摘要： A method of manufacturing a nozzle for an inkjet head is disclosed. With the method of manufacturing a nozzle for an inkjet head, comprising (a) coating photoresist on an inkjet head structure comprising a nozzle part; (b) adjusting exposure conditions and performing exposure and developing on the nozzle part to remove a portion of the photoresist; (c) joining a hydrophobic layer onto the portion of the nozzle part where the photoresist has been removed; and (d) removing the photoresist remaining on the nozzle part, it is easy to control the depth of the hydrophobic layer to be uniform, and the depth to which the hydrophobic layer is deposited may be controlled even when the back surface of the nozzle has a complex shape, so that the uniformity and reproduction of the hydrophobicity-treated nozzles are improved.

摘要： A manufacturing method of a nozzle for an inkjet head. With the nozzle for an inkjet head, including a first board in which a nozzle hole is perforated, a middle layer stacked on the first board and perforated in an area corresponding to the nozzle hole, and a second board stacked on the middle layer and perforated in an area corresponding to the nozzle hole, where a hydrophobic layer is joined onto the inner perimeter of the nozzle hole and onto the first board around the nozzle hole, the uniformity and reproduction quality may be improved of nozzles treated for hydrophobicity, as the depth of the hydrophobic layer may be controlled to be uniform and the deposition of the hydrophobic layer may be prevented at the back surface of the nozzles.
