Low-temperature solder pasteIt is a kind specifically used for surface mount technology.SMTThe materials. It is a viscous substance made of tiny tin particles, organic acids and colloidal materials. This kind of solder paste has a lower melting point compared with the traditional high-temperature solder paste. When the surface mount component cannot withstand more than180℃At such high temperatures, we will use lead-free low-temperature solder paste for soldering. So, what is the melting point of lead-free low-temperature solder paste? Now, let's have Shenzhen JJY Solder Paste Manufacturer explain it
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 to meet the requirements of modern electronic productsSMTDeveloped in accordance with the requirements of the process, it is mainly applied to quadrant array chips.QFP), thin and small pin-less packageBGAIt is used in processes such as wave welding. It has good viscosity and fluidity, which can ensure high-quality welding connections and significantly reduce the stress and displacement of components at the same time.
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. In addition, it can also be treated with conventional flux 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 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.
