CLEANING
NC-31 is a no-clean solder paste that does not require cleaning for most SMT assemblies.
For applications requiring cleaning, NC-31 can be cleaned using flux residue removers such as Inventec Disper 607 and Disper 610.
STORAGE
Solder paste should be stored between 3-8°C (37-46°F) to obtain the maximum refrigerated shelf life of six months.
Unopened solder paste stored at room temperature, 25°C (77°F) will have a one month shelf life.
Syringes and cartridges should be stored vertically in the refrigerator with the dispensing tip down.
Allow 4-8 hours for solder paste to reach an optimal operating temperature of 20-25°C (68-77°F). Keep the solder paste container sealed while warming the solder paste to operating temperature.
Never Freeze Solder Paste!
