Embodiment Construction

[0022] figure 1 A cross-section through an electronic control module according to the invention is shown schematically, as it can be embodied, in particular, on or in a motor vehicle transmission. The electronic control module 1 is designed in such a way that it can withstand transmission oil. The electronic control module 1 in this exemplary embodiment has, for example, a carrier plate 2 . The carrier plate 2 can consist, for example, of metal and preferably of aluminum. For example, a flexible circuit board 3 is applied to the carrier plate 2 . For this, if Figure 4 and Figure 5 As shown in , an adhesive film 16 can be applied to the upper side of the carrier plate 2 and the flexible circuit board 3 is laminated to the carrier plate 2 via the adhesive film 16 . The flexible circuit board 3 has cutouts 9, such as figure 2 shown in . The upper side of the carrier plate, which is coated with the adhesive film 16 , is exposed through the cutout 9 . The electronic circ...

Abstract

The invention relates to an electronic control module (1) comprising a circuit board (3), an electric circuit part (6) electrically connected to said circuit board, a frame section (4) that forms a surrounding wall (40) and has an inner recess (41), said frame section being positioned on the circuit board (3) around the circuit part (6) and stuck to the circuit board (3), a cover section (5), which is positioned on the frame section (4) and welded to the frame section (4) so that a sealed housing interior (13) containing the circuit part (6) is formed. According to the invention, the frame section (4) is designed as a flat plate-shaped laminated part which comprises a first surface (14) and a plane-parallel second surface (15) arranged at a maximum distance (d) of three millimetres to the first surface (14), wherein the first surface (14) of the frame section (4) is laminated on the circuit board by means of a surrounding applied adhesive film (17) and the cover section (5) has a surrounding collar (10) which is placed flat on the second surface (15) of the frame section (4) and welded around to the frame section (4) by means of a welding process.

Description

Background technique [0001] In motor vehicle technology, electronic control modules are used for transmission control, which can be arranged on the transmission and in the transmission fluid. The control module can have, for example, electrical components, such as plugs, sensors, actuators, at least one packaged control unit (TCU, transmission control unit) and possibly other components, which are fastened to a central carrier and subjected to transmission fluid. The arrangement in the transmission fluid places high demands on the construction and connection technology of the structural components on the carrier of the electronic control module, since the electrical connections have to withstand high temperature-changing loads as well as the transmission fluid. In the prior art, injection-molded lead frames and rigid or flexible printed circuit boards (so-called flexible foils) are used as carriers for the electrical connection technology. A particular requirement for use in ...
