摘要:
The use of a control module having at least one housing part and a multi-layer printed circuit board as the electrical connection between the inner space of the housing and components that are situated outside of the housing part is described. The multi-layer printed circuit board is the carrier for the electrical components of an electronic circuit, and is at the same time the thermal contacting to a housing part and/or a cooling element, particularly a hydraulic plate of the transmission, for a transmission control installed in an automatic transmission.

An electrical control unit has a printed circuit board substrate, on which an electronic circuit is situated, which circuit includes multiple electrical components which are interconnected via printed conductors of the printed circuit board substrate, as well as housing parts for covering the electrical components on the printed circuit board substrate, and at least one device plug connector part situated on the printed circuit board substrate outside the section of the printed circuit board substrate covered by the housing parts. Outside the section covered by the at least one housing part and outside the section of the printed circuit board substrate provided with the device plug connector part, at least one contact point for an additional electrical component is situated on the printed circuit board substrate.

A device, in particular for use in an electronic controller, includes a card rack and a subassembly. The device is manufactured by soldering over a large area the unpopulated back side of the subassembly to this card rack. The soldering can be performed using a reflow soldering process and can be automated, and thus suitable for mass production. The electrical connections of the subassembly are led spatially and electrically separately from the mechanical attachment of the subassembly to the card rack. The subassembly can be an additional component mounted on the card rack with a new additional function, so that the controller can be flexibly adapted to a given requirement profile in a simple manner by combining, in a flexible manner, a plurality of subassemblies with different layouts and modes of operation on the card rack.

The invention is directed to a method for controlling the idle of an internal combustion engine having an intake channel for conducting air to the engine. The method utilizes sensors for generating signals characterizing the operating state of the engine and for supplying the signals to a control apparatus. A tank-venting valve is provided through which air can be conducted into the intake channel when the tank-venting valve is open. Control quantities are computed in the control apparatus in dependence upon the signals for at least the following: the tank-venting valve, an idle adjuster device, a fuel metering device and an ignition device. The air supplied to the engine is controlled with the aid of the tank-venting valve. The invention is also directed to an arrangement for carrying out the method.

A method for contacting at least one printed circuit board or at least one punched grid and at least one hybrid includes the steps of: forming contact elements in a contacting foil, positioning the contacting foil over the hybrid in such a way that the contact elements are arranged at preselected positions between the printed circuit traces of the hybrid and the printed circuit traces of the printed circuit board, and etching away at least a portion of the contacting foil, such that the contact elements are at least partially freely accessible.
摘要:
In a method for manufacturing a composite arrangement, at least one printed circuit board substrate is joined with a support under the influence of an applied pressure exerted by a press die over a weave layer (prepreg) impregnated with resin, such that the resin in the region of an opening of the printed circuit board substrate does not flow into this opening. The applied pressure is, therefore, at least partially reduced in the region of the opening of the printed circuit board substrate.
