摘要： A method for assembling a printhead such as an ink jet printhead can include the use of an ultrasonic bonding process to bond two or more printhead layers together. In an embodiment, an ultrasonic frequency is directed to an interface between a first layer and a second layer to generate heat at the interface. In an embodiment, the heat melts at least one of the first layer and the second layer, and the layers are cooled to cure the melted layer. In another embodiment, the heat generated using the ultrasonic frequency cures an adhesive layer between the first layer and the second layer. The ultrasonic lamination process described can result in a fluid-tight seal which requires less processing time and materials over an adhesive-based process.

摘要： A large array or pagewidth printhead fabricated from printhead elements or subunits. The printhead subunits are butted together at either adjacent channel elements or adjacent heater elements to form a pagewidth printhead. The butting element, either heater or channel element, is slightly wider than the non-butting element thereby providing gaps between the non-butting elements of a printhead element array. Where channel elements are used as the butting element, gaps between the heater elements provide for reduction or elimination of potentially damaging thermal compressive forces between adjacent heater elements. Where heater elements are used as the butting element, structural strength is increased since the heater wafer is stronger than the channel wafer. In addition, the width of the polyimide wall at the edges of the heater wafer is increased providing greater protection for thermal transducers located at the edges of individual heater elements.
摘要翻译：由打印头元件或子单元制造的大阵列或页宽打印头。打印头子单元在相邻的通道元件或相邻的加热器元件对接在一起以形成页宽打印头。对接元件（加热器或通道元件）比非对接元件稍宽，从而在打印头元件阵列的非对接元件之间提供间隙。在使用通道元件作为对接元件的情况下，加热器元件之间的间隙用于减少或消除相邻加热器元件之间潜在的有害的热压缩力。当加热器元件用作对接元件时，由于加热器晶片比通道晶片更强，所以结构强度增加。此外，加热器晶片边缘处的聚酰亚胺壁的宽度增加，为位于各个加热器元件边缘的热传感器提供更大的保护。

摘要： A method for forming an ink jet print head can include attaching a plurality of piezoelectric elements to a diaphragm of a jet stack subassembly, electrically attaching a flex circuit to the plurality of piezoelectric elements, then dispensing an dielectric underfill between the flex circuit and the jet stack subassembly. The use of an underfill after attachment of the flex circuit eliminates the need for the patterned removal of an interstitial material from the tops of the piezoelectric elements, and removes the requirement for a patterned standoff layer. In an embodiment, electrical contact between the flex circuit and the piezoelectric elements is established through physical contact between bump electrodes of the flex circuit and the piezoelectric elements, without the use of a separate conductor, thereby eliminating the possibility of electrical shorts caused by misapplication of a conductor.

摘要： A method and structure for forming an ink jet print head having a dielectric interstitial layer. A flexible top plate attached to a press can be used to apply pressure to an uncured dielectric interstitial layer. The uncured dielectric interstitial layer is cured while contacting the uncured dielectric interstitial layer with the flexible top plate and applying pressure using the press. Using a flexible top plate rather than a rigid top plate has been found to form a cured interstitial layer over an array of piezoelectric elements which has a more uniform or planar upper surface. An interstitial layer so formed can result in decreased processing time, reduced problems with ink communication in the ink jet print head during use, and decreased manufacturing costs.
