Beschreibung
Zusammenfassung:	A method of fabricating a base plate for piezoelectric actuation, comprises providing a plate having a major surface, striking a first removable portion of the plate in a first direction substantially normal to the major surface to shear the first removable portion relative to the plate by a shear distance that is less than the plate thickness. Striking the first removable portion in a second direction substantially opposite the first direction to reduce the shear distance by a reduction in shear that is less than the plate thickness. Leaving it the first removable portion in place rather than removing. Alternately, the removable portion may be created by lancing one or more portions spanning at least one opening through a base plate adjacent a first side of at least one opening and adjacent a second side of the at least one opening.
