1. One of the major advantages of environmentally friendly lead-free solder paste is environmental protection. Since lead-free solder paste is harmful to human body and the environment, the use of lead-free solder paste has been prohibited in western countries such as Europe and America. If the customer is from abroad, it is generally required to use lead-free solder paste, but lead-free solder paste is more expensive than lead solder paste.
2. Low temperature: we know that the reflow soldering temperature of general lead-free solder paste is higher than that with lead, but the real situation is that lead-free solder paste is divided into high temperature, medium temperature and low temperature lead-free solder paste. Among them, there are two kinds of low-temperature lead-free solder paste: 1. Tin and silver; The former 138 melting point, the latter 183 melting point, low temperature lead-free solder paste can be used for some conventional
3. Strong activation: compared with lead-free solder paste, lead-free solder paste has stronger activation, but its wettability is not as good as that of lead. As long as the temperature curve of lead-free solder paste is adjusted well during reflow soldering, the data provided by the manufacturer and supplier of lead-free solder paste are used as reference, and the process parameters are adjusted after testing, good welding effect can be obtained
