ABSTRACT:
A disc drive flex circuit head interconnect includes a base dielectric layer, a plurality of electrical conductors disposed on the base dielectric layer, and a displacement limiter coupled to the base dielectric layer. The displacement limiter is adapted to contact a disc drive load beam when the interconnect is displaced a selected distance.
A disc drive head suspension assembly includes a load beam, a flex circuit head interconnect, and a head. The load beam has a tongue with a distal end and a dimple extending downwardly therefrom. The flex circuit head interconnect is disposed on the load beam, the interconnect has a base dielectric layer, a plurality of electrical conductors disposed thereon, and a head attach region. The head has a top side and an air bearing surface bottom side, the head is coupled to the head attach region of the flex circuit head interconnect such that the head gimbals about the dimple. The flex circuit head interconnect includes a displacement limiter disposed proximate the head attach region, the limiter contacting the tongue when the head is moved a predetermined distance away from the dimple.
