  • Patent number: 8621751
    Abstract: 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.
