摘要： The invention relates to an ink jet pen having exposed surfaces which are coated with a polymeric material. The polymeric material is treated with ultraviolet energy at a wavelength and for a period of time sufficient to increase the surface energy of the coating to thereby enhance the adhesive properties of the coating. The coated polymeric material and treated pen exhibits improved corrosion resistance and are more compatible with adhesives used to assemble components of the pen than similar untreated coatings.

摘要： The invention described in the specification relates to an ink jet printhead structure having semiconductor substrate containing energy imparting devices for ejecting ink through nozzle holes in a nozzle plate, 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 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： The invention described in the specification relates to an improved method for making a printhead for an ink jet printer. In the method, one or more semiconductor substrates containing energy imparting devices for ink and electrical conductors for the energy imparting devices are attached to a metal substrate carrier. A conductive layer containing electrical tracing terminating in contact pads is also attached to the carrier using an adhesive. A nozzle plate is attached to the conductive layer and to the semiconductor substrate also using an adhesive. The nozzle plate, conductive layer and adhesive all have openings or windows therein for use in forming wire bonds between the semiconductor substrate and the conductive layer. Once the wire bonds having loops are formed, the wire loops are depressed toward the nozzle plate to reduce the height of the loops above the nozzle plate. The entire wires and bonds are then encapsulated in a elastomeric, insulative material to protect the wires. An advantage of the depressed wire loops is that the encapsulating material layer may be relatively thin so that it does not extend above the exposed surface of the nozzle plate more than about 15 mils thereby providing maximum clearance between the printhead a media to be printed.
摘要翻译：本说明书中描述的本发明涉及一种用于制造用于喷墨打印机的打印头的改进方法。在该方法中，一个或多个含有能量赋予装置的能量赋予装置的半导体基板和能量赋予装置的电导体被附着到金属基板载体上。包含端接在接触垫中的电迹线的导电层也使用粘合剂附着到载体上。喷嘴板也使用粘合剂附着到导电层和半导体衬底上。喷嘴板，导电层和粘合剂都具有用于在半导体衬底和导电层之间形成引线接合的开口或窗口。一旦形成了具有环的线接合，则线圈朝向喷嘴板压下，以减小喷嘴板上方的环的高度。然后将整个电线和接合件封装在弹性体绝缘材料中以保护电线。凹陷的线环的优点在于，封装材料层可以相对较薄，使得其不会在喷嘴板的暴露表面上方超过大约15密耳，从而在打印头之间提供打印头上要打印的介质之间的最大间隙。

摘要： A method of tape automated bonding a heater chip of an ink jet printer to a flexible circuit includes the step of attaching an electrically conductive bonding pad to a first portion of a surface of the heater chip. A mask is applied to a second portion of the surface of the heater chip. An exposed surface of the bonding pad is chemical dry etched for a predetermined time period to thereby remove contaminants from the etched exposed surface. The chemical dry etching is terminated at an end of the predetermined time period such that substantially none of the bonding pad is removed. Lastly, the flexible circuit is electrically connected to the etched exposed surface.

摘要： A printhead comprises a source of ink, a body, a mounting base, and an ink heater thermally coupled to the mounting base. A flowpath delivers ink from the ink source to the heater and is defined at least in part by the mounting base on the body. Three or more thermally conductive paths extend from the mounting base to the body. Preferably, one or more of the thermally conductive paths are heat conductive bridges extending from the mounting base to the body through an edge feed via.

摘要： An ink jet printhead includes a chip layer having a via for receiving ink, and having at least one actuator. A barrier layer is disposed adjacent the chip layer, and forms at least one throat which has a width and a cross-sectional area. The barrier layer also forms at least one bubble chamber, with each throat adapted to receive ink from the via and provide it to the respective bubble chamber. A nozzle layer is disposed adjacent the barrier layer, opposite the chip layer, and forms at least one nozzle for ejecting ink from the respective bubble chamber when the ink is energized by the associated actuator. At least one post is disposed proximate the throat, and extends part way between the chip layer and the nozzle layer. The post forms one or more gates through which the ink must pass from the via to the at least one throat.
