4.1.2 Power Supply Module
The power supply module fulfils the following functions:
●
Transform and rectify the mains voltage supply to the voltages required by the electrical sys-
tems throughout the machine.
●
Electrical safety - achieved by the use of emergency stop safety circuits (E Stop button and
cover safety switches). When an E Stop is activated, power is removed from selected areas of
the machine.

4.1.4.1 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 downward pressure is monitored during the print
stroke to optimize the print quality.
4.1.4.2 Stencil Load Mechanism
The stencil load mechanism automatically loads the stencil to the correct position in the chase.
