Abstract
To make housings used in automotive engineering for holding electronic components suitable for engine compartment installation, complex measures are taken that involve high manufacturing costs. In accordance with the invention, a housing is provided that permits simple production at low cost and affords dependable protection of the electronic systems, in that the electronic components mounted on an electronic carrier are provided with a protective lacquer, and then covered with a flexible and watertight foil as a protection against moisture in such a way that it provides an airtight and watertight seal on an all-round edge formed by a metal plate supporting the electronic carrier. A housing cover forming the housing in conjunction with the metal plate serves as a mechanical protection.
Claims18
A housing containing electronic components for use in motor vehicles wherein:
- said electronic components are disposed on an electronic carrier which is one of a PCB, a film or a hybrid carrier;
- a metal plate is provided to accommodate said electronic carrier, with the are of said metal plate having a larger area than said electronic carrier in order to form an edge all round said electronic carrier;
- the surface of said electronic carrier provided with said electronic components is provided with a protective lacquer;
- as a protection against moisture, a flexible and watertight film is spanned over the array formed by said metal plate and said electronic carrier provided with said electronic components such that said film is connected to said all-round edge in an airtight and watertight fashion and is largely matched to the surface contours of said electronic components;
- and
- a housing cover is provided as a mechanical protection and forms said housing in conjunction with said metal plate.
A housing containing electronic components for use in motor vehicles comprising:
- a carrier having a plurality of electronic components disposed on a surface of said carrier;
- a metal plate having an area of which is larger than that of said carrier, said carrier being disposed on a surface of said metal plate to form an edge area extending all around said carrier;
- a protective lacquer covering said surface of said carrier provided with said electronic components;
- a flexible and watertight film spanned over the array formed by said metal plate and said carrier provided with said electronic components and connected to said edge area all around said carrier in an airtight and watertight fashion, said film having a shape largely matched to the surface contours of said electronic components;
- and
- a housing cover, provided as a mechanical protection, extending over said film and connected to said metal plate to form the housing;
