Model 6487 Reference Manual Limit Tests and Digital I/O 8-5
Binning
Even though no additional equipment is required to perform limit tests on the DUT, the
Model 6487 can be used with a component handler to perform binning operations. Based
on the outcome of a test, the component handler will place the DUT in the assigned bin.
Figure 8-4 shows a basic binning system. After all programmed testing on the DUT is
completed, the appropriate digital output pattern is sent to the component handler, which
then places the DUT in the appropriate bin. The component handler selects the next DUT
and the testing process is repeated.
