摘要： A method of forming a component for a droplet deposition apparatus,includes the steps of: providing a protection material so as to fill fluid chambers and; directing a high-powered laser at the component so as to ablate an array of nozzles communicating with respective filter chambers. The protection material acts to inhibit damage to the walls of the chamber during ablation, such as damage to the interior passivation coating, or electrodes provided on the walls of the chamber, and can be removed for example by flushing with a heated solvent.

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 printhead assembly comprising the printhead and filters intended for use with the printhead is passivated by passing a gaseous coating such as Parylene through the assembly. In this way dirt particles created during manufacture of the printhead are encapsulated and thus prevented from blocking the nozzles. The printhead assembly is also prevented from interacting physically or chemically with ink flowing through the printhead.

摘要： Since the same water-repellent process is provided on the nozzle forming part and the outer circumferential part of the nozzle formation member, same process as for the nozzle forming part is needed for the outer circumferential part which is not limited for its structural demand thereby the manufacturing process is complicated and needs high cost. The first water-repellent layer 41 due to the first water-repellent process is formed on the surface of the nozzle forming part 31 formed the nozzle 4 of the surface of the nozzle plate 2, and the second water-repellent layer 42 due to the second water-repellent process different from the first water-repellent process is formed on the surface of the outer circumferential part (outer portion of surface) of the nozzle plate 2. Materials and processes, in which the second water- repellent layer can be formed using simple manufacturing process, can be selected for the second water-repellent process.
