The lifting axes are moved vertically on linear carriages which are driven by a servo motor with a
spindle. The gradient of 20 degrees from the vertical axis reduces the travel path of the WTCs to
the pick-up position of the SIPLACE station.
The WTCs are also moved horizontally on linear carriages which are driven by a servo motor with
a belt drive. A driver locks into the side of the WTC and moves it out of the cassette into the pick-
up position. After the SIPLACE station has picked up the necessary components out of the waffle
pack tray, the WTC is moved back into the cassette again.
The WTCs are transferred between the lifting axis and the feed axis via defined transfer and re-
moval positions. Safety queries from the software ensure that the cassettes and WTCs are always
in the correct location when the lifting axis and feed axis are moved.
Both towers can be set up independently of each other. While one tower is being refilled, the sec-
ond can continue to supply the SIPLACE station with components. This prevents interruptions to
the placement process. Special waffle pack trays are an exception here, since they can only be
set up in one of the towers.
The MTC 2 can be docked to the SIPLACE station instead of a component cart. A separate dock-
ing frame accepts the MTC 2 and fixes it in place with two alignment pins. The exact position is
measured by two camera fiducials during the SIPLACE station reference run. The MTC 2 can be
moved on its own wheels when it is exchanged.
The system is adapted to the different standard heights (Europa and SMEMA) during the initial
setup phase, but can still be changed later without additional tools being required. The height is
adjusted with a crank mechanism when the machine is docked onto the SIPLACE station.

11.1.3 Occupying and numbering the tower
It is possible to set up and fully automatically change up to 100 JEDEC waffle pack trays in WTCs
with the MTC 2 on the SIPLACE station. The levels for the waffle pack trays are numbered for
each tower, from the bottom to the top (1-30 for tower 1 and 1-40 for tower 2). Only every second
or third level is occupied if higher waffle pack trays are used (high JEDEC waffle pack trays or
special waffle pack trays).
Fig. 11.1 - 3 Numbering of the levels in tower 1 and tower 2
The lifting axis on tower 1 can accommodate 5 cassettes with up to 6 WTC XLs each. Either two
JEDEC waffle pack trays or any number of special waffle pack trays can be accommodated in a
WTC XL.
The lifting axis on tower 2 can accommodate 4 cassettes with up to 10 WTCs each. A single JE-
DEC waffle pack tray can be accommodated in a WTC.
