- 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. 

## Hand Soldering 

Solder iron temperature: 350±5℃ 

Heating time: 3 seconds max. 

## General attention to soldering 

● High soldering temperatures and long soldering times can cause leaching of the termination, decrease in adherence strength, and the change of characteristic may occur. 

- For soldering, please refer to the soldering curves above. However, please keep exposures to temperatures exceeding 200℃ to fewer than 50 seconds. 

● 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. 

## 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.
