  • Substrate for fluid ejection devices
    Patent number: 6997540
    Abstract: A fluid ejection assembly includes a substrate and a plurality of fluid ejection devices each mounted on the substrate. The substrate includes a frame formed of a first material and a body formed of a second material such that the body substantially surrounds the frame and forms a first side and a second side of the substrate with each of the fluid ejection devices being mounted on the first side of the substrate.
    Type: Grant
    Filed: October 8, 2003
    Date of Patent: February 14, 2006
    Assignee: Hewlett-Packard Development Company, L.P.
    Inventors: Janis Horvath, Brian J. Keefe, Joseph E. Scheffelin, Mohammad Akhavin, David K. McElfresh, Noah Carl Lassar
  • Method of forming substrate with fluid passage supports
    Patent number: 6880246
    Abstract: A method of forming a fluid ejection assembly includes providing a substrate including a plurality of layers and having a plurality of fluid passages extending through the plurality of layers, extending a support between opposite sides of each of the fluid passages, and mounting a plurality of fluid ejection devices on the substrate, including communicating each of the fluid ejection devices with one of the fluid passages.

  • Edge-sealed substrates and methods for effecting the same
    Publication number: 20040087063
    Abstract: Methods and systems of protecting substrates that are intended for use in fluidic devices are described. In accordance with one embodiment, sealant material is applied over one or more edges of at least one multi-chip module substrate that is intended for use in a fluidic device. At least one edge has an exposed electrical interconnect and the sealant material is applied over less than an entirety of the substrate and sufficiently to cover the exposed electrical interconnect. The sealant material is exposed to conditions effective to seal the one or more edges.
