JJY | What is lead-free low-temperature solder paste?

As we all know, there are many types of solder paste. The ones that people are most familiar with might be leaded solder paste and lead-free solder paste. In fact, this is just a major category and can be further subdivided. Such as lead-free high-temperature solder paste, lead-free medium-temperature solder paste, lead-free low-temperature solder paste, etc. Today, the solder paste manufacturer will focus on explaining to everyone what lead-free low-temperature solder paste is?

The main components of lead-free low-temperature solder paste are:Sn42Bi58Its melting point is:138Degree. Lead-free low-temperature solder paste is designed for the present daySMTA kind of no-clean solder paste produced by the manufacturing process, it is refined from spherical tin powder with a special alloy composition and very low oxide content.

Lead-free low-temperature solder paste features outstanding continuous printing performance. The flux it contains adopts a low-ionic activator system with high reliability, resulting in minimal residue after reflow soldering and a relatively high insulation resistance, thus offering extremely high reliability. 

Then in what circumstances is it neededLead-free low-temperature solder paste??When the surface mount components cannot withstand it200℃When the temperature is above and the surface mount reflow process is required, low-temperature solder paste should be used for the soldering process. High-temperature reflow soldering components andPCBIt has played a protective roleLEDThe industry is very popular at presentLEDThe best welding materials in the industry. The above information is the relevant knowledge about lead-free low-temperature solder paste. JJY has been dedicated to the research and development and production of solder paste for twelve years, including lead-free solder paste, lead-free high-temperature solder paste, medium-temperature solder paste, low-temperature solder paste and leaded solder paste.
