* The word ‘stencil’ is used exclusively throughout this manual to describe a
stencil or screen.
Parameter Variable quantity which once set becomes the datum for other mathematical functions.
Paste Roll Height
Monitor
A system which measures the paste roll. The user can program the print cycle to apply more paste
exactly when it is needed most.
Plenum The Plenum is an extruded piece of metal forming the vacuum chamber on the under screen
cleaner.The fabric traverses over the plenum and is lifted to contact the screen when cleaning.
Power Monitor A separate program from the DEK software used as a diagnostic tool for monitoring the voltages
before and after the circuit breakers in the power supply module.
ProFlow Provides enclosed head print medium management. Three models are available - Classic, &
ProFlow ATx: across the range they print a variety of material viscosities.
Print Medium The material used to print/transfer onto a board, wafer or substrate - Pastes/Adhesives/Enzymes/
Inks.
QC Calc External computer program that provides statistical analysis of certain printer functions.
ROI Region of Interest. An area representing the current 2D inspection site superimposed on both the
stencil and board images within the vision data window.
SCAR Software Controlled Air Regulator. A software controlled regulator used to control various ProFlow
pressure settings.
Schematic Representational diagram of a system.
Screen* An emulsion coated mesh of various thicknesses, stretched onto a frame with an image photo-
graphically processed into the emulsion, through which solder paste or other media can be
deposited in a controlled fashion onto a board or other surface. (see also Stencil)
SMEMA Surface Mount Equipment Manufacturer Association. A standard type of FMI protocol.
SMPSU Switched Mode Power Supply Unit, situated in the printer power supply module. Produces various
dc voltages for the printer.
SPC Statistical Process Control. Collection of outputs from the printer used by QC Calc program.
Squeegee Device, usually rubber or metal used to distribute printable material across and through the stencil
during the print cycle.
Stencil* A shim, usually metal that has an appropriate image cut through it. The shim is secured to a metal
frame through which solder paste or such media, can be deposited in a controlled fashion onto a
board or other such surface.
Stinger Adhesive dot deposition system
TCM Temperature Control Module. An external device that connects to the DEK printer controlling the
temperature within the printer.
TRS Topside Reference System. Allows multiple substrates to be printed accurately in a single print
cycle.
Upline A term referring to an item or piece of equipment within a production line situated above the DEK
printer moving against the direction of the line towards the beginning of the line.
USB Universal Serial Bus. The USB is a 2 wire data link designed for 2 way communications between
the printer PC and the following: M36 printer controller; M37 power supply; 4 port USB hub.
USC Under Screen Cleaner. A programmable module for cleaning the underside of a screen/stencil.

CHAPTER 2 SAFETY FEATURES
OVERVIEW
The printer incorporates various safety features that provide a safe operating
environment for the operators/maintainers using:
• Safety interlocks ensure that potentially hazardous machine operations
can only be performed when the machine is in a safe condition
• Safety labels to inform the user of areas where danger or residual danger
may exist
All safety circuits have been designed to meet the safety requirements as
outlined in the machines’ CE Declaration of Conformity. The circuits check for
welded contacts before resetting. Additional safety is achieved by duplication of
the power contactors to provide redundancy.
Mains Supply Where incoming hazardous supply voltages are present, protection is afforded
by controlling access to the enclosures that house the supply. The enclosures
require tools to gain access to the inside and must only be opened by suitably
qualified personnel.
The mains isolator switch disconnects the facility mains supply to the power
supply enclosure. Mains supply still exists in the printer, up to the mains isolator
switch.
Hazard warning labels are placed on the outside of enclosures where danger-
ous voltage (100V-240V a.c 50-60Hz) terminations are present within.
Safety Notices Safety notices in the form of PROHIBITION, WARNING, CAUTION and MAN-
DATORY labels are placed on the printing printer and notices are posted
throughout the associated documentation to alert the operator/maintainer to
possible hazards which may cause physical injury or equipment damage.
The following label illustrated below, may be fitted to the printer, this signifies
that the user should refer to the relevant section of the Technical Reference
Manual before attempting to carry out work on the equipment.
