Abstract
A transition section for relieving temperature difference between a fore and a back of a substrate is provided before a temperature section at which constituent elements are fired. As a result, a method of manufacturing a plasma display panel and a firing apparatus, where the temperature difference between the fore and the back of the substrate in a substrate-moving direction is prevented and the constituent elements are fired well, can be provided.
Claims8
A method of manufacturing a plasma display panel (PDP) for heating a substrate while conveying the substrate, the method comprising:
- a heating step for heating the substrate to a first temperature T1 (° C.) with a first temperature gradient;
- a transition step for heating the substrate from the first temperature T1 (° C.) with a second temperature gradient smaller than the first temperature gradient;
- and
- a temperature keeping step for keeping temperature for a predetermined period at a second temperature T2 (° C.) higher than the first temperature T1 (° C.).
A firing apparatus for a plasma display panel (PDP) including a conveyer for conveying a substrate and a firing unit for firing the substrate which is conveyed by the conveyer, the firing apparatus comprising:
- a temperature pattern for firing the substrate including:
- a temperature rising section for heating the substrate to a first temperature T1 (° C.) with a first temperature gradient;
- a transition section for heating the substrate from the first temperature T1 (° C.) with a second temperature gradient smaller than the first temperature gradient;
- and
- a temperature keeping section for keeping temperature for a predetermined period at a second temperature T2 (° C.) higher than the first temperature T1 (° C.).
