Description
The SIPLACE bulk case
feeder module processes
bulk cases on two tracks. It
feeds rectangular and round,
passive components. The
PCB magazines (bulk cases)
are simply replaced for refill-
ing - without stopping the ma-
chine.
The module essentially con-
sists of the basic element
plus two feeder rails and
PCB magazines to suit the
component type and height.
The components are sepa-
rated and fed along the rails
by compressed air.
The principle of the fixed
component table has proven
its worth, even when bulk
cases are used: the vibra-
tions that can occur with oth-
er placement machine
concepts can have a highly
detrimental effect on the
component quality due to
abrasion, for example.
Even with stick magazines,
the stationary component
supply has significant
advantages: the universal vi-
bratory stick feeder can be
topped up during placement.

Digital Vision System
The digital SIPLACE vision
system guarantees
extremely fast and reliable
component recognition,
while being very simple to
use. The system identifies
each individual component
from its shape and color.
Even complex component
shapes, such as flip-chip or
CCGA are detected
extremely reliably.
The system is not only used
in the placement head cam-
eras; it can also be found in
the PCB camera. As well as
ensuring that components
are detected accurately, it
also ensures reliable recog-
nition of the ink spots and
PCB fiducials.
The benefits at a glance:
• Extremely fast and reliable
component recognition
• Shortest cycle times
• Robust measurement with
reference to the shape
and color
• Straightforward program-
ming
• Offline programming of
component shapes
• Rapid introduction of new
products (NPI)
• Open architecture allows
you to quickly adapt to
new requirements
• Optimum placement
results through individual
measurement of each
component

Checking the Component Quality
Flipped components Upright components
Poor component quality
Vision Teach menu at the station
SIPLACE vision algorithms
help with the detection of
• flipped components
• upright components
• poor component quality
The digital SIPLACE vision
system automatically saves
the last 500 images of com-
ponents that were identified
as "bad". SIPLACE users
can then easily demonstrate
poor component quality.
The benefits at a glance:
• Maximum placement
quality
• High first pass yield
• Reduced operating costs
