solder paste storage
1.Paste save allowable temperature 1-10 ℃, the optimum range of 5-10℃, the shelf life of six months (counting from the date of manufacture).
2. Prior to use, the solder paste previously removed from the refrigerator at least 4 hours at room temperature, which is to return to work in order to make the paste temperature, but also to prevent moisture condensation on the surface of the solder paste
the use of the environment
