12-Nozzle Collect & Place Head for
High-Speed Placement
Description
The 12-nozzle Collect & Place
head works on the Collect &
Place principle. This means
that, within each cycle,
twelve components are
picked up by the placement
head, are optically centered
on the way to the board and
are rotated into the required
placement angle. Lastly, the
air kiss sets down the compo-
nent gently and accurately
on the board.
Checking and self-learning
functions
The reliability of the Collect &
Place head is increased by
various checking and self-
learning functions.
• For example, vacuum
checks at the nozzles indi-
cate whether the compo-
nent was picked up or set
down correctly.
•A digital component cam-
era on the placement head
determines the precise
position of each compo-
nent at the nozzle. Any de-
viations from the required
pick-up position are cor-
rected before placement
takes place.
• The package form is also
checked and the compo-
nent is not placed if the
geometric data thus deter-
mined differs from the
programmed data.
The vertical axis for picking
up and placing the compo-
nent works in sensor stop
mode, in which differences
in height during pick-up and
any unevenness of the PCB
surface are compensated
during placement.
In addition to the vacuum
check, an optional compo-
nent sensor may be used to
check for the presence of a
component at the nozzle.
The use of a component sen-
sor is recommended, particu-
larly when placing small
components, such as 0201.
"High-resolution camera“
option
The high-resolution compo-
nent camera allows the
12-nozzle Collect & Place
head to optically center and
place component sizes rang-
ing from 0201 to 18.7 x
18.7 mm².

6-Nozzle Collect&Place Head
for High-Speed IC Placement
Description
The 6-nozzle Collect & Place
head also works on the Col-
lect & Place principle. The
high-resolution digital com-
ponent camera allows the
6-nozzle Collect & Place head
to optically center and place
component sizes ranging
from 0201 to 27 x 27 mm².
Checking and self-learning
functions
The checking and self-learn-
ing functions described on
page 12 for the 12-nozzle
Collect & Place head also
apply to the 6-nozzle Collect
& Place head.
