- 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.

Founded in 1977, Yageo Corporation is a premier global provider of passive component solutions. Through strategic acquisitions of industry leaders such as Pulse Electronics, BrightKing, and KEMET, the company has built a comprehensive product portfolio and established a commanding presence across the electronics industry, particularly in capacitors, resistors, and circuit protection technologies. Our extensive range of Yageo components is heavily focused on their advanced circuit protection solutions. We carry a comprehensive selection of transient voltage suppression (TVS) devices, featuring hundreds of TVS diodes and varistors engineered to safeguard sensitive electronics from destructive voltage transients. This core offering is complemented by a robust lineup of gas discharge tubes (GDTs) designed for reliable overvoltage protection in demanding environments. Beyond voltage suppression, we supply a variety of Yageo's specialized thermistor products, including resettable fuses, inrush current limiting (ICL) NTC thermistors, and precision temperature sensing components. Rounding out our selection are high-performance Yageo RF and single-band chip antennas, providing reliable, space-efficient connectivity for modern wireless applications.
