What are the characteristics of low-temperature solder paste?

Low-temperature solder paste is a type specifically used in surface mount technology.SMTThe materials. It is a viscous substance made of tiny tin particles, rosin, thixotropic agents and other materials. This solder paste has a lower melting point compared to the traditional high-temperature solder paste. When the surface mount component cannot withstand a melting point exceeding180℃When the high temperature requires a surface mount reflow process, we will use lead-free low-temperature solder paste for soldering. ThenLead-free low-temperature solder pasteWhat is its melting point? The solder paste manufacturer will explain it to everyone:

The main component of lead-free low-temperature solder paste isSn42Bi58The melting point is138℃It is the solder paste with the lowest melting point among lead-free solder pastes. Because it contains no lead and has a low melting point, it can prevent electronic components from being scorched by high temperatures during the soldering process, such as plastic and switch components, andLEDFor components like small light beads, lead-free low-temperature solder paste is quite suitable. It has good viscosity and fluidity, which can ensure high-quality welding connections while significantly reducing the stress and displacement of components.

Another feature of low-temperature solder paste is that it is easy to maintain and reproduce. Because its melting point is relatively low, it can be inSMTDuring the process, by adding some solder paste to the already soldered components, the repair and remaking of suspended and missed soldered components can be achieved. At the same time, it can also be cleaned and removed by regular removers.

Low-temperature solder paste can also play a role in environmental protection. Due to its relatively low operating temperature, it can significantly reduce the release of toxic gases in the air, lower air pollution, and meet the demands of modern environmental protection awareness.

In conclusion, low-temperature solder paste features a low melting point, good soldering performance, easy maintenance and remanufacturing, as well as environmental friendliness. With the development of modern electronic productsSMTWith the continuous demands and development of technology, the application scope of low-temperature solder paste will become increasingly wide, and it will become an indispensable part of the electronics industry.
