Abstract: The present invention discloses an analysis method of a tensioning process of a fine mask plate. The analysis method, based on the simulation function of ANSYS software, finds an appropriate tensile force for stretching a fine mask plate and a corresponding actual counterforce applied to a metal frame before each fine mask plate is welded onto the metal frame through establishing a finite element model of the fine mask plate and a finite element model of the metal frame.. The analysis process requires no physical tests, thereby effectively avoiding damaging the fine mask plate and further effectively saving the test cost.

Abstract: Disclosed are a mask device and a method for assembling the same. The mask device may include a frame; and a mask plate arranged within the frame. The frame may include a first frame and a second frame which are fixed together one on another. The first frame may be made of a shape memory alloy; while the second frame may be made of a metal material whose thermal expansion coefficient is smaller than a predetermined value. And the mask plate is welded to the first frame.
