Said connection element (21) is a part of the base area (20) and is arranged at an angle (a) to the base area (20), in addition to at least one electronic component (3), in particular a sensor, which is arranged in the connection element (21).

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to an electronic module, as, for example, a transmission controller for motor vehicles, as well as to a method for the production thereof.[0002]In the prior art, a plurality of sensors is required at multiple locations, for example, in transmission control systems in order to acquire different signals, as, e.g., temperature, pressure and rotational speed. Feed lines to said sensors consist, for example, of flex foils or cables and are connected to the transmission controller which typically comprises a small printed circuit board. As a result, a very large assembly outlay is incurred and the necessary connections between sensors and printed circuit board are relatively expensive. In addition, a large number of procedural steps, as, e.g., bonding, soldering, welding or adhesive bonding, are required. It would therefore be desirable to provide a cost effective electronic module which particularly can be used in transmissio...

Benefits of technology

[0003]The inventive electronic module has in contrast the advantage that a cost effective electronic module which can easily be equipped can be provided, wherein electronic and / or electric components, in particular sensors and / or actuators, can be disposed at arbitrary positions. According to the invention, a cost effective, extensive support plate, e.g. a printed circuit board, or a ceramic or a substrate, can be used. As a result, the components can be mounted in a normal surface-mount process (SMT process) and therefore very cost-effectively. This is achieved according to the invention by the fact that the support plate comprises a base area and a connection element. The connection element is a part of the base area and is arranged at an angle to said base area, i.e. said connection element is integrally formed with the base area and protrudes from said base area. The connection element is arranged by bending the base area upward at an arbitrary angle to said base area. According to the invention, at least one component is thereby disposed on the connection element. By bending the connection elements upward from the base plane, a component can therefore be disposed according to the invention at an arbitrary position and at an arbitrary distance from the base plane. As a result, different sensors can, for example, be disposed at various positions which are spaced differently from the base area, only one single support plate being necessary in this arrangement. Temperature sensors, pressure sensors or rotational speed sensors can, for example, be used as sensors. The connection elements are preferably bent at an angle of 90° to the base area. Any other angle is, however, also conceivable.

[0005]The component is furthermore preferably disposed in an end portion of the connection element. In addition, the connection element and / or the support plate is surrounded by a sealing compound or the like. As a result, the connection element can be quickly and simply fastened to a counter body.

[0007]In a further preferred manner, the electronic module comprises a base plate, in particular a sheet metal plate, wherein the support plate is disposed on the base plate, in particular laminated to said base plate. As a result, the electronic module gains stability on the one hand and the base plate can furthermore be used for cooling. The region of the base plate located under the connection element is likewise preferably exposed and bent.
