Test Methods And Results
Test Item
Test Method
Specification
DC Spark-over
Voltage Vs(V)
Add and measure the DC Voltage gradually Maxto get the discharge threshold
voltage. The measuring current is 1mA/1 second max.
It depands on each spec.
100MΩ min.
Insulation
Resistance
Measure the insulation resistance of two end of leadwire under the specified DC
voltage.
Measure the Electrostatic Capacitance under the test condition of 1KHz,DC
6V(max).
Capacitance Cj(pF)
Life(JSE)
1pF max.
Apply a standard impulse voltage (8X20μsec)of 100A for 5 times with intervals of 30
sec., and then change the polarity of the surge and apply a impulse again. Then
measure DC spark-over voltage, IR & Capacitance.

1.High soldering temperatures and long soldering times can cause
leaching of the termination, decrease in adherence strength, and
the change of characteristic may occur.
T
2.For soldering, please refer to the soldering curves above.
However, please keep exposures to temperatures exceeding 200℃
to fewer than 50 seconds.
150~180℃
3.Please use a mild flux (containing less than 0.2wt% CI). Also, if
the flux is water soluble, be sure to wash thoroughly to remove any
residue from the underside of components that could affect
resistance.

1) Time shown in the above figures is measured from the point when chip surface reaches temperature.
2) Temperature difference in high temperature part should be within 110℃
3) After soldering, do not force cool, allow the parts to cool gradually.
Cleaning
When using ultrasonic cleaning, the board may resonate if the output power is too high. Since this vibration can cause cracking or a decrease
in the adherence of the termination, we recommend that you use the conditions below.
Frequency: 40kHz max.
Output power: 20W/liter
Cleaning time: 5 minutes max.
