OnBoard Inspection and Pattern Matching
OnBoard Inspection
The OnBoard PCB Inspec-
tion (SW option) uses the
PCB camera to inspect criti-
cal areas of the board, spec-
ified by the user, e.g. under
BGA or shields just before or
after placement, to make
sure that all components
were placed or to make sure
that there are no objects in
the way of the placement
process.
It is also possible to inspect
the solder paste to make
sure that it is present. How-
ever, this must always be
performed at the first place-
ment machine, before any
placement begins.
A requirement for all inspec-
tion tasks is that a "good pat-
tern" has been saved before
starting.
Pattern Matching
Pattern matching can be
used for components with
very fine contact pads, which
can not be detected with the
existing component camera
resolution. Searching and
detection is performed over a
larger area, which contains
unique structures (patterns).
Once the specified area has
been detected, the compo-
nent is aligned and placed
according to the position of
this area and in relation to the
substrate.
