What are the differences between high-temperature solder paste and low-temperature solder paste? JJY is here to popularize knowledge for everyone

High-temperature solder paste andLow-temperature solder pasteWhat's the difference? Questions that seem easy to answer are not easy to answer.JJYLet everyone know.

Low-temperature tincreamAs the name suggests, its melting point is relatively low. Its main components are tin and bismuth, with solder paste addedBIAfter that, the temperature will drop its melting point138℃. Applicable to components that cannot withstand high temperatures orPCBLow-temperature solder paste has relatively poor solderability, brittle solder joints and dull luster.

High-temperature solder paste has a relatively high requirement for temperature when passing through the furnace, and its melting point should be higher thanSN/BISolder paste, higher79℃The above main components are composed of tin, silver and copper, with a melting point of217℃-227℃That's all. It is widely used, has good weldability, is hard and firm, has good mechanical strength, and the weld points are bright.

JJYHigh-temperature solder pasteThe tin climbing effect is good and the service life is long. High activity, low porosity, and not prone to collapse; The solder joints are full and bright, with high strength and excellent electrical conductivity. Excellent printing performance and demolding performance, with fine pin spacing, mounting is effortless. It adopts imported flux and can be printed for a long time without affecting the wettability and viscosity of the solder paste.
