Abstract

Corrosion control in electronics and know-how concerning various protection methods have become an important field of design since electronics is increasingly used as integrated into different devices in highly corrosive conditions. On the other hand, the increase of the packaging density of electronics has resulted in electronics that is sensitive to the corrosive effects of the environment even in milder conditions. The project charted the mechanisms through which the climate, humidity, contamination, other environmental factors, the way of use of the device and its structure as well as the manufacturing process affect the corroding and faults of the electronics. A method was developed for solving these problems by which both the experienced and the beginning designer can check the feasibility of the applied corrosion protection technique and foresee possible corrosion problems in the structure of the device as well as find new approaches for solving them. The report also presents an evaluation method for the corrosive effect of the usage environment. In addition, various types of corrosion mechanisms and protection against them are described, corrosion analysis and measurement methods introduced and testing methods used for quality assurance regarding corrosion discussed. Comprehensive lists of standards and literature concerning corrosion and climatic effects are appended to the report.
