Soldering with a soldering iron

The use of a soldering iron should be avoided wherever possible. If it is

unavoidable, follow the instructions set forth in Table 5. The time of soldering with an iron should be one.

Cleaning after Mounting

The following solvents are usable when cleaning the capacitors after mounting. Never use a highly active solvent.

-Halogen organic solvent (HCFC225, etc.)

-Alcoholic solvent (IPA, ethanol, etc.)

-Petroleum solvent, alkali saponifying agent, water, etc.

Circuit board cleaning must be conducted at a temperature of not higher than 50°C and for an immersion time of not longer than 30 minutes. When an ultrasonic cleaning method is used, cleaning must be conducted at a frequency of 48 kHz or lower, at an vibrator output

of 0.02 W/cm3, at a temperature of not higher than 40°C, and for a time of 5 minutes or shorter.

NOTE 1: Care must be exercised in cleaning process so that the mounted capacitor will not come into contact with any cleaned object or the like or will not get rubbed by a stiff brush or the like. If such precautions are not taken particularly when the ultrasonic cleaning method is employed, terminal breakage may occur.

NOTE 2: When performing ultrasonic cleaning under conditions other than stated above, conduct adequate advance checkout.
