CONSTITUTION: A screen mask comprises a mesh adhered and mounted with a predetermined pressure at an upper surface(2a) of a frame(2) formed with a center bar, and a bend surface(4) bent to an inner surface extended from the upper surface of the frame. A width of an inner surface in the frame is larger than an outer surface(2b). A radius of a winding angle in the winding surface is formed with 50mm and a radius of a corner side is formed with a winding surface of 2mm. |
