* Recommended Temperature Profile for Reflow Soldering 

## **Recommended conditions for hand soldering:** 

1. Appropriate temperature (max.) of soldering iron tip/soldering time (max.): 280°C /10 s or 350°C / 3 s 

2. Using hot air rework station with tip that can melt the solder on both terminations at the same time is strongly recommended. Do not directly contact the chip termination with the tip of soldering iron. 

## **Storage:** 

1. The maximum ambient temperature shall not exceed 35°C . Storage temperatures higher than 35°C  could result in the deformation of packaging materials. 

2. The maximum relative humidity recommended for storage is 75%. High humidity with high temperature can accelerate the oxidation of the solder plating on the termination and reduce the solderability of the components. 

3. The products shall not be stored in areas where harmful gases containing sulfur or chlorine are present. 

4. MSL=1
