Electrical connection and method for establishing electrical connection

Abstract

The invention relates to electrical connections and methods for establishing electrical connections. An electrical connection is established between at least one in-line packaging component disposed on the circuit board having at least one connection pin inserted into the circuit board through-sleeve and the flexible wiring path. Between the connecting pins of the in-line packaging component, the flexible wiring path and the through-sleeve there are electrically conductive connection points for electrical contact. The electrical connection allows the transmission control unit (“TCU”) with a large number of connection pins or the connection pins of any electronic module to continue to contact the flexible wiring path and make the electrical connection between the connection pins of the “TCU” and the through sleeve inside the circuit board. The wiring path is formed with a conductor track film, which has a plurality of conductor tracks arranged between the cover films and extending substantially parallel to one another and evenly spaced apart. Therefore, only one soldering point is still required for each connection pin, which can be produced in any number at the same time with the so-called "selective" soldering method starting from the soldering side of the circuit board by means of the same soldering method.

Description

technical field [0001] The invention relates to electrical connections and methods for establishing electrical connections. Background technique [0002] In modern motor vehicles an ever-increasing number of system components are electronically adjusted and / or controlled. To optimize fuel consumption, for example, electronically controlled automatic transmissions are widely used. The electronic transmission controller (the so-called " T transmission C ontrol U nit"="TCU") with a large number of electronic and electrical components soldered into conventional circuit boards (so-called " P rinted C circuit B oard” = “PCB” and is enclosed in a sealed manner by the housing. Due to the hermetically sealed housing, the “TCU” can, for example, be placed directly in the transmission oil sump. The “TCU” contains often complex hybrid circuits, such as those constructed on ceramic substrates (so-called " L ow T temperature C of fire C eramic" = "LTCC"). [0003] In order to ...

Problems solved by technology

[0005] The main disadvantage of this aforementioned connection technique is that for each connection pin of the "TCU" that is to be further contacted, two soldering points have to be produced in each case.

In addition, the brazing joints often may not be produced at the same time and with the same brazing technique, resulting in high processing and cost outlays
