3.2.2 Squeegee
1. Downholder
2. Cover
3. Flux tank
The removable cover of the flux tank reduces any vaporization or drying out of the flux. The down-
holder holds the flux tank in the correct position. By pressing on the downholder the flux tank can
easily be removed.
The flux tanks available so far are still compatible with the LDU:
●
Standard tank [03060794-xx]
●
Small tank [03062326-xx]
3.2.3 Park plate and drip tray
1. Park plate
2. Drip tray
The park plate is held in place by permanent magnets. The shape of the drip tray is asymmetric so
that it cannot be fitted wrongly. Two sensors on the base determine whether a park plate or a drip
tray is fitted.

3.2.5 Dip stroke plate
1. Electromagnets
2. Permanent magnets
3. Dip stroke plate
The dip plate is held in place on the dip stroke plate by four permanent magnets. Two electromag-
nets are used for additional fixing and check whether a dip plate is fitted. The electromagnets de-
tect changes in the distance between dip plate and lift unit. This will be the case when the dip plate
gets stuck to the park plate during the downwards movement.
3.2.6 Axes
The LDU has two drive axes.
The squeegee axis moves the squeegee forwards and backwards.
1. Squeegee
2. Front bearing block
3. Spindle
4. Guide rail
5. Rear bearing block
6. Coupling
7. Motor
The lift axis moves the dip plate up and down:
1. Motor
2. Coupling
3. Dip plate
4. Dip stroke plate
5. Guidance
6. Slide
7. Bearing block (base of park plate)
The maximum lift of the lift axis is -8.5mm to +22mm (mechanical stoppers). The basic position
(determined by an inductive switch) is at -7.5mm. The squeegee is positioned at 0mm. The dip
position is at +17.5mm. Squeegee and dip position are determined by the pulse generator of the
motor.
