    • A method is described for uniformly coating portions of the surface of a substrate which is to be bonded to another substrate. In a described embodiment, the two substrates are channel plates and heater plates which, when bonded together, form a thermal ink jet printhead. The adhesive layer is electrophoretically deposited over a conductive pattern which has been formed on the binding substrate surface. The conductive pattern forms an electrode and is placed in an electrophoretic bath comprising a colloidal emulsion of a preselected polymer adhesive. The other electrode is a metal container in which the solution is placed or a conductive mesh placed within the container. The electrodes are connected across a voltage source and a field is applied. The substrate is placed in contact with the solution, and a small current flow is carefully controlled to create an extremely uniform thin deposition of charged adhesive micelles on the surface of the conductive pattern. The substrate is then removed and can be bonded to a second substrate and cured.
    • 描述了用于均匀地涂覆待结合到另一基板的基板的表面的一部分的方法。 在所描述的实施例中,两个基板是通道板和加热板,当它们结合在一起时形成热喷墨打印头。 粘合剂层被电泳沉积在已经形成在粘合衬底表面上的导电图案上。 导电图案形成电极并且放置在包含预选聚合物粘合剂的胶体乳液的电泳浴中。 另一个电极是其中放置溶液的金属容器或放置在容器内的导电网。 电极通过电压源连接,施加场。 将基板放置成与溶液接触,并小心地控制小电流,以在导电图案的表面上产生电荷粘合胶束的非常均匀的薄沉积。 然后去除衬底并且可以结合到第二衬底并固化。
