Adjustable Width
Screen Mount
(AWSM)
The AWSM is the receptacle for the stencil during printing operations. The
AWSM is fully adjustable to accommodate the most popular of stencil sizes.
The print stencil is clamped into place by the AWSM during the print cycle. The
AWSM is a printer option replacing the C Chase.
The screen change mechanism locates the stencil within the chase assembly.
Screen Alignment
Module
The screen alignment module enables adjustment of the AWSM to achieve
optimum stencil to board alignment prior to the print stroke. Actuators move the
print stencil in the X, Y and theta planes to nullify the misalignment error signal
from the vision system.

Print Carriage
Module
The print carriage module is the vehicle that transports the following:
• Squeegee/ProFlow Module
• Paste Dispenser Module
• Screen Change Module
Paste Dispenser
Module
The function of the paste dispenser module option is to apply a precise amount
of solder paste onto the print screen, the frequency is fully programmable in
software.

Pneumatics
Module
The function of the pneumatics module is to supply regulated air pressure to the
pneumatic devices throughout the printer. The air supply is routed to the
required pneumatic device via an electrically operated solenoid valve controlled
by the printer control system.
There are two banks of pneumatic solenoids, one located on the rear frame of
the printer and the other located on the print carriage.
Squeegee Module The function of the squeegee module is to apply the print material through the
stencil image onto the board in a controlled manner. Squeegee height and
downward pressure is monitored during the print stroke to optimize the print
quality.
ProFlow Module The ProFlow module is an optional self contained paste transfer unit, employed
to apply print material directly to a stencil, alleviating the need for squeegees
and the paste dispenser.
