Solder the capacitor to the test jig (glass epoxy board) shown in
Fig. 1a using an eutectic solder. Then apply 10N*force in
parallel with the test jig for 10
T1 sec.
The soldering should be done either with an iron or using the
reflow method and should be conducted with care so that the
soldering is uniform and free of defects such as heat shock.

(2) High Dielectric Constant Type
The ranges of capacitance change compared with the 20
D
value over the temperature ranges shown in the table should
be within the specified ranges.
*
In case of applying voltage, the capacitance change should be
measured after 1 more min. with applying voltage in
equilibration of each temp. stage.
The capacitance change should be measured after 5min. at
each specified temp. stage.
(1)Temperature Compensating Type
The temperature coefficient is determind using the capacitance
measured in step 3 as a reference.
When cycling the temperature sequentially from step 1 through
5 (5C :
W25D to W125D/?C : W20D to W125D : other temp.
coeffs. :
W25D to W85D/W20D to W85D) the capacitance
should be within the specified tolerance for the temperature
coefficient and capacitance change as Table A-1.
The capacitance drift is caluculated by dividing the differences
between the maximum and minimum measured values in the
step 1, 3 and 5 by the cap. value in step 3.
