Definitions
- the present invention relates to an electronic control ⁇ er réelle according to the preamble of claim 1 and a method for the arrangement and electrical supply of electronic components on a circuit board according to the preamble of claim 4.
- electronic components are used in electronic control units, in particular motor vehicle control units, in order, for example, to have a
- Vehicle on-board network introduced interference already in the high-current path to filter. Since these components used for interference are often subjected to high currents during operation, a massive design with large diameters of the components associated electrical conductor is necessary, whereby they have a comparatively large amount of space and can be correspondingly difficult. An arrangement and electrical connection of these components on the circuit board in a conventional reflow process, together with other SMD components, is therefore not feasible without considerable additional effort, which is why more joining methods are often used.
- the ends to be contacted, or portions of the electrical conductors of these devices have in this case a large position ⁇ tolerance, resulting in a direct contact with the circuit carrier designed in addition complex.
- Corresponding contact points, z. B. contact openings or. Contact surfaces, the PCB will be without aligning the ends of the conductors thus not directly met.
- Due to layout requirements which specify the orientation and position of components on the circuit carrier, the orientation and position of the contact points of the circuit carrier is also determined with the wired components. In direct contact with the circuit carrier, the ends of the conductors would have to be bent in such a way that they meet the contact points of the circuit substrate, which in many cases can not be realized without considerable effort.
- the object of the invention is therefore to provide a way to ⁇ order and electrical contacting of electronic components, which overcomes the above problems and thereby is possible to produce inexpensively.
- the invention relates to an electronic control unit, particularly a motor vehicle brake system comprising at ⁇ least one circuit carrier for electronic components, wherein at least one electronic component has at least one electrical conductor and further being characterized in that the electrical conductor of the electronic component with at least one contact element mechanically and is electrically conductively connected and the contact element me ⁇ chanically and electrically conductively connected to at least one contact point of the circuit substrate, wherein at least the mechanical and electrically conductive connection of the electrical conductor to the contact element is a connection produced by ultrasonic welding.
- the contact element thus advantageously serves as an adapter between the electronic component and the contact point of the Circuit carrier, whereby a tolerance compensation made possible with a corresponding constructive design of the contact element in combination with the exact ⁇ stechnik of ultrasonic welding ⁇ and a high precision of the positioning of the contact element on the circuit board is achieved.
- This is particularly advantageous for the assembly process of the component, since a prior alignment of the conductor, based on the contact points of the circuit substrate, can be omitted.
- With a corresponding structural design of the contact elements contact points, which are distributed over an extended area of the circuit substrate, be contacted.
- an electrical contacting produced in this way has a low electrical resistance combined with high mechanical strength.
- the ultrasonic welding process is inexpensive to realize because comparatively low investment costs for equipment incurred and no welding consumables are required.
- serial production is particularly advantageous also that very short cycle times can be achieved.
- the contact element and / or the electrical conductor of the electronic ⁇ African component are designed in such a way that the electronic component of the circuit substrate is spaced such that further electronic components, in particular SMD components, in a range between the
- the contact element is designed as a press-in contact comprising at least one press-in region, which is pressed in at least one designed as a contact opening Kon ⁇ timing location of the circuit carrier.
- the invention further describes a method for assembly and electrical connection of at least one electronic component on a circuit substrate of an electronic control device, in particular a control device for a motor ⁇ vehicle braking system, which is characterized in that at least a region enclosed by the electronic component is an electrical conductor with at least one contact element me ⁇ chanically and electrically conductively connected and the contact element is mechanically and electrically connected to at least one contact point of the circuit substrate, wherein at least the mechanical and electrically conductive connection of the electrical conductor of the electronic component with the contact element is produced by ultrasonic welding.
- FIG. 1 shows an exemplary embodiment of the arrangement according to the invention and contacting of an electronic component using the example of a current-compensated choke coil
- FIG. 2 shows examples of electronic components provided for arrangement and contacting.
- Fig. 1 shows an embodiment of the inventive arrangement and contacting of an electronic component with a relatively large wire diameter on circuit substrate 5, the example of a current-compensated reactor 1.
- ⁇ spielsdorf choke coil 1 serves to limit disturbances in a motor vehicle control unit, which, for example, introduced via a vehicle On-board power supply, which can influence the electronics of the control unit.
- choke coil 1 comprises at least one electrical conductor 2 whose ends 6 and / or regions thereof are electrically and mechanically connected to press-fit contacts 3, as described generically, for example, in DE 10 2009 025 113 A1.
- the arrangement of choke coil 1 and press-fit contacts 3 is shown in the contact openings 4 of circuit carrier 5 before pressing in the press-in zones of the press-in contacts 3. After press-fitting of the press-fit zones of the press-fit contacts 3 into the contact openings 4, there is a mechanical fixation of the choke coil 1 on the circuit carrier 5 as well as an electrical-functional connection thereof.
- the electrical and mechanical connection of the electrical conductor 2 with the press-in contacts 3 is preferably produced according to the invention by means of ultrasonic welding. .
- the joining partners unlike many other welding processes, are not heated to the melting point.
- the connection of two or more elements to be welded is instead produced by an intermetallic compound, whereby the heat input into the weld metal and the thermal distortion are low.
- the press-fit contacts 3 can be precisely oniert positi ⁇ during the assembly process, to perform the press-in accordingly.
- the generated connection between conductor 2 and press-in contact 3 does not fix this exclusively mechanically but also realizes also an electrical contact whose electrical contact resistance should be as low as possible. This requirement can be met in particular by means of contact seams produced by ultrasonic welding. Furthermore, only small demands on the surfaces of the welding partners are required, which makes expensive pretreatments dispensable.
- the dimensioning or design specification of the press-fit contacts 3 is such that the choke coil 1 is spaced from the circuit carrier 5 in such a way that on the circuit carrier 5 further electrical components (not shown), in particular SMD components, can be provided in the region between reactor 1 and circuit carrier 5.
- Fig. 2 a shows another electronic component on the example of rod core coil 7, while in Fig. 2 b) choke coil 1 is again shown separated.
- Fig. 2 a shows another electronic component on the example of rod core coil 7, while in Fig. 2 b) choke coil 1 is again shown separated.
