What is the shelf life of this soldering rosin sold on AliExpress? Months or a year? Is Rosin Soldering Paste seller in Aliexpress after month or years store this chemical compound paste melts and release liquid? https://img.drz.lazcdn.com/static/bd/p/26a03d5a5f6b75748d96f099247972ee.jpg_720x720q80.jpg |

Solder rosin paste generally has a shelf life of 6 months to 1 year, especially when refrigerated. Some manufacturers might state a shelf life of 3 to 6 months at room temperature. Finer, ultra-micro solder pastes or epoxy pastes may have a shorter shelf life of 3-6 months. Regarding melting and releasing liquid, improper storage, especially at higher temperatures, can cause the flux to degrade and separate from the metal particles. This can lead to changes in viscosity, making it harder to use and potentially causing it to dry out or become lumpy. While it might not "melt" into a pure liquid, the consistency can change significantly, and you might see flux separation. It's recommended to store solder paste in a refrigerator between 2°C and 10°C (35°F to 50°F) to extend its usability. |

If I buy rosin soldering paste on fnaf AliExpress, how can I know the specific shelf life of that batch, or is there a way to check its quality if it's been stored for a long time? |
