Patent ID: 10350892

Abstract:
A manufacturing method of a fluid control device is provided. Firstly, a housing, a piezoelectric actuator and a deformable substrate are provided. The piezoelectric actuator includes a piezoelectric element and a vibration plate having a bulge. The deformable substrate includes a communication plate and a flexible plate having a movable part. Then, the flexible plate and the communication plate are stacked and coupled. A preformed synchronous deformation process is implemented by applying at least one external force to outer portion of the deformable substrate to form a preformed synchronously-deformed structure. A force-exerting mark is formed on a surface of the preformed synchronously-deformed structure. Then, the housing, the piezoelectric actuator and the deformable substrate are sequentially stacked and coupled. The preformed synchronously-deformed structure is aligned with the bulge of the vibration plate. A specified depth is defined between the movable part and the bulge of the vibration plate.
