Solder pasteIt is a paste-like mixture formed by mixing solder powder, flux, and other surfactants and thixotropic agents. It is accompanied bysmtThe new type of soldering material produced by the surface mount technology is an important factor in ensuring the reliability of the reflow soldering process and is mainly applied insmtIndustrypcbIn the field of surface soldering, the following is a brief introduction to the usage methods and precautions by JJY solder Paste manufacturer:

I. Usage Method of Solder Paste

1Solder paste must be stored at2-10℃The storage period in the refrigerated space is6One month. Before use, take the original solder paste out of the refrigerator compartment. It needs to be at room temperature20-25℃Warming up4hFor the above, indicate the thawing time on the status column of the solder paste bottle, and at the same time, keep a record of the usage management form according to production needs.

2Solder paste that has not been opened for a long time must be stirred before use3-5Minutes can be taken. It can be stirred evenly by hand or with an automatic solder paste mixer before use.

3If the solder paste is found to be too dry and does not meet the production standards, an appropriate solder paste thinner can be added and stirred before use.

4When in use, take as much as needed according to production requirements. Opened but not fully used solder paste should be put back in the refrigerator. If it is improperly stored and left at room temperature for more than12hThe solder paste is scrapped.

Ii. Precautions for Using Solder Paste

1The opening time should be as short as possible. After taking out enough solder paste, the inner cover should be immediately closed.

2After taking out the solder paste, immediately close the inner cover and press it down forcefully to squeeze out all the air between the cover and the solder paste, ensuring that the inner cover is in close contact with the solder paste.

3The removed solder paste should be printed as soon as possible: The printing work should be continuous without interruption, and the removed solder paste should be put into printing and use as soon as possible.

4The handling of the excess solder paste that has been taken out: After all the printing is completed, the remaining solder paste should be recycled into a dedicated bottle as soon as possible, following the instructions2Store away from air. Do not put the remaining solder paste back into the unused solder paste bottle.

5When operators are working, they should be careful to avoid direct contact of solder paste with the skin.
