IMPROVED PRINTED CIRCUIT WHICH CAN DETECT ACCIDENTAL HEATING

摘要

The invention relates to a printed circuit (10) comprising a support (12) which insulates under the normal operating conditions of the printed circuit (10). The printed circuit (10) bears at least component (14) which can accidentally generate the unwanted heating of a sensitive area (Z) of the support (12). For said purpose, the printed circuit (10) also comprises means for detecting the heating of the sensitive area (Z). The aforementioned detection means comprise means (26) that are sensitive to an increase in the conductivity of the support (12) with temperature.
