The method includes electroplating a first layer on a mandrel, and applying a photoresist to the first layer. The method also includes electroplating a second layer on the first layer adjacent the photoresist, such that the first and second layers form a substantially homogenous structure, and separating the photoresist from the first and second layers to expose one or more flexure recesses where the photoresist was positioned, with the diaphragm having a reduced stiffness proximal the flexure recess.

    摘要: An ink jet print head including a plurality of standoff layer supports in an interstitial region between adjacent piezoelectric elements, and method of formation. The plurality of standoff layer supports can be formed from the same layer(s) as the piezoelectric elements, or from a dielectric layer such as a polymer. The standoff layer supports increase an area to which a standoff layer can be attached, thereby forming a more secure attachment of a circuit layer such as a flex circuit or a printed circuit board to a jet stack subassembly.

    摘要: A method and structure for an ink jet print head which includes the use of two or more flexible circuits and a piezoelectric element array. A first pad array is included on a first flex circuit to power a first portion of the piezoelectric element array of the print head, and a second pad array is included on a second flex circuit to power a second portion of the piezoelectric element array of the print head. Using two flex circuits requires only half as many traces to be formed on each flex circuit, which can relax spacing requirements and design tolerances.

    摘要: A method and structure for forming an ink jet print head having a dielectric interstitial layer. A flexible top plate attached to a press can be used to apply pressure to an uncured dielectric interstitial layer. The uncured dielectric interstitial layer is cured while contacting the uncured dielectric interstitial layer with the flexible top plate and applying pressure using the press. Using a flexible top plate rather than a rigid top plate has been found to form a cured interstitial layer over an array of piezoelectric elements which has a more uniform or planar upper surface. An interstitial layer so formed can result in decreased processing time, reduced problems with ink communication in the ink jet print head during use, and decreased manufacturing costs.
