G-4 Glossary

Pneumatic Devices: Air pressure actuated devices such

as Stop Pins and Board Pins.

Port: A hardware interface on a computer to which you

can connect a device. Any machine connection that

allows for the exchange of electrical communication

signals. An opening in a mechanical device such as the

vacuum port in a contact heater or the conveyor port on

the Coating system.

Power Manager Module: The Power Manager Module

controls both AC and DC power supplied to all system

components.

Process Engineer: A technical level position. The

Process Engineer designs and develops processes for

automated electronic packaging using production line

equipment.

Product Frame: Product frames exist within the Base

Frame. ECXP uses fixture constraint coordinates, plus

the length and width of the product, to calculate the

coordinates of the Product Frame within the Base

Frame. The Product Frame origin is the calculated Main

Pattern Edit Frame. See also Base Frame, Pattern

Frame, and Reference Frames.

Production Shutdown: When all dispensing has been

stopped under non-emergency conditions such as the

end of a shift.

Psi: Pressure measured in Pounds Per per Square Inch

(lbs/in

). English unit of pressure measurement.

PWA: Printed Wiring Assembly. The completed PWB

with electrical components installed. Also known as a

Printed Circuit Board (PCB).

PWB: Printed Wiring Board. An insulating board

containing conductive tracks for electrical circuit

connections on which chips and other electronic

components are placed.

Reference Frames: All positioning in the workcell is

done with reference to sets of position coordinates,

called Reference Frames. In ECXP, three different sets

of Reference Frames are used: Base Frame, Product

Frame, and Pattern Frame.

Regulator: Device for controlling the amount of air

pressure supplied to a pneumatic system.

Reservoir Air Pressure Switch: Three-position switch

that toggles the air supplied to Reservoir A, Reservoir

B, or neither.

Robot: Dispensing Head.

Safe Z Height: This is the height below which the tool

tip cannot go when moving from one set of coordinates

to another during operation.

Safety Interlock System: An interlock sensor detects if

the dispensing area hood is open or closed. If the

dispensing area hood is opened when a program is

running, all dispensing motion stops to protect the

operator from injury. A second interlock sensor is

located behind the spill pan to ensure an appropriate

ventilation path when the drawer is pulled out for

maintenance.

SC-105HS High Speed Film Coater: Asymtek 5-axis

circulating fluid applicator, with a 0-360° rotate

mechanism plus tilt, which applies conformal coating in

a film rather than an atomized spray.

SC-204HS High Speed Non-Circulating Film Coater:

Asymtek 4-axis non-circulating fluid applicator, with a

0-90° rotate mechanism, that applies conformal coating

in a film rather than an atomized spray.

SC-205 Non-Circulating Film Coater: Asymtek 5-axis

non-circulating fluid applicator, with a 0-360° rotate

mechanism plus tilt that applies conformal coating in a

film rather than an atomized spray.

SC-300 Swirl Coat Applicator: The SC-300 Swirl

Coat applicator offers three modes of operation - bead,

monofilament and swirl. Ideal for conformal coating

applications, the SC-300 handles a wide range of

materials, varying in viscosity from 30 to 3500 mPa-sec

(30 to 3500 centipoise). The SC-300 is designed for use

with solvent-less coatings, supporting environmentally

responsible practices. A four-position tilt option is

available to allow coating access to vertical sides of

components.

SC-400 PreciseCoat Conformal Coating Jet: A non-

contact coating applicator ideal for applying conformal

coating materials to highly selective areas. This solution

is designed for coating small substrates or substrates

with high component density, and when there are tight

tolerances between coated and uncoated areas. The

SC-400 jet reaches locations not accessible by other

applicators, using a needle design with jetting action and

fast pulse-width modulated control.

SCFM: Standard Cubic Feet per Minute. A unit of flow

of a liquid or gas.

Select Cure UV-5 Cure Module: Asymtek's Select

Cure inline UV oven with modular design, ideal for

curing topside, bottom-side or both sides of PCBs in a

mid- to high-volume production environment. Coating

materials are cured using ultra-violet light.

Select Cure UV-6 Cure Module: Asymtek's Select

Cure inline UV oven with modular design, ideal for

topside curing in a mid- to high-volume production

environment. Coating materials are cured using ultra-

violet light.

SEMI: Semiconductor Equipment and Materials

International. An organization that defines protocols for

the semiconductor industry.

Glossary G-5

Service Shutdown: When all dispensing is stopped and

the coating system is made safe so that servicing can be

performed.

Service Technician: Trained personnel responsible for

performing advanced system servicing procedures.

SMEMA: Surface Mount Equipment Manufacturers

Association. Established protocol for signal

communication between two or more different systems.

Stop Pin (SL-940E): The Stop Pin is a pneumatic

device used to stop workpieces as they are conveyed

into the system.

SVGA: Super Video Graphics Array. A video card that

produces high-quality color images at high resolution.

TFT: Thin Film Transistor. The Monitor component

that provides color images for a liquid crystal display.

Tool Offset: The tool offset is the X, Y, and Z distance

from the robot's lower tooling pin to the tool tip (the end

of the nozzle). Robot position is calculated using the

coordinates of the tooling pin plus the offset.

Tool: A tool generally consists of a coating applicator

and nozzle. It may also be a teach camera, or a laser

pointer for programming.

Tooling Rails (SL-941E): The adjustable Tooling Rails

secure the workpiece for batch system operation.

Upstream/Downstream SMEMA Sensors: Mounted

on a bracket attached to the conveyor rail, upstream and

downstream SMEMA sensors allow you to manually

load and unload workpieces onto the conveyor in the

absence of upstream or downstream systems.

UV-Cure: Curing method that uses ultra-violet light to

cure (harden) coating materials.

V: Abbreviation for volt as in VAC (Volts Alternating

Current). See also AC, DC.

Valve: See Coating Applicators.

Viscosity: Viscosity is a measurement of the flow

properties of a fluid. The ability of a fluid to resist

deformation under stress. High viscosity fluids have a

high resistance to flow, and low viscosity fluids have a

low resistance.

Water Trap: Moisture from the outside air can

condense in the pneumatic system. The Water Trap

collects this condensed moisture. The Water Trap must

be emptied when it’s full.

Workcell: Dispensing area.

Workpiece: The board or substrate (PCB, PWA, etc.) or

a carrier (pallet, auer boat, lead frame, etc.) to be

dispensed upon.

X-Axis: Left to right movement of the Dispensing Head

in the dispensing area (Workcell).

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 area (Workcell).

Z-Axis: Up and down movement of the Dispensing

Head in the dispensing area (Workcell).
