The operation of the storage method, temperature, stirring and other usage methods of solder paste, in order to makeSMTProduction has standardized requirements for solder paste.Solder paste manufacturerThe entire process of solder paste processing needs to be monitored. So, what are the specification requirements for solder paste? JJY would like to inform its partners:

    BecauseSolder pasteIt is easily affected by the environment such as air and humidity, so it is indispensable to monitor the specification requirements of solder paste. Under normal circumstances, its service life is 6One month.

    Solder paste taken out of cold areas should not be placed in warm areas to avoid contact with moisture in the air. It should be thawed at room temperature4After a few hours, unscrew the lid and observe. If there is no delamination, it can be used normally. If it occurs, it needs to be tested and found to be problem-free before it can be used.

    The used solder paste after unscrewing the lid is recommended to be used up within the same day. Unused solder paste should be stored separately in other cold areas. For the printed solder paste, packaging must be completed within the same day; otherwise, it needs to be cleaned thoroughlyPCBSolder paste must be reprinted before packaging.

    When printing, it is necessary to control the gas fluidity to be relatively small in order to reduce the emission of flux. The suitable temperature for packaging solder paste is between 20 and 26 degrees Celsius, and the air humidity should be moderate. When the relative humidity of the air is high, the rate at which the solder paste absorbs water vapor increases, which can easily lead to the formation of solder beads. High humidity is correctSMTThe quality also has a significant impact.

    Shenzhen JJY Industrial Technology Co., LTDIt is a company that has been engaged in the research of solder paste, solder wire, solder wire, lead-free solder paste, leaded solder paste, solder rods, leaded solder paste, etc. for more than ten yearsSolder paste and solder wire manufacturer.
