    摘要： Process for protectively coating against aggressive liquids hydraulic microcircuits made in a resin (32), particularly for an ink jet printhead, consisting of: a9 disposing of a silicon substrate (20) comprising a sacrificial layer (26) of copper, deposited on the substrate and defining the inner shape of the hydraulic microcircuits (35, 36, 37); b) depositing on top of the outer surface of the sacrificial layer (26), by means of an electrochemical process, at least one protective, metallic coating layer (30); c) applying on the sacrificial layer (26) a non-photosensitive epoxy or polyamide resin (32), having a predetermined thickness and suitable for completely covering the sacrificial layer (26); d) effecting a polymerization of the resin (32) to increase its mechanical resistance to mechanical and thermal stresses and performing a planarization of the outer surface (33) of the resin (32), by means of a mechanical lapping and simultaneous chemical treatment; e) removing the sacrificial layer (26) through a chemical etching, in a highly acid bath; f) depositing a metallic, protective layer (39) on the outer surface (33) of the resin (32), through vacuum evaporation.

    摘要： A method of producing an ink-jet head having an ink chamber composed of at least a first wall member and a second wall member, wherein the first wall member includes a vibrating wall made of a piezoelectric ceramic on which an electrode layer is formed and the second wall member forms a fixed wall, comprising steps of: (1) combining the first wall member and the second wall member into one body so that the ink chamber is formed between the first wall member and the second wall member and the electrode layer is located inside the ink chamber; and (2) subjecting the combined one body of the first wall member and the second wall member to gas phase polymerization so that a resin layer of poly-para xylylene or its derivative is formed on the electrode layer in the ink chamber.
