Appl. No.:

10/293133

Inventors:

Philip Entingh - Ontario NY, US

International Classification:

B41J002/05

US Classification:

347/065000

Abstract:

An ink printing acoustic print head. The ink printing acoustic print head prints ink on a print medium. The ink printing acoustic print head has a fluid distribution manifold and a fluid distribution stack in fluid communication with the fluid distribution manifold. A front membrane has a print work area. The front membrane is sealed to the fluid distribution stack. An acoustic array having droplet emitters is fixedly located between the front membrane and the fluid distribution stack with the droplet emitters facing the print work area. Ink is transferred from the fluid distribution manifold through the fluid distribution stack and to the print work area. Droplets of ink are emitted from the print work area by selectively energizing the droplet emitters.

Abstract:

A method of forming a fiducial in a stencil for screen printing and the stencil so formed is described. A target fiducial thru-hole of a first size is formed in the stencil, the surface of the stencil in an area around and larger than the size of the target thru-hole is electrochemically etched, and the target fiducial thru-hole is filled with a filling material. The target fiducial thru-hole, included as part of the stencil pattern, is used as a target to which the fiducial mask, used in the electrochemical etching, can be aligned to. The target fiducial thru-hole may be made smaller than previously feasible because the fiducial is electrochemically etched, which means that it cannot fall out of the stencil. The filling in the target fiducial thru-hole is less likely to fail since it has a drastically decreased surface area to wall thickness area ratio compared to conventionally formed fiducials.
