The ACJ Series applicator systems are typically used in Nordson Century
workcells to dispense solder flux on printed circuit boards and other
electronic components. This section describes the system components
and their functions, and the different applicator versions and options.
Figure 1 shows a typical ACJ system with options. A basic system
consists of an ACJ-S or ACJ-ST applicator, ACJ-1 controller, and
pressure controller. Options include a heater and co-axial air nozzle.
The applicators are electrically operated valves. The ACJ-S has an
integral flux reservoir, while the ACJ-ST is supplied from an external flux
reservoir. On a signal from the workcell dispense program, the ACJ-1
controller energizes the electromagnetic solenoid in the applicator. The
solenoid pulls the valve needle away from the valve seat, allowing flux to
flow out of the applicator nozzle. The pressure controller controls the air
pressure used to pressurize the flux supply.
