Abstract
A dual stage actuated suspension has microactuators that are adhered to the suspension by adhesive such as epoxy. The epoxy is contained within an adhesive containment vessel defined by walls of an insulating material such as polyimide. Adhesive overflow channels are formed within the polyimide to receive and channel any excess epoxy that overflows over the polyimide wall. The channels may have increasing width to help draw the excess epoxy toward a centrally located reservoir.
