Abstract
An electronic assembly includes an electronic module and an electric part. The electronic module includes an electrically conductive press-fit terminal. The electrically conductive press-fit terminal has a press-fit section. The electric part has a contact hole. The press-fit section is inserted in the contact hole and plastically deformed therein, such that the press-fit section both mechanically and electrically contacts the electric part in the plastically deformed state. A corresponding method of assembly is also described.
Claims26
A method, comprising:
- providing an electronic module comprising an electrically conductive press-fit terminal, the electrically conductive press-fit terminal comprising a press-fit section;
