Recent growth of surface mount technology, and especially the miniaturization in microelectronics, have significantly changed the basic functions of solders. Their role of providing mechanical support to devices on circuit boards has become more and more critical compared to their traditional purpose of providing electrical contact.

Also, the processing and service temperatures for solders are generally higher now with respect to their absolute melting points. Furthermore, thermal cycling caused by processing of circuit boards at high temperatures, fluctuating temperatures in the ...
