Adhesively attached hard disk head suspension and etching process

摘要

A head gimbal assembly for disk drives is attached to an actuator arm using an adhesive. An etch pattern is formed in the mount plate of the head gimbal assembly, defining a mating surface area. An actuator arm is received by the mating surface area, the two members are suitably aligned, and an adhesive is introduced into the various channels that comprise the etch pattern through an access opening that is located outside of the mating surface area. By locating the access opening outside of the mating surface area, the adhesive may be introduced after a final alignment is achieved between the head gimbal assemblies and the actuator arms. Such manner of attachment may be used with individual actuator arms as well as when connecting head gimbal assemblies to an actuator comb assembly.
