Abstract
The invention relates to a printed circuit (10) comprising a support (12) that is insulating under normal conditions of operation of the printed circuit (10). The printed circuit (1) carries at least one component (14) that is capable of accidentally causing undesirable heating of a sensitive zone (Z) of the support (12). For this purpose, the printed circuit (10) further includes a detector for detecting heating of the sensitive zone (Z). The detector comprises a device (26) that are sensitive to the increase in the conductivity of the support (12) with temperature.
