Adjustable Screen
Mount (ASM)
The ASM is the receptacle for the stencil during printing operations. The ASM
is fully adjustable to accommodate the most popular of stencil sizes. The print
stencil is clamped into place by the ASM during the print cycle. The ASM is a
printer option replacing the C Chase.
There are two methods used for achieving correct position of the stencil within
the chase assembly:
• Screen Depth Adjuster
• Screen Change Mechanism
The screen depth adjuster is set (Distance to Image) by the operator prior to
loading the stencil. The stencil is loaded into the chase until it reaches the stop
at the end of the screen depth adjuster.
The screen change mechanism places the stencil in the correct position calcu-
lated by the software.
Screen Alignment
Module
The screen alignment module enables adjustment of the ASM 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.
