5.7.1 Capacitor sorting
Capacitor type: 0805CG271
Basic requirements: the capacitance is divided into two bins: BIN J and BIN K.
When the capacitance passes and the loss fails, it will be sorted additionally.
Measurement parameters: frequency of 100kHz, level of 1Vrms, SLOW, FAIL
alarm and external trigger.
Sorting parameters: J bin -4.6% ~ +4.8%, K bin -9% ~ +10%, loss tg <
0.15%.
The parameters needed to be set in this example are listed below:
Primary parameter（FUN1）
Cp
Secondary parameter（FUN2）
D
Frequency（FRQ）
100kHz
Level（LEV）
1V
Speed（SPEED）
SLOW
Switch of auxiliary bin（AUX）
ON
Tolerance Mode of primary parameter
（MODE）
%TOL (percentage tolerance mode)
Nominal value（NOMINAL）
270pF
Lower limit of BIN1（BIN1 LOW）
-4.6%
Upper limit of BIN1（BIN1 HIGH）
4.8%
Lower limit of BIN2（BIN2 LOW）
-9%
Upper limit of BIN2（BIN2 HIGH）
10%
Lower limit of secondary parameter
（2nd LOW）
0.0000
Lower limit of secondary parameter
（2nd LOW）
0.0015
Trigger mode（TRIG） EXT（external）
Alarm mode（CMP ALARM） POOR ALARM（HIGH LONG）
Instruction:
1. For small capacitance, equivalent parallel mode should be selected.
2. When any bin of the capacitance passes but loss fails, it will be archived
additionally. Now, auxiliary bin should be set as ON and it will be sorted into AUX
BIN. If the AUX BIN is set as OFF, it will be judged as FAIL when loss fails.
3. Because the given upper and lower limit is based on the percentage tolerance
of nominal value 270pF, the primary parameter should select %TOL percentage
mode.
Specific setup:
1) In MEAS DISP page, select Cp-D and set the frequency, level and speed.
2) Press SETUP key to enter into the MEAS SETUP page and change the
