QX2 system elements and functions
Power supply
The power supply unit provides airflow, vacuum, and heat, and
forms the main base unit of the system.
Heater head assembly
Integrated with the frame, the heater head
assembly allows controlled vertical
movement, and includes the heater
and the vacuum pickup.
Z-axis knob
The Z-axis knob provides fine vertical
adjustment of the heater head over
the PCB.
Theta rotation and nozzle release lever
The theta rotation and nozzle release lever allows you to adjust
the angle of the nozzle around the Z-axis, to enable the nozzle
to be exactly aligned with the component and leads. Pushing
the lever past its stop actuates the nozzle release mechanism,
allowing nozzles to be changed easily.
Nozzles
A selection of nozzles is available for the QX2 that permit a
large range of components to be reworked. Focused convec-
tion nozzles, rather than box nozzles, direct hot air only at the
leads, where it is required.

Remote controller
The controller provides the main interface between you and the
QX2. It can be moved to suit your needs
Airflow selector
The airflow selector determines the rate at
which thermal energy is transferred to the
component.
Temperature display
Displays the temperature of the heater
exhaust or the temperature measured by an
auxiliary thermocouple in either ºC or ºF.
The heater exhaust temperature is preset at
350ºC and may be reset by the process
engineer to anywhere between 250ºC and
450ºC by entering an unlock code.
Mode selector
By turning the mode selector ring, the user
selects
Remove mode
This mode activates the vacuum pickup, which
applies about 3 oz. of upward force to the
component. When component liftoff is sensed,
the heater is automatically turned off.
Attach mode
This mode reflows a new component to the
PCB. By adjusting the time stored in Remove
mode with the
appropriate reflow time, which may be adjusted
on the fly if desired.
Timer
By counting up during removal and down during
attachment, the timer removes a source of
subjective guesswork from the rework process.
Start/Stop button
Pressing the Start/Stop button initiates or ends
the remove or attach cycle. In remove mode,
stopping the cycle also shuts off the vacuum, to
release components after liftoff.
