Please refer to www.unsemi.com.tw for current information.4/6 Soldering Recommendation The principal techniques used for the soldering of components in surface mount technology are infrared reflow and wave soldering. Pb free solder paste Repair soldering 1. Allowable time and temperature for making correction with a soldering iron: 350 ± 10℃, 3 sec. 2. Optimum solder amount when corrections are made using a soldering iron Soldering guideline 1. Our chip varistors are designed for reflow soldering only. Do not use flow soldering 2. Use non-activated flux (Cl content 0.2% max.) 3. Follow the recommended soldering conditions to avoid varistor damage. 260℃max 230℃ 180℃ 150℃ 20S max preheating 120S max cooling 60S max Chip varisor Solder pad Up to chip thickness PCB
