Most solder paste requires proper refrigerated storage. By the time you receive most pastes, you don't know how long it has been stored, nor if it has been stored properly. The new Two-Part solder pastes from Chip Quik solve this problem! This new formula can be stored for at least 24 months before mixing at room temperature, and then can be stored for 6 months refrigerator after mixed. No more throwing away expensive solder paste!
