Abstract
Provided is a method of manufacturing a deposition mask frame assembly, the method including placing and welding a support stick mask and a gap stick mask on a frame, and joining edges of a deposition stick mask with the frame by welding while the deposition stick mask is tensioned in a longitudinal direction of the X-axis direction and at the same time, adhesively tensioned in the Y-axis direction, thereby preventing wrinkles due to the tensioning of the deposition stick mask to manufacture a fine and high-quality deposition mask frame assembly.
Claims6
A method of manufacturing a deposition mask frame assembly using a deposition stick mask that includes a structural stick mask with edges and ribs and cell unit masks with deposition pattern holes, the method comprising:
- preparing a frame having a quadrangular shape with a central opening;
- placing and welding a support stick mask on a frame while the support stick mask is tensioned in a longitudinal direction of a Y-axis direction;
- placing and welding a gap stick mask on the frame while the gap stick mask is tensioned in a longitudinal direction of an X-axis direction;
- and
- placing the deposition stick mask on the frame, and welding the edges on the frame while the deposition stick mask is tensioned in a longitudinal direction of the X-axis direction and at the same time, adhesively tensioned in the Y-axis direction,
- wherein the gap stick mask is fixed on the support stick mask by welding overlapping regions of the gap stick mask and the support stick mask, and
- the ribs are located on the support stick mask and the edges are located on the frame or the gap stick mask, and both of which function as welding zones.
