Placement Heads
TwinHead for High-Precision IC Placement
Description
This sophisticated placement
head consists of two place-
ment heads of the same type
coupled together (twin
head). Both heads work
using the Pick & Place prin-
ciple. The TwinHead is suit-
able for processing
particularly difficult or large
components. Two compo-
nents are picked up by the
placement head, optically
centered on the way to the
placement position and ro-
tated into the necessary
placement angle. The com-
ponents are then placed
gently and accurately on the
board.
The placement head can also
use the nozzles for the Pick &
Place head (used on the F5
HM) in addition to the
nozzles recently developed
for the TwinHead.
Collect &Place head nozzles
can also be used.
Checking and self-learning
functions
The TwinHead's reliability
can be further increased with
various checking and self-
learning functions.
• For example, vacuum
checks at the nozzles indi-
cate whether the compo-
nent was picked up or
correctly.
• High-resolution, digital
component vision camer-
as such as the Fine-pitch
and Flip-chip vision camer-
as (optional) identify the
smallest deviations in the
component position. The
digital vision system cor-
rects such deviations, thus
guaranteeing a correct
placement position. The
digital component camer-
as are permanently fixed
to the machine frame.
• The component package
form is also checked and
the component is not
placed if the geometric
data thus determined dif-
fers from the programmed
data.
• A force sensor measures
and monitors the specified
component placement
forces.
