Embodiment Construction
[0022] figure 1 A cross section is shown through a first exemplary embodiment of a transmission control module 1 according to the invention, which can be built, for example, in an automatic transmission of a motor vehicle. Essentially identical or very similar components are provided with the same reference numerals.
[0023] The transmission control module is intended to be at least partially or fully exposed to transmission fluid (ATF) present in the transmission gearbox and is used to operate regulators and readout sensors in order to operate the automatic transmission. Obviously, the transmission control module can be adapted to the respective required framework conditions, such as the number and type of actuators, sensors and connectors to be actuated. The transmission control module can have a base body (not shown in the figures), which can be formed, for example, from a complex plastic part or a metal carrier plate on which a printed circuit board is mounted. The basi...

The invention relates to a transmission control module (1) comprising a printed circuit board (2) at least partially accessible from the outside and exposed to transmission fluid, with at least one layer on the printed circuit board (2) Conductor lines (41, 42, 43) guided on the top, said conductor lines are used to arrange the carrier substrate (3) of the electronic drive control circuit and the external part of the carrier substrate (3) on the printed circuit board (2) Electric / electronic components (7, 8) are electrically connected, wherein the printed circuit board has at least one inner conductor line layer (26), which is arranged as an intermediate layer between two insulating layers of the printed circuit board (2). Between layers (23, 24). It is proposed to provide at least on the first side (21) of the printed circuit board (2) a first outer insulating layer (23) with a recess (5) at the bottom of which at least one inner conductor line layer ( 26) on the surface of the conductor line sections (41a, 42a) of the conductor lines (41, 42), the carrier substrate (3) is inserted into the recess (5) from the first side of the printed circuit board (2) and connected to the inner conductor Electrically contacting the surfaces of the conductor track sections (41a, 42a) of the wiring layer (26), and filling said recesses (5) with molding compound (6) covering at least the carrier substrate (3) and the conductor track sections (41a, 42a) ), so that the carrier substrate (3) and the conductor track sections (41a, 42a) are protected from transmission fluid by the molding compound (6).
Description
technical field [0001] The invention relates to a transmission control module comprising a printed circuit board at least partially accessible from the outside and exposed to transmission fluid, the printed circuit board having conductor tracks guided on at least one layer of the printed circuit board, said The conductor tracks are used to electrically connect the carrier substrate of the electronic drive control circuit to electrical / electronic components arranged outside the carrier substrate on a printed circuit board, wherein the printed circuit board has at least one inner conductor track layer, the inner The conductor track layer is arranged as an intermediate layer between two insulating layers of the printed circuit board. Background technique [0002] In transmission control, transmission control modules are known which, in addition to the electronic transmission control, have a basic carrier provided, for example, for making electrical contact with actuators, senso...
