Abstract
A method of assembly a dual stage actuated suspension includes either applying an adhesive to a microactuator motor and then B-staging, it or applying an adhesive that has already been B-staged such as in film adhesive form, then assembling it to a microactuator and then finishing the adhesive cure. The method allows greater control over how much adhesive is used, and greater control over spread of that adhesive, than traditional liquid epoxy dispense methods. Additionally, a suspension is provided that has a wrap-around electrode such that both the driving voltage and the ground, which are normally connected at different sides of a PZT, can be connected at the same side of the PZT, thus simplifying electrical connections to the PZT.
