  • Method of forming a manifold in a substrate and printhead substructure having the same
    Patent number: 6641745
    Abstract: A method of forming a manifold through a substrate of a printhead substructure is disclosed. The substrate has an ink reservoir-facing side and an opposing transducer-supporting side. The transducer-supporting side of the substrate is introduced to an etchant. A laser beam is used to irradiate the etchant contacting side of the substrate. The irradiated areas of the substrate are thereby etched to define a first portion of the manifold therein. A second portion of the manifold is formed, preferably by sand blasting, to connect to the first portion. A printhead substructure that includes a substrate having a manifold formed according to the method is also disclosed.

  • Method of forming a manifold in a substrate and printhead substructure having the same
    Publication number: 20030095166
    Abstract: A method of forming a manifold through a substrate of a printhead substructure is disclosed. The substrate has an ink reservoir-facing side and an opposing transducer-supporting side. The transducer-supporting side of the substrate is introduced to an etchant. A laser bean is used to irradiate the etchant contacting side of the substrate. The irradiated areas of the substrate are thereby etched to define a first portion of the manifold therein. A second portion of the manifold is formed, preferably by sand blasting, to connect to the first portion. A printhead substructure that includes a substrate having a manifold formed according to the method is also disclosed.
