SOLDERABILITY OF TERMINALS AND AGING.
Abstract
The study involves two main objectives. First, to develop an artificial aging method which can be used to simulate six to 12 months of natural aging for solderable terminations. Second, to develop a solderability test method for lugs, tabs, large terminals and stranded wire; there is not test at the present time for these types of terminations. Part I of the study involved an evaluation of both naturally and artifically aged samples and an attempt at correlating the results of each evaluation. The results show that exposure to steam under controlled conditions for one hour is nearly equivalent to six months of average natural aging on common finishes. A steady state humidity condition was shown to have the next best correlation to natural aging. Part II of the study involved the evaluation of a number of techniques which could eventually be developed into a test method. In addition, two recent solderability specifications were also studied.
