| 摘要 |
The invention relates to an apparatus (1) for monitoring a printed circuit board (3), which has an electronic and/or electrical circuit having at least one conductor track (5, 7) for transmitting signals and/or supplying energy and having at least one component, comprising at least one measuring structure (20) which is arranged on the printed circuit board (3) and is electrically connected to an evaluation and control unit (10), wherein the evaluation and control unit (10) records at least one physical variable of the at least one measuring structure (20) and evaluates said variable for the purpose of detecting errors. In this case, the at least one measuring structure (20) is arranged in a predefined region (3.1) of the printed circuit board (3) to be monitored, wherein the evaluation and control unit (10) detects a structural change (CAF) in the printed circuit board (3) and/or the at least one conductor track (5, 7), which is caused by environmental influences, by evaluating the at least one physical variable of the corresponding measuring structure (20). |
