Printhead layer design for compatibility with wet adhesive application processes

摘要

The printhead can include a nonwebbed diaphragm layer, an aperture plate layer, and a first webbed layer and a second webbed layer interposed between the diaphragm layer and the aperture plate layer. The nonwebbed diaphragm layer can be configured to deflect and eject ink from the print head during printing. The aperture plate layer can include a plurality of nozzles from which ink is ejected during printing. Each of the first and second webbed layers can include a first surface having a first surface area and comprising a plurality of first openings, a second surface opposing the first surface and comprising a plurality of second openings, and a web comprising a portion of the first surface, a portion of the second surface and a plurality of holes extending between the plurality of first and second openings. The printhead can be formed, in part, of alternating webbed and adjacent nonwebbed layers.

1. A print head, comprising:
a nonwebbed diaphragm layer configured to deflect and eject ink from the print head during printing; an aperture plate layer comprising a plurality of nozzles from which ink is ejected during printing; and each of a first webbed layer and a second webbed layer interposed between the diaphragm layer and the aperture plate layer; wherein each of the first and the second webbed layers comprise
a first surface having a first surface area and comprising a plurality of first openings;a second surface opposing the first surface and comprising a plurality of second openings; anda web comprising a portion of the first surface, a portion of the second surface and a plurality of holes extending between the plurality of first and second openings,wherein each of the plurality of openings comprises a cross-sectional area,wherein a sum of the cross-sectional areas of the plurality of first openings comprises more than about 35% of the first surface area, andwherein a solid surface area of the web comprises less than about 65% of the first surface area.
