Problems solved by technology
However, when the thickness of the vapor deposition mask is reduced, when the vapor deposition mask is stretched and supported on a frame, warping or waviness may sometimes occur in the vapor deposition mask
Therefore, the close adhesion between the vapor deposition mask and the frame is reduced, and welding failure occurs in the non-adherent portion of the vapor deposition mask and the frame. Therefore, it is considered that the strength of the welded portion of the vapor deposition mask cannot be sufficiently ensured.
Especially in the case where the thickness of the evaporation mask is small, the strength of this solder joint may become a problem

Abstract
A method for manufacturing a vapor deposition mask device and a manufacturing device for a vapor deposition mask device. The manufacturing method of the evaporation mask device has: a preparatory step of preparing an evaporation mask including a plurality of through holes from a first surface to a second surface; Solder evaporation mask on the front side.
Description
technical field [0001] One embodiment of the present disclosure relates to a manufacturing method of a vapor deposition mask device having a vapor deposition mask formed with a plurality of through holes and a frame supporting the vapor deposition mask, and a manufacturing device of the vapor deposition mask device. Background technique [0002] In recent years, display devices used in portable devices such as smartphones and tablet PCs have required high definition, for example, a pixel density of 500 ppi or more. In addition, in portable devices, there is an increasing need to support ultra-full high-definition, and in this case, the pixel density of the display device is required to be, for example, 800 ppi or higher. [0003] Among display devices, organic EL display devices have attracted attention because of their excellent responsiveness, low power consumption, and high contrast. As a method of forming pixels of an organic EL display device, a method of forming pixel...
