5.6 Hand Soldering

In hand soldering of the Varistors. Large temperature gradient between preheated the Varistors and the tip of soldering iron may cause electrical failures and mechanical damages such as

crackings or breakings of the devices. The soldering shall be carefully controlled and carried out so that the temperature gradient is kept minimum with following recommended conditions for hand soldering.

5.6.1 Recommended Soldering Condition 1

（1） Solder ：

0.12~0.18mm Thread solder (Sn96.5:Ag3.5) with soldering flux in the core. Rosin-based and non-activated flux is recommended. （2） Preheating

The Varistors shall be preheated so that Temperature Gradient between the devices and the tip of soldering iron is 150℃ or below. （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

※

Perform adequate test in advance as the reflow temperature profile will vary according to the conditions of the manufacturing process, and the specification of the reflow furnace. RS INDU STRY LIMITED
