G-4 Glossary
SMEMA: Surface Mount Equipment Manufacturers
Association. Established protocol for signal communication
between two or more different systems.
SMA: Surface Mount Adhesive. An adhesive used for
attaching chips to PWBs.
SVGA: Super Video Graphics Array. A video card that
produces high-quality color images at high resolution.
Syringe: A reservoir containing the dispensing fluid that is
usually attached to the dispensing valve.
Tactile Sensor: A sensor located adjacent to the needle
sensor that is used to calculate the Z-axis offset between the
height sensor probe and dispensing needle tip.
TFT: Thin Film Transistor. The monitor component that
provides color images for a liquid crystal display.
Underfill: The process of flowing epoxy underneath a flip
chip on a PWB to completely seal the solder bumps.
V: Abbreviation for volt as in VAC (Volts Alternating
Current). See also AC, DC.
Valve: A Fluidmove-controlled type of dispensing valve,
such as the DV-09, that dispenses by opening and closing a
needle, spool, or pinch tube valve to start and stop the flow
of a pneumatically pressurized fluid. Fluid heating, if
required, is accomplished using a needle heater attached to
a Luer adapter. Can be configured to dispense dots, lines,
or patterns.
Viscosity: Viscosity is a measurement of the flow
properties of a fluid. High viscosity fluids have a high
resistance to flow and low viscosity fluids have a
low resistance.
Vision Card: Computer card that receives video signals
from the camera and performs fiducial image capture.
Vision System: Includes the camera, light source,
computer hardware and software, and the monitor.
Weigh Station: A location on the Axiom X-1020
Dispensing Calibration Module where a scale measures the
weight of dispensed and sends the information to the
Fluidmove software for mass flow calibration.
Workpiece: Any surface, part, or element (usually a PWB)
that is being dispensed upon. Workpieces may be installed
in a carrier such as a lead frame or Auer boat.
X-axis: Left to right movement of the dispensing head in
the dispensing chamber. See Figure G-1.
X-beam: The apparatus that spans the width of the
dispensing chamber. The dispensing head is mounted to the
X-beam and slides along it in the X-axis. Includes
mechanical pulleys for the X-axis cables.
Y-axis: Forward and backward movement of the
dispensing head in the dispensing chamber.
See Figure G-1.
Z-axis: Up and down movement of the dispensing head in
the dispensing chamber. See Figure G-1.
