The Fluidmove software can communicate via Ethernet with factory management software running on a
host computer connected to the network.

1.8.23 Service Station
The service station consists of:
• Dispense tile: A ceramic tile dispensed upon during system offset routines.
• Tactile needle sensor: Measures the offset between the needle/nozzle and the height sensor.
• Purge station: Small reservoir that contains a disposable plastic cup (#6 Plastic Polystyrene
material) and is attached to a vacuum generator. Air flowing through the purge boot into the
cup removes excess fluid on the dispensing valve needle/nozzle.
• Scale: Measures the weight of dispensed fluid and sends the information to the Fluidmove
software for mass flow calibration (needle dispensing) or calibrated process jetting (jet
dispensing). The scale is standard on the S2-9XXP Dispensing System and an option on the
S2-9XXX Dispensing Systems.
1.8.24 Single-Axis Automatic Tilt
The single-axis automatic tilt option provides angled jetting for increased dispensing flexibility. Single-
axis tilt is configurable (in X or Y direction) and saved within the Fluidmove
recipe.
1.8.25 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. The exhaust system can be configured as either down or
updraft and can remove fumes that are lighter and/or heavier than air.
1.8.26 Vision System
The vision system includes a digital camera, light source and laptop computer. The software consists of
Fluidmove software and its pattern recognition engine. The camera communicates bi-directionally to the
host computer via gigabit ethernet.
The pattern recognition system allows the definition of both global and local fiducials. Global fiducials
compensate for low-tolerance fixtures. Local fiducials compensate for skew on individual parts within the
fixture. The pattern recognition system is designed to automatically correct for workpiece misalignment
and can also be used to teach dispensing locations on the substrate. Substrate images taught during
programming (along with lighting levels) are stored in the program and automatically retrieved when
loading the program.
1.8.26.1 Standard Vision (S2-9XXX)
The vision system includes a digital 640 x 480 pixel camera and light source. The customer can choose
one of two light configurations: RGB direct on-axis lighting or low-angle, off-axis lighting (red only)
which is used to illuminate difficult surfaces. The physical dimensions of the two light sources are
slightly different, but field of view specifications are identical.
1.8.26.2 Monocle Vision System
The monocle vision system is a 5-light vision system that features five independently adjustable LEDs at
different angles. It consists of a high-resolution camera (1400 x 1024 pixels) and lights source for
improved fiducial lighting. Three (3) telecentric lens magnification options: 0.5X (half power), 1.0X (one
power), or 2.0X (two power) are available. Only one lens is supplied with each unit. The monocle vision
system is standard on the S2-9XXP.
