. Generally, the larger the size of the same category, the greater the stress release and the relatively weaker high temperature resistance

. Requirements for resistance to thermal fatigue are a priority for the products of many high reliability end users [6]. Solder joints age and degrade during service and eventually fail by the wear out mechanism of thermally activated solder fatigue (creep fatigue) [7

. They’re made of layers of materials, including tin-lead, nickel, and gold. They have to have high conductivity to keep the system working well
