SCHUTZVORRICHTUNG FÜR SCHALTUNGSTEILE UND/ODER DATEN IN EINEM ELEKTROTECHNISCHEN GERÄT

摘要

A flexible printed-circuit board (3, 4) having at least two conductor layers (8, 10) completely surrounds an apparatus which is accommodated in a housing (1, 2). The conductors in the individual levels run in a meandering shape and have a preferred direction. The preferred directions of the conductors differ in the successive conductor layers (8, 10). Temperature changes, voltage changes and negative influences on the conductors are identified by an evaluation circuit. The evaluation circuit erases the data memory.
