Abstract: A mask frame assembly with alignment marks in both a frame and a mask plate and an evaporation apparatus are disclosed. The mask frame assembly comprises a frame and a mask plate fixed on the frame. The mask frame assembly is provided with alignment marks, which comprise a first alignment hole arranged in the frame and a second alignment hole arranged in the mask plate. The first alignment hole is a through hole. The mask frame assembly effectively solves a problem in which liquid residuals in alignment holes of the frame interfere with alignment.

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.
