Abstract

PURPOSE:To prevent the generation of a spark by heating and clamping a conductor formed in a ladder pattern between a substrate and a sheet of fluororesin in manufacture of a microstrip line used for a microwave heating device. CONSTITUTION:The figure shows an oblique sketch of a disassembled microstrip line. The conductor 3 has slits 10- punched by a press, etc., to obtain an earth conductor having the ladder pattern 7. Further, 2 is a dielectric substrate made of polytetrafluoroethylene as well as a conventional substrate and 4 is a center conductor. A member 11 is an upper sheet made of polytetrafluoroethylene to be press-contacted thermally with the earth conductor 3, and 12 is a lower sheet of polytetrafluoroethylene to be press-contacted thermally with the reverse surface of the center conductor 4. The lower sheet 2, center conductor 4, substrate 2, earth conductor 3, and upper sheet 11 are laminated in order and press-contacted thermally from below and above to manufacture the microstrip line.

The top may be coated with an insulating material (for example,
1855-178333), it has been proposed to attach a cover (for example, Japanese Patent Application No. 56-41087). However, simply coating the ladder pattern (7) with an insulating material causes it to peel off easily, and it is also difficult to attach the cover onto the ladder pattern (7) in a glittering manner.

Also, since the slits in the ground conductor (3) were formed by etching, the edges were cut into the board (2), making sparks more likely to occur. Therefore, proposals for removing this edge part (for example, Japanese Patent Application No. 56-16
7459> has been done. However, in order to remove this edge portion, a dedicated device is required and the number of production steps increases.The present invention was made in view of the drawbacks of the conventional example.
The f7J method of microstrip line is characterized in that a rod on which a ladder pattern is formed is heated and pressed between a substrate and a sheet made of fluororesin.

As mentioned above, according to the present invention, the conductor on which the ladder pattern is formed is covered with glitter by the substrate and sheet made of fluororesin, so there is no chance of sparks being generated. Furthermore, since the conductor is not formed by conductor row-to-conductor cutting, no edge portion of the conductor remains on the substrate, and four steps are required to remove the edge portion.
