How to see the temperature on the external label of solder paste?

Generally, the external label of solder paste has no temperature label, but it can be judged by the alloy composition inside, but some manufacturers don't like to label the alloy composition, so it is basically impossible to judge. Therefore, it is generally necessary for the manufacturer to provide you with alloy composition, so as to judge the melting point temperature or furnace temperature curve accordingly.

If you need more information in this field, please contact Suzhou Duma Technology (a school-run enterprise of Changzhou University) to provide more information consultation for free.

See the picture below. The second line writes solder paste, alloy composition 305, and it can be judged that the melting point temperature is 2 17 degrees; But many manufacturers can't judge without such a clear mark.
