Basics

In general, semi‐conductors have an almost infinite life if they are used
within their specifications.
As a result of thermal load, however, mechanical forces act on the
semi‐conductor chips, and this may influence their life depending on the
component size.
For this reason, semi‐conductor manufacturers normally provide life
curves showing the number of temperature cycles until the calculated
end of life – in dependence on the junction temperature rise. In this
case, one temperature cycle corresponds to one spot weld.
