Solder paste manufacturer, a brief introduction to the differences between lead-free and leaded processing?

For both leaded and lead-free productionFocusSex, Jia JinyuanSolder paste manufacturerIt has a relatively long history of development, which has led to the current stability of welding and a relatively complete production and processing technology FocusThe main difference lies in the characteristics of leaded solder alloys and lead-free ones.

The melting point and soldering temperature of lead-containing solder are relatively low, and its impact on electronic products is also relatively small. Due to the good plasticity of aluminum alloy with lead solder, the formed solder joints will be better thanLead-free solder pasteThe characteristics of the solder joints should be good.

According to the current results, the processing of lead-free soldering can replace the melting point temperature of alloys, which is higher than that of tin-aluminum alloys. For instance, taking the widely used tin, silver and copper alloys in the industry as an example, their initial melting points are relatively high, which will cause problems in the welding process The process dialog box has been greatly reduced.

In fact, the reduction of the process dialog box can lower the melting point of tin-lead solder. However, in reality, the reduction of the process is much greater than that of the basic one. Because in terms of actual work, the temperature detection methods used by the partners are not accurate enough.
