Electronic system for use in transportation medium e.g. motor vehicle, has space formed between housing and electronic component and filled with binding material to absorb water or aqueous fluid resulting from condensation in housing

摘要

#CMT# #/CMT# The system has an electronic component with an electronic unit that is arranged on a carrier, and housing provided for surrounding the electronic component. Expansion space is formed between the housing and the electronic component, and is filled with binding material (8) that is provided for irreversible absorption of water or aqueous fluid resulting from condensation in the housing. The binding material is surrounded by a casing that has surface contour adapted to surface of the electronic component, where the casing has a polypropylene non-woven as an outer layer (9). #CMT#USE : #/CMT# Electronic system for use in a transportation medium e.g. motor vehicle (claimed). Can also be used for an industrial system and a telecommunication system. #CMT#ADVANTAGE : #/CMT# The expansion space is formed between the housing and the electronic component and is filled with the binding material for irreversible absorption of water or aqueous fluid resulting from condensation in the housing such that the water or aqueous fluid does not react with the ionic remainders of the electronic component, and hence the formation of conducting connections and electro migration to the component can be avoided. The reliability of the electronic system can be improved. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic longitudinal sectional view of binding material used in an electronic system. 8 : Binding material 9 : Outer layer 10 : Inner layer 11 : Chambers 12 : Insert.
