Maximum Quality in Production
Maximum quality in pro-
duction
The SIPLACE X-series not
only provides market-leading
machine quality; it also guar-
antees maximum product
quality through a combina-
tion of the following features:
100% placement process
control
The SIPLACE X-series has
various control mechanisms
as standard that guarantee
maximum placement reliabil-
ity. For example, sensors
check whether the compo-
nent was picked up or set
down correctly. Force sen-
sors also check the specified
component set-down forces
and compensate for differ-
ences in height during pick-
up and any bumps on the
PCB during placement.
Digital vision inspection
The digital vision system
guarantees extremely fast
and reliable component rec-
ognition, while being very
simple to use. The system
identifies each individual
component from its shape
and color. Using different illu-
mination and brightness lev-
els, almost every package
form can be easily detected.
The system also stores
images of the components,
known as “vision dumps”.
These show which compo-
nents were rejected. As a
result, errors can be detected
earlier when introducing new
products, thus increasing
process reliability. The vision
dumps also provide good
negotiation tools if defective
components are supplied.
Intelligent software for set-
up verification
The SIPLACE X series set-
ups are verified on the PCB,
on the component roll and by
the intelligent SIPLACE X
feeder modules with refer-
ence to the barcode. This
helps to avoid set-up errors.
This network of tests consid-
erably lowers dpm rates and
increases the first pass yield.
