20120055022METHOD OF PRODUCING LIQUID EJECTION HEAD - The present invention provides a method of producing a liquid ejection head, the method including the steps of preparing a substrate having a flow-path-wall member; bonding the flow-path-wall member to a resin layer that is composed of a photo-curing resin and serves as an ejection port member such that spaces serving as the flow paths are provided inside; providing through-holes in the resin layer such that the spaces communicate with the outside air; exposing part of the resin layer; heating the exposed portion of the resin layer; and removing the unexposed portion from the heated resin layer to form the ejection ports, thereby forming the ejection port member in the resin layer.03-08-2012
20120055021INKJET HEAD MANUFACTURING METHOD - An inkjet head manufacturing method includes the following steps. Firstly, a multilayered structure with a plurality of microstructure layers is provided. The alignment check holes of the microstructure layers are concentric and have different diameters. Then, the microstructure layers are stacked together and the microstructure layers are aligned with each other according to the concentric and different-diameter alignment check holes, wherein a dry film layer is sandwiched between every two adjacent microstructure layers. The preset slots of the microstructure layers are collectively defined as inlet flow channels, ink chambers, pressure cavities and outlet flow channels. Then, the multilayered structure is assembled and positioned through the dry film layers by a thermal compression process. Then, a cutting knife is used to linearly cut the actuator plate over a spacer between every two adjacent pressure cavities and along a path parallel with rims of the pressure cavities.03-08-2012
