Excessive gold in the solder joint can create gold embrittlement. This may affect the reliability of the joint. The third PCB pad protective coating option ...
Splet07. sep. 2024 · Gold embrittlement can result in solder joint loss of connectivity that may initially pass electrical testing but later fail during environmental testing or mission operations. It can also result in costly unit rework, reduced mission life, reduced mission data, increased operational complexity, loss of redundancy, and mission failure. As ...
