- Preheat the capacitor at 120 to 150℃
for 1 minute. (Preheating for 3225,
4520, 4532 Step1 : 100℃ to 120℃, 1min
Step2 : 170℃ to 200℃, 1min) Immerse the
capacitor in a eutectic solder solution
- Soldering Temp. : 260±5℃
- Immersion Time : 10±0.5sec
- Initial measurement
Perform a heat treatment at 150+0, -10℃
for one hour and then let sit for 48±4
hours at room temperature.
Perform the intial measurement.
- Measurement after test
Take it out and set it for 24±2 hours
(temperature compensating type)
or 48±4 hours (high dielectric constant
type)then measure
