What are the characteristics of lead-free low-temperature solder paste for smt?

inLead-free solder pasteAmong the product models,138℃The melting point of it is called low-temperature solder paste, and it is a kind of solder paste suitable for138℃At or above temperatures and with the use of low-temperature solder paste soldering process, low-temperature lead-free solder paste used in the soldering process is called low-temperature solder paste. To prevent components from and PCBThe plate can withstand high-temperature reflow soldering and is deeply resistant LEDFavor from the industry. The particle size of tin powder is25~45 umBetween them, the metal component is SnBi (sn42bi58)Now, let's talk about the characteristics from JJY solder Paste Manufacturer:
