Abstract:
1. An inkjet head manufacturing method, comprising steps: (a) providing a multilayered structure with a plurality of microstructure layers, wherein a plurality of slots and a plurality of alignment check holes are formed in each microstructure layer, wherein said alignment check holes of said microstructure layers are concentric and have different diameters; (b) stacking said microstructure layers together and aligning said microstructure layers with each other according to said concentric and different-diameter alignment check holes, wherein a dry film layer is sandwiched between every two adjacent microstructure layers, wherein said preset slots of said microstructure layers are collectively defined as inlet flow channels, ink chambers, pressure cavities and outlet flow channels, wherein said pressure cavities are symmetrical and parallel with each other; (c) fixing said aligned multilayered structure by a heating jig, and assembling and positioning said multilayered structure through said dry film layers by a thermal compression process; (d) attaching an actuator plate on said multilayered structure at positions corresponding to said symmetrical and parallel pressure cavities, and using a cutting knife to linearly cut said actuator plate over a spacer between every two adjacent pressure cavities and along a path parallel with rims of said pressure cavities, thereby producing an inkjet head with a plurality of symmetrical inkjet units.
