PCBA Knowledge:

As more and more lead-free electronic products go on the market, reliability issues have become the focus of many people's attention. Unlike other lead-free related issues (such as alloy selection, process windows, etc.), we often hear very different opinions on reliability. In the beginning, we heard many “experts” saying that lead-free is more reliable than tin-lead. Just when we believe it is true, there are "experts" who say that tin-lead is more reliable than lead-free. Which one should we believe in? This depends on the specific situation.

PCB lead-free solder interconnect reliability is a very complex issue that depends on many factors.
