10.6.2 General Information
The use of flatpack ICs is gaining more and more importance in the manufacture of printed circuit boards.
These components have now reached the point where they are almost always delivered on trays (wafflepack
magazines).
The space taken up by magazine trays is however relatively high when compared with the component density.
In addition, due to their low holding capacity, the wafflepack magazines must frequently be changed and if this
has to be done by hand this necessarily involves interrupting the placement process.
But when a wafflepack changer is used there is no time lost unnecessarily in the storing and automatic chang-
ing of the wafflepack magazines. Programmed access to up to 28 freely selectable wafflepack magazines also
increases the range of available components.
NOTE
The wafflepack changer is located on the lefthand side of the SIPLACE 80 F table.
The wafflepack changer does not require the entire width of the component table. On this side of the table
10 locations remain free which can be used for the 20 x 8 mm tape module, for example.

10.6.3 Principle of the Wafflepack Changer
With the wafflepack changer on the SIPLACE 80 F it is possible to hold up to 28 wafflepack magazines and to
change these fully automatically. The trays (level) for the wafflepack magazines are numbered in sequence
from bottom to top, with the lowest number at the bottom (1 - 28).
The magazine storage unit travels vertically until the level selected lies with in the travel range of the horizon-
tal axis. The horizontal axis then removes the tray from the level and transfers it into the access area of the
placement head.
The following Fig. 10.6.2
shows the basic principle behind the wafflepack changer.

l Requirements
Flatpack magazines with the corresponding components are defined in the set-up.
After set-up conversion the magazine storage unit will make a reference run.
The PCB camera approaches the fiducials which are marked on a strip (see Fig. 10.6.3
).
