The decision as to whether work will be performed with the PCB camera with normal illumination
(see User Manual, PCB Vision System) or with the optional oblique illumination (see Section 2.6)
depends on the design of the fiducials placed on the substrate.

If the optional PCB camera multicolor has been installed in place of the PCB camera with normal
illumination, it can be used to acquire at least the entire range of fiducials currently recognized
with normal or oblique illumination (see single document "User Manual PCB Camera Multicolor"
Item no. 00192790-01).

The optional "Mechanical ceramic substrate centering HS-50" is used to lock in X-direction of the
placement position, substrates with a width of 50 mm to 140 mm, with positional stability and care-
fully to protect the material. The ability to place the ceramic substrates all the way to the edge of
the substrate is a further advantage.
The mechanical ceramic substrate centering unit for the HS-50 is mounted in processing areas,
gantry 1 and 2 and/or 3 and 4 - next to the stationary side of the conveyor - on the pertinent lifting
table plate (see Fig. 2.3 - 1). Both processing areas of the pertinent conveyor have to be changed
over from PCB clamping to mechanical ceramic substrate centering (see Fig. 2.3 - 3).
If requested by a customer, the mechanical ceramic substrate centering unit can also be supplied
for "conveyor left".

The building block of the mechanical substrate centering unit is adapted to the substrate size to
be placed - 50 mm to 140 mm - by installing the pertinent stop rail and the pertinent stop unit (kit
1, 2 or 3, Item no.: see table, Fig. 2.3 - 4). This adapting is described in Section 2.3.4.

Substrate sizes that can be cen-
tered, following pertinent setup of
the mechanical substrate centering
unit:
50 mm to 140 mm
Substrate thickness: Depends on the thickness of the PCBs
Substrate design: Without scratch: troublefree within the specified dimen-
sions
Scratched: After customer test, before starting the
placement
Width of contact in the conveyor: 2.5 mm
Y-centering when using the
mechanical ceramic substrate cen-
tering unit:
Positional accuracy in accordance with the tolerance of
the set conveyor width relative to the width of the sub-
strate.
No Y-centering by the mech. substrate centering unit.
Compressed air connection: Operating pressure 5.6 bar, compressed air branch
stopper
Clearance under the substrate
when using the mech. substrate
centering unit:
12 mm
Position recognition via PCB vision,
optional oblique illumination or PCB
camera multicolor.
When ceramic substrates are cen-
tered mechanically, recognition of
the position of the fiducials is
required.
There have to be at least 2 suitable fiducials on the
ceramic substrate.
The position recognition is selected on the basis of the
surface of the fiducials, as described in the appropriate
section:
- PCB vision: See User Manual
- optional oblique illumination:Section 2.6
- PCB camera multicolor: see single document "User
Manual PCB camera Multicolor", Item no. 00192790-01
