HEATING APPARATUS FOR MANUFACTURING OF PLASMA DISPLAY PANEL

摘要

A heat treatment apparatus used to manufacture a plasma display panel is provided to perform a heat treatment of a substrate at an optimum state by precisely controlling a transfer speed of the substrate and intensity of light. A heat treatment apparatus includes a transfer unit(604) transferring a substrate, and a focusing light irradiating unit(606) irradiating light onto the substrate. The focusing light irradiating unit controls intensity of the light according to a profile of firing temperature set for each firing step. The transfer unit controls a transfer speed of the substrate according to the profile of firing temperature set for each firing step.
