Dual Lane The dual lane printer consists of two sets of transport rails, one being a print
lane and the other being a pass through lane. The printers are a dedicated build
and available as a front print or rear print printer. Dual lane is not an option that
can be fitted to a standard printer.

Rapid Transit
Conveyor (RTC)
The RTC is a programmable width, 3 stage, conveyor system which sets the rail
width and transports boards through the printer using belts and vanes. The
system can accommodate up to three boards in the printer at one time thereby
reducing the printer cycle time. RTC printers are a dedicated build, it is not an
option that can be fitted to a standard printer.

Camera System
Module
The function of the camera system is to supply a visual indication of stencil to
board alignment and board/stencil inspection data to the printer PC enclosure.
The captured information supplied to the PC enclosure enables the processor
to:
• Align the stencil to the product board
• Provide visual information for the user on the MMI monitor
The camera assembly traverses horizontally in the X and Y axis and is driven
by either:
• Rotary Servo Motors
• Linear Servo Motors
The camera carriage is also used to transport the board stop and the under-
screen cleaner.

Underscreen
Cleaner
The underscreen cleaner module automatically cleans the underside of the
stencil so reducing the build up of paste.The underscreen cleaner is driven
across the underside of the stencil by the camera carriage.
There are two types of underscreen cleaner available:
• Underscreen Cleaner
• Cyclone Underscreen Cleaner
The underscreen cleaner module provides the facility to store solvent for wet
cleaning cycles. The external solvent tank may be mounted on either side or the
rear of the printer and is secured to the printer frame.
NOTE
Type 4 Printers The external solvent tank may be mounted on either side of the
printer and is secured to the printer frame.
The vacuum filtration unit removes excess paste from the stencil and solvent/
print material fumes. There are four types of vacuum filtration units:
• VF35i Vacuum Filtration Unit
• VF30 Vacuum Filtration Unit (Type 5 printers only)
• VF25 Vacuum Filtration Unit
• VF10 Venturi Vacuum Filtration Unit
