Description

[03/2021]

During their production and use in the field, electronic equipment and assemblies are exposed to the influence of moisture and environmental conditions (air, weather, location of the assembly, storage and cleaning). Air, humidity and water lead to an electrically conductive connection of adjacent metal surfaces, which may have different electrical potentials and may thus cause disorder of the electrical insulation by developing additional electrical paths.

Reliability of an electronic product and customer satisfaction are of utmost importance for the success on the market. Product liability requires the manufacturers to take the necessary steps in order to ensure safe operation of electronic equipment also under such heavy conditions. This mainly applies to assemblies which are used in space technology and aviation , defence technology, medicine and automotive industry.

This Whitepaper-Collection contains a selection of papers discussing field failures caused by climactic stresses and the selection of a protective concept. A special focus is set on the topics electrochemical migration (ECM) and protective coating.
