parameters and one of secondary parameters. The tested result can be divided
into up to 10 bins (BIN 1 to BIN 9 and BIN OUT). If the primary parameter of DUT
is within the limit range from BIN1 to BIN9, but the secondary parameter is out of
the limit range, in this case the DUT will be sorted into aux bin. When TX6000
installs the HANDLER interface and it is used in automatic sorting system, the
compare function will be especially useful. The following limit parameter of
compare function only be set on <LIMIT TABLE SETUP> page.
Test parameter (PARAM)
Limit mode of compare function (MODE)
Nominal value (NOM)
Auxiliary bin ON/OFF (AUX)
Compare function ON/OFF (COMP)
Low limit of each bin (LOW)
High limit of each bin (HIGH)
3.7.1
Swap parameter
The swap parameter function can swap the primary and the secondary parameter
in PARAM. For example, when the test parameter is Cp-D, the swap parameter
function can change the test parameter as D-Cp. Then user can set 9 pairs of
compare limits for D, but only 1 pair of compare limit can be set for Cp.
Operation steps for the swap parameter function
Execute the following operations to swap the primary and the secondary
parameters.
1)
Move the cursor to PARAM, the following soft key will be displayed.
SWAP PARAM
2)
Press SWAP PARAM to swap the primary and the secondary parameters.
3)
Press SWAP PARAM to swap the primary and the secondary parameter,
which is to recover the formal setup.
3.7.2
Limit modes of compare function
Compare functions has two limit setup modes for primary parameters as shown in
figure 3-3.
Tolerance mode
Under tolerance mode, set the deviation value of the nominal one (be set in the
NOM zone) as the compare limit value. Deviation value has two modes:
percentage deviation and absolute deviation.
Sequential mode
Under sequential mode, the range of the test value is the compare limit value.
The compare limit value should be set in the order from small to large.
