A method for producing a plasma display panel includes: (i) providing a front panel and a rear panel, the front panel being a panel wherein an electrode A, a dielectric layer A and a protective layer are formed on a substrate A, and the rear panel being a panel wherein an electrode B, a dielectric layer B, a barrier rib and a phosphor layer are formed on a substrate B; (ii) supplying a glass frit material onto a peripheral region of the substrate A or B to form a glass frit sealing member; (iii) opposing the front and rear panels with each other such that the glass frit sealing member is interposed therebetween; and (iv) heating the opposed front and rear panels to reach a softening point of the glass frit sealing member or a higher temperature than the softening point, while supplying a cleaning gas into a space formed between the opposed front and rear panels. Prior to the heating of step (iv), a gas is introduced into a space formed between the opposed front and rear panels, or a gas is exhausted from a space formed between the opposed front and rear panels.

A multilayered board data input unit inputs design data of a multilayered circuit board provided with through holes penetrating and mutually connecting solid-layer conductors disposed in a multilayer manner. A limitation rule setting unit sets a limitation rule for limiting the number of solid-layer conductors to be connected to the through holes. A separation processing unit separates connections of the solid-layer conductors to the through holes in the design data based on the limitation rule. At this time, when a solid-layer conductor to be separated from the through holes is selected as a candidate, the separation processing unit determines whether the solid-layer conductor is isolated by separation, when the solid-layer conductor is not isolated, determines isolation, and when the solid-layer conductor is isolated, stops separation.

A matrix switch board used for connecting and disconnecting a switching-system line and a subscriber line. The matrix switch board includes a board made of an insulating material, and first and second wiring patterns respectively formed on front and back sides of the board so as to cross each other. The matrix switch board further includes through holes provided at cross points of the first and second wiring patterns. In the matrix switch board, when a connection pin is inserted into at least one of the through holes, at least one of the first wiring patterns on the front side and at least one of the second wiring patterns on the back side are electrically connected to each other.

A front plate and a back plate are superposed with each other in parallel, and pressed onto each other. Moreover, the back plate and a gas-blowing jig are brought into close contact with each other. The glass pipe in which a glass fiber filter paper is placed is pressed onto the back plate, with a solid-state glass frit ring interposed therebetween. Thus, by using a glass pipe, a nitrogen, Xe, or Ne gas is supplied into the panel, or the inside of the panel is evacuated.

A circuit board packaging structure comprises a plurality of circuit boards disposed in parallel to each other and each packaged with electric circuit parts. The circuit board packaged with electric circuit parts exhibiting a larger exothermic quantity than those of the electric circuit parts packaged on the other circuit boards is disposed outermost among the plurality of circuit boards. The surface of the circuit board packed with the electric circuit parts exhibiting the larger exothermic quantity is directed outside the structure.
