Dipping plate bottom side:
1. Dipping plate
2. Cavity plate
3. Stop plates
The Auto Cavity dipping plate allows for cavity depths from 0.01mm to 0.25mm with an adjust-
ment tolerance of ±10 µm. The maximum component size that can be used on this dipping plate is
15 mm x 25 mm.
NOTICE
All existing standard dipping plates with fixed cavity depths can also be used with the
LDU2X with Auto Cavity option.
3.2.6 Dip stroke plate
1. Electromagnets
2. Permanent magnets
3. Dip stroke plate
The dipping plate is held in place on the by four permanent magnets. Two electromagnets are used
for additional fixing dip stroke plate and check whether a dipping plate is fitted. The electromagnets
detect changes in the distance between dipping plate and dip stroke plate. This will be the case
when the dipping plate gets stuck to the park plate during the downwards movement.
NOTICE
Dipping plate not available
If the dipping plate does not fit properly, the dipping plate is not recognized and "plate not
available" is displayed.
Dip stroke plate for LDU 2 X with Auto Cavity option
The dip stroke plate of the LDU 2 X with Auto Cavity option is a special design with a height adjust-
ment mechanism. A vertically movable pusher block contacts the cavity plate and controls its ver-
tical position.

3.2.7 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 lifting axis moves the dipping plate up and down:
1. Motor
2. Coupling
3. Dipping plate
4. Dip stroke plate
5. Guidance
6. Slide
7. Bearing block (base of park plate)
The maximum lift of the lifting axis is -8.5mm to +22mm (mechanical stoppers). The basic position
(determined by an inductive switch) is at -7.5mm. The squeegee is positioned at 0mm. The dip-
ping position is at +17.5mm. Squeegee and dipping position are determined by the pulse gener-
ator of the motor.

3.2.8 Leveling device
The leveling device is based on a three-point support: one bearing ball and two adjustment screws.
The front bearing block is located on the bearing ball and the front adjustment screw. The rear
bearing block is located on the rear adjustment screw.
