China Best Lead Free Core Wire Solder for Electronics & Circuit Boards

What is China Best Lead Free Core Wire Solder for Electronics & Circuit Boards?

Wire solder is a welding material used to connect eletronics such as circuit boards (PCB). It's available in leaded alloy & lead free solder. In China we produce different alloys of lead free solder, such as lead free core solder Sn99.3Cu0.7, lead free core solder Sn99Ag0.3Cu0.7, core wire solder Sn96.5Ag3.0Cu0.5 etc. All are very good solder alloy to work with, and which one is best?

 

Which is China Best Lead Free Core Wire Solder for Electronics & Circuit Boards?

This depends on which aspect you are basing on? Sn96.5Ag3.0Cu0.5 is a silver bearing and the silver adds leak-tight, good electrical conductivity to the solder but on the contrast it's much more expensive because silver is expensive, but product feature and quality of this lead free core wire solder is excellent; Sn99.3Cu0.7 also keeps good quality but not as good as the silver bearing type, while the good thing of it, is this lead free solder can performs reasonable quality when soldering electronics (circuit boards) at a very affordable price. So our conclusion is: Sn96.5Ag3.0Cu0.5 lead free solder is best when you are talking about solder-ability; While Sn99.3Cu0.7 lead free solder is best if we consider it's cost when comparing to it's performance. In most genearal cases for circuit boards assembly, as per our experience, Sn99.3Cu0.7 are used most.
