Abstract
A method to salvage suspensions from defective head gimbal assembly units is presented. Because the performance of a slider becomes more sensitive to signals and the wafer manufacturing process produces a lower yield, a suspension salvage method is developed to recycle a damaged head gimbal assembly in order to minimize material loss. In one embodiment, the salvage method includes separating a gold ball from a bonding pad of the suspension, twisting off the slider attached to the suspension, and dissolving the remaining epoxy.
