A printed circuit board assembly, in particular for a motor vehicle - transmission control unit, as well as a method for testing an electronic system of the same

摘要

It is a circuit board arrangement (1) is proposed which, in particular for a control unit in a motor vehicle can be used advantageously. The circuit board arrangement (1) has a printed circuit board (3) with an attached electronic system (7) on the printed circuit board (3) printed electronic components (9) as well as a plurality of conductor tracks (13), the electronic components (9) of the electronics (7) with a contact region (15) connect. It is characterized in that in the contact area (15) a plurality of holes (17) are formed and each of the conductor tracks (13) extending up to one of the holes (17), and the holes (17) on a surface (5) of the printed circuit board (3) by means of an adherent film (35) are covered in a hermetically sealed. For testing of the electronics (7) can be a plug (23) with, for example, pin-shaped contact elements (27) directly into the holes (17) are inserted and an electrical contact to a testing device (19) producing. After the testing procedure, the contact region (15) after removal of the plug (23) to be adhered with the aid of the film (35) against soiling and, in particular, be protected by the short circuits.
