摘要： PROBLEM TO BE SOLVED: To provide a printing head reduced in thermal and mechanical stress and a method for producing the same. SOLUTION: In a method for producing an ink jet printing head by bonding a nozzle plate to a polymer layer by heat, the polymer layer 22 is arranged between a semiconductor substrate and the nozzle plate and includes an expanding gap space or trough part sufficient to suppress the stress in a structure during the process bonding the nozzle plate 26 to the polymer layer 22. By this constitution, the problem of the positional shift and strain caused by a conventional head structure is reduced.

摘要： PROBLEM TO BE SOLVED: To eliminate an additional process for alignment and removal of an adhesive, by coating a composite strip including a polymeric material with a polymeric sacrifice layer, effecting resorption to a nozzle hole, etc., in the composite strip by a laser, and removing the sacrifice layer. SOLUTION: A composite strip 26 is moved along nozzle plates 150 by sprocket holes 88 arranged adjacently to confronting edge parts 89 of the composite strip 26 at the opposite side to the nozzle plates 150. The nozzle plates 150 are divided to be individual plates by ablation by a laser through a sacrifice layer, an adhesive layer and a polymeric material to form a plurality of slits 92 as rectangular patterns in the periphery of the nozzle plates 150. The slits 92 in the periphery of the nozzle plates 150 are defined by a projecting mask. A laser light is passed through a hole in the projecting mask and does not reach the composite strip 26 through the other part of the mask.

摘要： A nozzle plate for an ink jet print head which is coated with a low surface energy polymer with the attaching surface further coated by tantalum in a thickness range of 50 to 500 Angstroms. The tantalum gives excellent attachment over a wide range of environments.
A master sheet of individual nozzle plates is first coated by chemical vapor deposition and then sputter coated with tantalum on the attachment side. These are quite inexpensive and avoid the use of a more expensive gold coating.

摘要： A print head having an ink reservoir (66) therein is made by forming, in a one-shot plastic injection molding step, a rigid monolithic frame (50) comprising high melt temperature material having an opening (56) therein extending from a first side (58) to a second side (59), and first and second bonding surfaces (68,69) surrounding the opening and facing the first and second sides, respectively. First and second thin flexible films (52',52) are adhesively secured to the first and second bonding surfaces, respectively. The adhesive material may be a hot melt adhesive or dry adhesive films pre-formed to the shape of the bonding surfaces. By securing the flexible films to the bonding surfaces adhesively, rather than by heat staking, it is not necessary to form the frame of different materials during two separate molding steps.
摘要翻译：在其中具有墨水储存器（66）的打印头通过在单次注射成型步骤中形成由包括高熔体材料的刚性整体框架（50）制成，所述刚性整体框架（50）具有从第一侧延伸的开口（56）（58）到第二侧（59），以及分别围绕开口并面向第一和第二侧的第一和第二接合表面（68,69）。第一和第二薄柔性膜（52'，52）分别粘合地固定到第一和第二粘合表面。粘合剂材料可以是预先形成为粘合表面形状的热熔粘合剂或干燥粘合剂膜。通过将柔性膜固定到接合表面上而不是通过热铆接，在两个分开的模制步骤期间不需要形成不同材料的框架。

摘要： The invention described in the specification relates to an ink jet printhead structure having semiconductor substrate (12) containing energy imparting devices for ejecting ink through nozzle holes in a nozzle plate (26), to a method for making a printhead structure and to a printer cartridge containing the printhead structure. In order to reduce stresses induced in the structure during manufacturing and/or use thereof, a polymeric layer (22) is disposed between the semiconductor substrate and nozzle plate which contains expansion void spaces or valleys sufficient to inhibit stresses in the structure during a process for bonding the nozzle plate to the polymeric layer thereby reducing misalignment and warpage problems associated with conventional printhead structures.

摘要： A method for making an inkjet printhead nozzle plate from a composite strip containing a nozzle layer (10) and an adhesive layer (24) is disclosed. The adhesive layer (24) is coated with a polymeric sacrificial layer (28) prior to laser ablating the flow features (16,18,20) in the composite strip. A method is also provided form improving adhesion between the adhesive layer (24) and the sacrificial layer (28). Once the composite strip containing the sacrificial layer (28) is prepared, the coated composite strip is then laser abated to form flow features (16,18,20) in the strip in order to form the nozzle plates. After forming the flow features, the sacrificial layer (28) is removed. Individual inkjet printhead nozzle plates are separated from the composite strip by singulating the nozzle plates with a laser.
