Squeegee Module The function of the squeegee module is to apply the solder paste through the
screen image onto the board in a controlled manner. Squeegee height and
downward pressure is monitored during the print stroke to optimize the print
quality. The paste knead sequence is performed by the squeegee module
utilizing the print carriage.
Screen Alignment
Module
The screen alignment module enables fine adjustment of the print screen to
achieve optimum screen to board alignment prior to the print cycle. Actuators
move the print screen in the X, Y and theta planes to nullify the misalignment
error signal from the vision system. The print screen is clamped into place
during the print cycle.
High Throughput
Conveyor Module
The high throughput conveyor module is an optional programmable width
conveyor system. The function of the HTC is to transport up to three boards
through the machine at one time and security of the board on the print station
during the print stroke.
Rail System
Module
The rail system module is a programmable width conveyor system, utilized to
transport the board through the machine and security of the board during the
print stroke. The rail system is positioned by the rising table, during the print
stroke.
