ABSTRACT:
A flex cable for a head stack assembly of a hard disk drive comprises a base film, a first adhesive layer coupled with the base film, and at least one interrogation trace and at least one signal trace coupled with the first adhesive layer. The interrogation trace is configured to be probed to measure a deterioration of electrical conductivity. The flex cable has a second adhesive layer that is coupled with the interrogation trace, the signal trace, and the first adhesive layer. The flex cable comprises a cover film coupled with the second adhesive layer.
