What is solder paste?
1. Solder paste is a new type of solder material that comes with SMT.
2. Solder paste is a complex system consisting of solder powder, flux and other additives.
3. At room temperature, the solder paste has a certain viscosity, which can initially adhere the electronic components to the predetermined position.
4. Under the soldering temperature, through the evaporation of and some additives, the soldered components and the printed circuit board are soldered together (permanent connection).
instruct:
1. The temperature of the solder paste should be raised to ambient temperature (25°C) before opening, and the temperature recovery time is about 3-4 hours. It is forbidden to use other heaters to increase the temperature instantly.
2. After opening the solder paste, it is recommended to use it within 24 hours at room temperature.
3. When placed in the air for a long time, the solder paste will become a tin block due to moisture absorption.
4. The indoor temperature is controlled at 22-28°C, and the humidity is RH30-60% as the best working environment.
5. To wipe the wrong substrate, it is recommended to use industrial alcohol or industrial cleaner.
preservation method:
1. The solder paste should be kept at 1-10°C.
2. The solder paste should be used for 6 months.
3. Do not put the solder paste in the sun.
Precaution:
1. Use only with adequate ventilation.
2. The solder paste contains organic solvents. Avoid repeated contact with skin. If the solder paste gets on the skin, wipe it with alcohol and rinse thoroughly with water.
3. For the sake of caution, during the operation, the fumes released by the solvent should be avoided as much as possible, and the contact time of skin and mucous membrane tissues should not be too long. Avoid repeated inhalation of vapors.
4. Avoid contact with eyes.
5. Keep away from children.
