Claim 0:
1. A method, comprising:
soldering a soldered element onto a solder pad of an integrated circuit;
wherein said integrated circuit includes a structure underlying the solder pad, said structure including a network of first parallel metal tracks under and electrically connected to the solder pad and a detection electrical path formed by second metal tracks under the solder pad and insulated from and passing between the first parallel metal tracks; and
testing production control of the integrated circuit by:
performing a test on the detection electrical path to measure a quality which is indicative of a presence of a crack in the detection electrical path caused by soldering the soldered element onto the solder pad; and
performing a decision phase based on the measured quality to generate a signal indicating whether said crack is present.
