（3）Soldering Iron
Rated Power of 20w max with 3mm soldering tip in diameter.
Temperature of soldering iron tip 380℃max,3-5sec ( The required amount of solder shall be melted
in advance on the soldering tip.)
（4）Cooling
After soldering. The Varistors shall be cooled gradually at room ambient temperature.
5.6.2 Recommended Soldering Condition 2（Without preheating）
（1）Solder iron tip shall not directly touch to ceramic dielectrics.
（2）Solder iron tip shall be fully preheated before soldering while soldering iron tip to the external
electrode of Varistors.
5.7 Post Soldering Cleaning
5.7.1 Residues of corrosive soldering fluxes on the PC board after cleaning may greatly have influences on the
electrical characteristic and the reliability (such as humidity resistance)of the Varistors which have been
mounted on the board. It shall be confirmed that the characteristic and the reliability of the devices are not
affected by the applied cleaning conditions.
5.7.2. When an ultrasonic cleaning is applied to the mounted Varistors on PC Boards. Following conditions are
recommended for preventing failures or damages of the devices due to the large vibration energy and the
resonance caused by the ultrasonic waves.
（1）Frequency 29MHz max
（2）Radiated Power 20w/lithr max
（3）Period 5minuets max
