Setting Up the Bin Sorting Function
7. Sorting DUTs Based on
Measurement Results
Setting the boundary between good and bad bins (OUT_OF_GOOD_BINS line)
You can classify bins as good or bad. When a DUT is sorted into a bad bin, the handler
interface output signal /OUT_OF_GOOD_BINS becomes active (Low). A bad bin is
useful, for example, when you want to eject defective DUTs into a separate location.
NOTE Also, the /OUT_OF_GOOD_BINS signal becomes active when a DUT is not sorted into
any of bins 1 through 13. For more information, refer to Table 12-2, “Mapping between
Bin Sort Results and Handler Interface Output Signals,” on page 145.
You can specify the boundary between good and bad bins (the OUT_OF_GOOD_BINS
line) with the number of the good bin that is to be adjacent to the boundary. All bin
numbers that are equal to or smaller than the specified bin number represent good bins,
while those that are larger than the specified number represent bad bins. To set the
boundary, use the following command:

Defining individual sorting conditions
When you define a sorting condition, you must specify the limit range as well as the
measurement point number and measurement parameter that correspond to the measured
values to which the limit range is applied. You can define the boundary of the limit range
by specifying the boundary value either as an absolute value (“absolute mode”) or as a
value relative to a reference value (“tolerance mode”). Tolerance mode is further divided
into two modes: “deviation tolerance mode,” where you can specify the relative boundary
value as the difference from the reference value, and “percent tolerance mode,” where you
can specify the boundary value as a percentage of the reference value. Use the commands
listed in the table below to define sorting conditions:
