Solder paste usage requirements:

1. The solder paste should be kept in the refrigerator.

2. Before using the solder paste, take the solder paste out of the refrigerator in advance, and place it in the room to naturally return to temperature. This is to restore the solder paste to the normal indoor working temperature. Please note that the cap of the solder paste bottle should not be opened during the temperature recovery process to prevent moisture in the air from condensing on the surface of the solder paste and affecting the viscosity of the solder paste and the welding effect on the product. Solder paste is best used in an ambient temperature of 22°C-24°C and a humidity of 55-65%.

3. Before using the solder paste, in order to mix the flux and tin powder evenly, please stir it fully after returning to temperature, and stir until it can flow naturally.
