Glossary G-1

Glossary

AC: Alternating Current.

Amperes Interrupting Capacity (AIC): Also known as

“breaking capacity” or “short circuit rating”. It is the

maximum current that an Overcurrent Protection Device

can safely interrupt at rated voltage.

Area-Fill: Dispensing lines of fluid within a geometric

pattern to completely cover an area.

ASPA System: Advanced Semiconductor Package

Assembly fluid dispensing system.

Auer Boat: A carrier used to transport multiple workpieces

through the dispensing system.

Automatic Pattern Recognition System: A vision system

that finds workpiece fiducials to reliably locate dispensing

sites and compensates for minor workpiece misalignment

during dispensing.

Axis: X, Y or Z geometric dispensing coordinates. See

Figure G-1.

Figure G-1 XYZ Axis Definition

Bulkhead: Bracket attached to the Dispensing Head that

supports electrical and pneumatic connections for

Dispensing Head accessories.

Camera Offset: The calibration of the XYZ location of the

Camera with respect to the dispensing needle.

Carrier: A device such as an Auer boat or lead frame onto

which workpieces are mounted and carried during the

dispensing process.

Carrier Height: The height that the carrier holds the

workpiece above the Heater Tooling or Conveyor belt.

CE: The abbreviation of the French phrase "Conformité

Européene" which literally means "European Conformity.”

CE qualification indicates that a manufacturer's

electric/electronic equipment product complies with

European Union health, safety, and environmental

protection Product Directives (standards). CE qualification

means that the product can be legally sold and freely

transported within European Union markets.

Chip: Also called a die. A small piece of semiconducting

material (usually silicon) that contains a discrete

component or an embedded integrated circuit.

Circuit: A combination of electrical or electronic

components, interconnected to perform one or more

specific functions.

Circuit Breaker: A switch that automatically interrupts the

electrical supply to the system when the current exceeds the

set level. Some circuit breakers can be manually operated

to turn power off and on for servicing or maintenance

purposes.

Cleaning Agent: A solvent or other cleaning liquid

recommended by the dispensing fluid manufacturer’s

Material Safety Data Sheet.

Conveyor Belt: A large, motor-driven o-ring that

transports workpieces/carriers through the dispensing

chamber. There are two o-rings; one for each

Conveyor rail.

Crosshairs: Two lines intersecting at a 90 angle in the

center of the video display on the Computer Monitor. Used

to teach dispensing points to the FmNT software.

Current: The flow of electrons through an electrical

circuit. Usually measured in amperes.

DC: Direct Current.

Die: See Chip.

Dispense Station: The part of the dispensing chamber

where dispensing is actually performed.

Dispensing Calibration Module (DCM): An integrated

group of components in the dispensing chamber that

includes the Purge Station, Weigh Station, Needle Sensor,

and a ceramic substrate. The components are used in

servicing or calibration of Dispensing Valves.

Dispensing Chamber: The interior area of the dispensing

system inside the Hatch where dispensing operations are

performed.

Dispensing Head: The robotic fluid applicator that moves

during the dispensing operation. The Dispensing Valve,

Height Sensor, Camera and Lighting, and Dispense Head

Controller are mounted on the Dispensing Head.

Sometimes referred to as the Z-Head.

Dispensing Runs (Wet/Dry): A wet dispensing run is

when fluid is dispensed. A dry run is when the program is

executed but no fluid is dispensed.

Dispensing Valve: A device used to control or regulate the

flow of material from a pressurized reservoir, such as a

syringe. These devices include Valves

, Pumps, and Jets.
