Mask frame welding jig and method of using same

Abstract

A method and apparatus for attaching a tension mask to a mask frame. The apparatus is comprised of a clamping plate upon which is mounted a frame clamp and a frame deflector assembly. Above the clamping plate is located a mask clamp assembly comprising a forming slide. A mask frame is inserted into the frame clamp and secured on a plurality of axes to the top of the clamping plate. As the mask frame is secured, a compression force is applied to the mask frame by the frame deflector assembly and a tension mask is aligned and positioned to the top of the mask frame. While the mask frame is in compression, a forming edge on the forming slide conforms an edge of the tension mask to the mask frame where it is then affixed. The compression force on the mask frame is then released causing the frame to impart a tension force on the tension mask.
