GUI Graphical User Interface. An enhanced DEK interface utilized in the 2D inspection, portraying a
realistic representation of a board being inspected.
Host Comms Host Comms provides the user with access to certain networking functions without accessing the
printer maintenance function.
HPR Heavy Pallet Rails. A transport system used to carry pallets up to 15kg in weight
HTC High Throughput Conveyor. A combined manual/programmable width conveyor system which
sets the rail width and transports boards through the printer using belts.
Instinctiv The DEK printer software interface providing to the user an enhanced graphically printer display.
Knead Action of working the solder paste into a soft mixture.
Loom Wiring harness or cable assembly. A loom is composed of several wires fitted with a connector.
Magna-Print Quick fit/release squeegee system. The system addresses the issues associated with maintaining
multiple squeegee blades.
MIU Machine Interface Unit. Allows the printer to communicate with other printers up and down the
line.
MMI Man Machine Interface. A modular system enabling communication between the user and the
printer, utilizing the monitor, keyboard, tricoloured beacon and the two button control system.
MTR Modular Transport Rails. Transport rails designed to accept a variety of tooling and clamping
arrangements.
