In the electronics industry, the solder that is used more frequently is6040and6337This type of solder has a development history of several decades, and its manufacturing process is also relatively mature and complete. From this, it can be seen that to replace lead-containing solder, some sufficient conditions must be met, Jia JinyuanSolder paste manufacturerLet's analyze what these conditions are?

    From the requirements of the electronics industry for soldered components, what needs to be taken into account is the ability to better avoid damaging most of the characteristics of electronic components, which is relatively commonLead-free solderIts melting point should be as close as possible to that of tin-lead eutectic solder. When the melting point is high, the solder will exceed the heat resistance temperature of electronic components, which will affect the reflow soldering furnace.

    From this, it can be seen that using solder with a high melting point is not feasible. Secondly, from the perspective of forging performance, it can be related to electronic components,pcbThe coating of the board has relatively good wettability.

    From the perspective of product reliability, it is necessary to be able to achieve relatively good spot welding in the industry. The fracture toughness of the solder itself is also very important. When spot welding is required to have heat-resistant characteristics, due to the application of electronic products, the entire process is bound to cause heat generation, which in turn leads to deformation.
