Abstract: A dual stage actuated (DSA) suspension includes a dam-like structure that holds epoxy along the outside lateral side of the PZT microactuators while that epoxy hardens. In the illustrative embodiment, the dam-like structure is in the form of a wing rail that is integrally formed with the suspension base plate, and extends parallel to the outside face of the PZT. The wing rail has an upturned edge to help contain the epoxy while it hardens. The wing rail has springs at its fore and aft ends so that the rail does not unduly limit movement of the PZTs and hence microactuator stroke length. The wing rail does not touch the PZT electrodes. The encapsulation dam allows epoxy to be dispensed after the PZT has been located on the suspension, so as to substantially cover all sides of the PZT and thus prevent the shedding of contaminating particles during operation.
