Figure 12: Theta Adjust
The lower heater head can be rotated by turning the
Theta Adjust knob. This rotates the nozzle and the
vacuum pick-up, so the component and/or nozzle can be
aligned to the PCB in the Theta, or rotational, direction.
The Theta adjust is a precision assembly with limited
travel in either direction. Take care not to continue to
turn the knob once the Theta has been adjusted to the
end of travel to avoid damaging the assembly. (Also
