【 JJY 】 Analysis of the Advantages and Disadvantages of Low-Temperature Lead-free Solder Paste

NowstmSolder paste is used in all industries. Different electronics require different types of solder paste. Currently, the one that is widely used isLow-temperature solder pasteSo, what is low-temperature solder paste? Melting point138℃The solder paste is called low-temperature solder paste when the surface mount components cannot withstand it138℃When the temperature is above and the surface mount reflow process is required, using low-temperature solder paste for the soldering process serves to protect the components that cannot withstand high-temperature reflow solderingPCBVery much.LEDIt is welcomed by the industry. Its alloy composition is tin-bismuth alloy. Now, the solder paste manufacturer will take you to understand the characteristics, advantages and disadvantages of low-temperature solder paste:

The advantage of low-temperature solder paste is its relatively low melting point, usually138℃. This means that during the soldering process, the soldering temperature is lower, which can avoid overheating and burning the circuit board components. In addition, using low-temperature solder paste enables circuit board manufacturers to be more flexible in layout and size characteristics to meet customer needs.

Another advantage of low-temperature solder paste is that it leaves less residue during soldering, which helps reduce the risks of solder joint degradation, circuit failure and high repair costs. Compared with traditional lead-tin solders, low-temperature solder paste is more environmentally friendly and does not produce toxic and harmful lead content.

However, low-temperature solder paste also has disadvantages. Due to its low melting point and susceptibility to heat, special caution is needed during the welding process to avoid problems such as loose solder joints and poor fluidity caused by excessive heating. In addition, the solder joint strength of low-temperature solder paste is relatively low. In some high-demand application scenarios, it may be necessary to evaluate the use of appropriate high-temperature solder paste.

With the continuous update and iteration of technology, the improvement of low-temperature solder paste in the future will further enhance its advantages and unique performance, facilitating the research and development and manufacturing of electronic devices. These are some relevant contents summarized by the solder paste manufacturer regarding the advantages and disadvantages of low-temperature solder paste.
