【 JJY 】 Characteristics and Storage Methods of Lead-free Low-temperature Solder paste

Lead-free low-temperature solder pasteIt has been widely applied in the electronic production industry. If the surface mount component cannot withstand it200℃For the above temperatures, if a surface mount reflow process is required, lead-free low-temperature solder paste should be used. Lead-free low-temperature solder paste is generally made of lead-free tin-bismuth alloy spherical solder powder with low oxidation degree, which has excellent environmental protection characteristics. At the same time, the paste is refined from imported chemical materials, which can achieve very high stability and effect. JJY solder paste manufacturer will introduce the characteristics of JJY lead-free low-temperature solder paste:

1It has good demolding performance during printing, excellent dry resistance and good thixotropic performance, and is suitable for the mounting of most devices.

2It leaves little residue after welding, has low corrosiveness, and features an extremely high surface insulation resistance value, achieving excellent performance without the need for cleaningICTTest performance.

3When printing continuously, the viscosity change is small, which can ensure the stability of the printing effect during long-term operation.

4This product has excellent thixotropic performance. After printing, its shape remains intact and it is not prone to collapse, thus avoiding the displacement of surface mount components.

5The weld points are bright after welding and have excellent electrical conductivity.

6Fewer solder beads are produced during welding, reducing the occurrence of short circuits.

Storage method of lead-free low-temperature solder paste

1When the new solder paste is unopened, please store it2～10℃Store in the refrigerator. The storage period is6One month.

2The remaining solder paste after opening must be sealed and stored in the refrigerator. The excess solder paste scraped back from the wire mesh and the drain plate should not be mixed with unused new solder paste. It should be stored in a separate container to avoid affecting the use of the new solder paste.
