1 shows a first embodiment of the control device according to the invention. The control unit is, for example, a transmission control unit which can be installed in a control module mounted on the transmission. The controller has a carrier 1 on, which is formed for example as a flat metallic support plate made of steel or aluminum with good heat dissipation. The carrier 1 can be set to the control module, not shown, where it is connected in particular thermally conductive with a heat sink of the module. As in 1 continues to recognize is on the carrier 1 an electronic circuit part 2 applied. The electronic circuit part 2 comprises an electronic circuit arranged on a carrier substrate with electrical and / or electronic components which are required for controlling the transmission. The circuit part is preferably formed as LTCC (Low Temperature Cofired Ceramic) with a ceramic carrier substrate and is for example via an adhesive layer 6 or otherwise on the carrier 1 applied. As in 1 and 2 can be seen, is also at least one flexible conductor foil 3 on the carrier 1 laminated, with an adhesive 24 is used. Advantageously, a plurality of flexible conductor foils 3 . 3 ' . 3 '' be laminated in strip form on the common carrier. By gluing the conductor foils 3 . 3 ' . 3 '' on the level mounting side of a common carrier 1 a slight positional tolerance of the conductor foils to each other can be maintained. The flexible conductor foils 3 . 3 ' . 3 '' are at their remote from the carrier and in 1 and 2 Not shown ends contacted with electrical or electronic components of the control module. These include, for example, sensors, plug parts or hydraulic valves. Gluing the conductor foils 3 . 3 ' . 3 '' serves the mechanical attachment to the carrier and the strain relief of the electrical connection points to the circuit part 2 , Through the glue 24 is also advantageously achieved that tensile forces act not only on the sealant on the control unit housing. The conductor foils can also be applied before applying the circuit part 2 on the carrier 1 be laminated.
As in 1 and 2 is further shown, after mounting the conductor foils, a preferably metallic frame part 5 put on the carrier. The frame part can also be made of plastic. The frame part 5 has a trough-like shape with an interior recess 18 and so gets on the carrier 1 put on that the electronic circuit part in the inner recess 18 is arranged and the circuit part 2 on four sides of the frame part 5 is surrounded. The frame part 5 has a first substantially flat wall portion 11 on, which is roughly parallel to that with the circuit part 2 provided side of the vehicle 1 is arranged. The first wall section 11 has a the carrier 1 facing first page 11a and a second side facing away from it 11b on. The frame part further comprises one of the first wall portion 11 bent second wall section 12 on, which forms a laterally encircling boundary wall of the control unit housing and with a collar 13 is provided. The first wall section 11 is with recesses 15 . 15 ' and 15 '' for the implementation of electrical connection means 7 Mistake. Between the first wall section 11 and the conductor foils 3 . 3 ' . 3 '' is a surrounding the respective recess sealant 8th . 8th' . 8th'' intended. As a sealant, for example, an adhesive seal in the form of a circumferential Dichtkleberbefulstes in question, on the one hand after the application on the respective conductor foil 3 . 3 ' . 3 '' remains dimensionally stable and does not run and on the other hand has a sufficiently low viscosity to after placing the frame part 5 completely wet the respective conductor foil and the frame part in the sealing area. The amount of used-up sealing adhesive is measured according to the width and height of the gap between the conductor foil and the frame part 5 , Every sealing glue bead 8th . 8th' . 8th'' is each on the associated conductor foil 3 . 3 ' . 3 '' around with the contact surfaces 30 circumferential area of the conductor foil, as best shown in FIG 2 can be seen. Subsequently, the frame part 5 be set and cured the sealing adhesive.
At the electronic circuit part 2 facing and from the second wall section 12 facing away from the inside of the first wall section 11 is one to the carrier 1 bent down section 14 arranged on which an approximately parallel to the carrier extending investment area 16 connects, for example, with a rib 16a rests directly on the metallic support and the inner recess 18 border. The attachment of the frame part 5 on the support can be welded on the contact area 16 with the carrier 1 in the rib area 16a respectively. This can be carried out in particular as resistance welding (capacitor discharge welding) or as laser welding. It is advantageous to the electronic circuit part 2 only after the verscheißen of the frame part 5 with the carrier 1 apply to the carrier to avoid possible damage to the sensitive circuit part by the welding process.
After welding the frame part 5 with the carrier 1 and the application of the circuit part 2 become Bondlands of electronic circuit part 2 with the contact surfaces 30 the conductor foils 3 . 3 ' . 3 '' via electrical connection means 7 contacted in the form of bonding wires. For this example, aluminum bonds can be used. After the bonding wire connection has been made, the circuit part can be provided with a gel cover. This is a first gel 26 (For example, a low-cost standard gel) applied to the circuit part. By the to the carrier 1 towards bent section 14 of the frame part 5 a gel uptake is created upon application, thereby preventing the gel from reaching the first wall portion 11 to get. In the area of the recesses 15 . 15 ' . 15 '' can therefore be a second gel 27 be applied with a different consistency (for example, a high-resistant fluorinated gel), that of the respective sealant 8th . 8th' . 8th'' enclosed space above the contact surfaces 30 up to the height of the respective recess 15 . 15 ' . 15 '' fills, eliminating the contact surfaces 30 to be protected.
The bent section 14 prevents the first gel and second gel from running into each other. The first gel 26 and the second gel 27 can be cured together, using the not yet closed frame part 5 advantageously a vent occurs.
Finally, a housing cover 4 on the frame part 5 placed. The housing cover has a circumferential rib 4a on that on the collar 13 of the frame part 5 comes to the plant. In this area is the frame part 5 with the housing cover 4 welded, creating a closed housing interior 9 arises. The housing cover can also be set in a different form to the frame part. For example, by crimping or sealing. carrier 1 , Frame part 5 and housing cover 4 can be advantageously prepared from the same metallic material. Due to the same coefficients of expansion, the thermally induced stresses on the polymer seals between the conductor foil and the frame part are minimized.
A second embodiment is in 3a and 3b shown. In this Ausfüh Example, the first wall section 11 of the frame part 5 seen from the housing interior with recesses 25 provided on the carrier 1 facing side 11a of the first wall section 11 form projections projecting towards the carrier, which pass through recesses of the conductor foils directly on the carrier 1 rest and with this for mechanical fixing of the frame part 5 on the carrier 1 be welded.
A fourth embodiment is in 4 shown. In this embodiment, a sleeve-like spacer 20 plastic in the recess 15 of the frame part 6 pressed. Through the spacer 20 becomes the distance between the first wall section 11 of the frame part 5 and the flexible conductor foil 3 set. The spacer 20 has an internal recess 21 on, through which the electrical connection means 7 through with the contact surfaces 30 the conductor foil 3 are contacted. The sealant 8th is formed in this embodiment as a compression seal in the form of a fluorinated elastomer, which under radial prestress on the spacer 20 is postponed. The spacer therefore serves both as an assembly aid for the sealant 8th as well as to set a defined compression of the sealant 8th ,
Furthermore, in this embodiment, another wall section 19 of the frame part 5 provided, attached to the collar 13 connects to the vehicle 1 is angled away and with a parallel to the carrier 1 extending bent portion 22 is provided. The section 22 is with fasteners 23 , For example, in the form of screws or rivets fixed to the carrier. Of course, the section 22 also with the carrier 1 be welded, the weld also as in 3b can be executed shown.
In the design of the sealant 8th . 8th' . 8th'' In the form of compression seals there is the further possibility of the sealant to the frame part 5 to spray or form by vulcanization of the frame part. This raises another advantage. Save the sealants 8th In addition, the seals between the frame part and the housing cover or between the frame part and the carrier can also be designed as compression seals. Advantageously, in this case, the vulcanization of the seals can be carried out separately from the conductor foil, whereby resulting reaction products do not affect the cleanliness of the contact surfaces of the conductor foil.
