the Binning Control decision block. (Note that the pass condition can also be
determined with the :CALC2:LIM<n>FAIL? query via remote.)
Immediate binning — For immediate binning, the testing process stops. The
SourceMeter outputs the pass pattern via the Digital I/O port to the component
handler to perform the binning operation.
End binning — For end binning, operation drops down to Another Test Cycle?
decision block. If programmed to perform additional tests (i.e., sweep) on the DUT
package, operation loops back up to perform the next source-measure action.
After all programmed test cycles are successfully completed, the SourceMeter
outputs the pass pattern to the component handler to perform the binning opera-
tion.
If configured to test another DUT package, the operation loops back to the top of
the flowchart and waits for the start-of-test (SOT) pulse from the component han-
dler.
Fail condition
When a failure occurs, the FAIL message is displayed (and also can be read via
remote with :CALC2:LIM<n>FAIL?), and operation proceeds to the Binning Con-
trol decision block.
Immediate binning — For immediate binning, the testing process is terminated
when a failure occurs, and the fail pattern for that particular failure is sent to the
component handler to perform the binning operation. Triggering is maintained for
other instruments or components in the test system.
End binning — For end binning, the fail pattern for the first failure is stored in
memory and operation proceeds to Another Test Cycle? decision block. If pro-
grammed to perform additional tests (i.e., sweep) on the DUT package, operation
loops back up to perform the next source-measure action.
After all programmed test cycles are completed, the SourceMeter outputs the fail
pattern stored in memory on the Digital I/O port. This reflects the first failure that
occurred in the testing process for the device package. The component handler
places the DUT in the appropriate bin.
If configured to test another DUT package, operation loops back to the top of the
flowchart and waits for the start-of-test (SOT) pulse from the component handler.
Sorting mode
Sorting mode limits operation is detailed by the flowchart in Figure 12-5. A test is
only performed if it is enabled. If disabled, operation proceeds to the next test. The
following assumes the digital output of the SourceMeter is connected to a compo-
nent handler for DUT binning. (See “Binning systems,” page 12-10.)
