A method of manufacturing a print head includes forming a jet stack, the jet stack including a nozzle plate having an array of nozzles, attaching an array of transducers to the jet stack, wherein the array of transducers has a transducer corresponding to each nozzle, adhering an adhesive layer to the array of transducers, forming opening in the adhesive layer, each opening adjacent a transducer in the array of transducers, partially removing the adhesive layer in regions adjacent the openings, such that the adhesive layer is less thick in the regions adjacent the openings than in other regions, and filling the openings with a conductive material, such that when the conductive material is applied, any air in the openings moves into the regions of the adhesive layer with less thickness adjacent the openings.

An apparatus has a first structure, an adhesive layer having a first height adhered to the first structure, the adhesive layer having an array of openings, the adhesive layer having a region adjacent each opening having a height less than a first height. A print head has a stack of plates forming a jet stack, the jet stack having a nozzle plate with an array of nozzles, an array of transducers in contact with the jet stack opposite the nozzle plate, an adhesive layer having a first height adhered to the array of transducers, the adhesive layer having openings adjacent the transducers and regions adjacent the openings having a height less than the first height, and a conductive material in the openings of the adhesive layer in contact with the transducers.

A printhead for a printer and methods for making the printhead. The printhead may include a driver module on a jetstack. The jetstack may include a plurality of holes formed therethrough. A first adhesive layer may be disposed on the jetstack. A diaphragm plate may be disposed on the first adhesive layer. A piezoelectric layer may be disposed on the diaphragm plate. A second adhesive layer may be disposed on the piezoelectric layer. A chip on flex may be disposed on the second adhesive layer.

Modular printhead sub-assembly

A flex circuit board provides islands of electrically isolated material surrounding openings in the flex circuit board to preserve fluid integrity of passageways passing through an electrically insulating layer of the flex circuit board. The electrically isolated islands surround exits of the passageways through the electrically insulating material and extend the passageways through an electrically conductive layer of the flex circuit board. Consequently, fluid passing through the passageways and electrically isolated islands in the flex circuit board is not subjected to electrical current.

An electrical interconnect has an adhesive layer in which is formed an array of apertures, the apertures being of non-circular shape. An electrical circuit apparatus has a first circuit having at least one electrical contact, a second circuit having at least one electrical contact aligned to the electrical contact of the first circuit, and a standoff structure between the first and second circuits having at least one aperture aligned to one electrical contact of the first and second circuits, the aperture being of a non-circular shape.

Electrical interconnect with maximized electrical contact

A printing system includes a print head to deliver ink to an image receptor and at least one ink reservoir to deliver ink to the print head. Driving circuitry provides signals to the print head to control delivery of the ink and a flexible circuit interposed between the print head and the ink reservoirs connects the driving circuitry to the print head. The flexible circuit may include a heater to provide heat to the ink reservoirs. Alternatively, the flexible circuit may be replaced with a rigid substrate having a heater within its layers.

A multiple chamber fly trap contains approximately concentric screens defining a region within the inner screen into which the flies enter for the bait, an annular second region between the screens into which the flies enter to escape to the light, and a third region below the second region into which the flies drop after exhaustion. A plurality of openings between the consecutive regions allow passage of the flies from the first to the second to the third and into a removable collector which is preferably a disposable bag.
