ACCELERATED CORROSION TESTING OF ELECTRONIC COMPONENTS - A DEVELOPING SCIENCE

摘要

The need for long term reliability in highly complex electronic equipment has led to an increase in the use of accelerated corrosion tests to predict the useful life of electronic components and equipment in the actual use environment. Examples of some of the simulated test environments more commonly used are described and typical problems areas common to most accelerated corrosion tests are identified. Without quantitative comparisons between the results obtained in simulated and real environments, the variety and complexity of and the time dependent variables existing in most field environments make absolute life predictions problematical.
