ABSTRACT:
A process is disclosed for securing a foil mask support structure to the flat glass faceplate of a color cathode ray tube. The frame-like support structure has a base portion adapted for physically penetrating the glass of the faceplate. At least the surface of the faceplate is heated to a predetermined temperature at which it is conditioned to be penetrated by the support structure. The structure is pressed into faceplate, causing the base portion to penetrate to a depth effective both to secure the structure to the faceplate against the tensile forces imparted by the mask, and position the mask mounting surface at a predetermined distance from the faceplate inner surface.
