Abstract

In conventional plasma display fabrication, the final step in a glass sealing operation involving the front and rear glass substrates occurs. The sealing operation involves the positioning of four seal rods between the two substrates and locating them in a seal fixture; also included is the positioning of the glass tubulator as well as it's seal donut. This assembly is then placed on the belt of an in-line furnace. As the fixture travels through the furnace, the temperature is elevated above the reflow temperature of the glass seal rods (438ŒC). This in turn causes the upper substrate to be forced downward by the fixture's mass until it contacts the nickel spacers which define the chamber gap, i.e., the separation between the two substrates.
