Generally speaking, due to the different ingredients and processes of the solder paste used by partners, its types also vary. Among solder paste manufacturers, there are three different types of solder pastes that are commonly produced, namely low-temperature, medium-temperature and high-temperature solder pastes. What are the differences among these three kinds of solder pastes? Friends, follow Jia JinyuanSolder paste manufacturerLet's come and learn together!

    Low-temperature solder paste. Its melting point is relatively low. When the temperature of the electronic components on the surface mount is relatively high, the surface mount reflow processing technology is also required, and low-temperature solder paste is used for soldering.

    At this point, the solder paste serves to maintain the soldered components andpcbThe function of the circuit board. In the lighting and decoration industry, it is relatively popularLEDWe warmly welcome you. The composition of low-temperature solder paste is tin-bismuth alloy. Its reflow soldering temperature is between 170 and 200.

    Medium-temperature solder paste. It isSMTAmong lead-free solder pastes, the most commonly used one mainly consists of tin-silver-bismuth alloy. Its main characteristics are that it is applied in the production of rosin, with good adhesion, which can effectively prevent collapse. The residue after re-soldering is transparent and the amount is relatively small, not hinderingICTInspection.

    High-temperature solder paste. It is mainly composed of tin, silver and copper. It has a relatively high melting point, but it has good stability and is not prone to cracking during soldering. So inLEDAmong the three types of solder paste in the field, lead-free high-temperature solder paste is the best.
