8.25 Short Tape Handling for X-Feeders
If the end of a tape has been reached on an X-feeder the cover foil breaks and an error message is
displayed. In order to pick up the remaining components from the tape or process short tapes
without cover foils, the short tape handling mode has been introduced for X-feeders.
First, the Display short tape handling solution setting has to be enabled under Settings – GUI
settings – Setup. For this, the Machine service activity level is required. The setting remains valid
after a restart.

The Activate short tape handling option will then be displayed as solution in the Cover foil
broken … error message.

By using the short tape handling mode also the very last component can be picked up from the
tape. Thereafter, the production stops after the set number of pickup failures has been reached
(Stop placement after pickup failure setting is enabled in the Software options). The mode will
be terminated if one of the following events occurs:
– A new tape of normal length has been set up on the feeder. The tensioning of the cover foil
terminates the mode.
– The feeder has been removed and re-inserted.
– The placement machine or the station software has been restarted.

8.26 SIPLACE Vision Enhancements
The SIPLACE Vision system has been enhanced as follows.
8.26.1 New Camera Interface GigE
SIPLACE Vision now also supports GigE cameras.
8.26.2 Binning Can Be Disabled
With the so called "binning" 2x2 pixels (for sensor system type 30: 4x4 pixels) are combined to one
pixel. Thus, the resolution is lower and the measure time reduced. Binning is performed
automatically for some components.
As of this station software version, binning can be disabled in the algorithm parameters on the
SIPLACE Vision GUI (value "1" = no binning). The setting is valid for the current sensor type only.
The parameter is available for all components and can be used on all placement machines.
8.26.3 Measuring Dies with Pattern Matching
Usually, the components are measured by SIPLACE Vision on the basis of their electrical
connectors which are detected by filters specially adapted to the connector geometry. However,
some dies only show internal structures for which no suitable filters exist. With "pattern matching" it
is now possible to measure such structures more accurately.
At first, the pattern used for measuring the die will be created and taught by means of a teaching
wizard. On the basis of a reference die, points get measured at which the brightness strongly
changes in the picture. These points form the pattern.
All relevant calculations are performed automatically by the system. However, if necessary, the
operator may manipulate the teaching procedure by setting parameters. I.e., parts of the
component may be excluded from the teaching procedure (while not sure enough).
During the measurement of the component the position is detected at which the picture content
best matches the taught pattern points. At low concordance the component will be rejected.
8.26.4 New Pin Types: THT Round Pin and THT Square Pin
Two new pin types have been introduced to place THT components (Through Hole Technology):
THT round pin and THT square pin. The height of the components has to be described as follows
in SIPLACE Pro:
– Height = pin length + base unit height
– A creep distance with height = pin length
Thus, an inspection with correct focussing can be performed in SIPLACE Vision.
8.26.5 Storing Vision Data
Until now, some Vision data as e.g. illumination values could be stored line- or station-specifically
without any security check.
As of this station software version, the same rules apply for such Vision data as for the other Vision
data (geometrical values). I.e., if the SIPLACE Pro security is enabled, the user must have the
corresponding authorization on the SIPLACE Pro computer.
