いった問題点も有していた。However, in the above-mentioned prior art, when the solder is wet on the opposing surfaces of the opposing soldering terminals 1 and 2, it is necessary to check the wetting condition of the solder. The wetting condition of the solder and the terminals 1 and 2
The soldering operation must be performed by observing the degree of solder wetting of the small portion of the side surface of the terminal. Therefore, the determination of the wetting state of the solder on the opposing surfaces of the soldering terminals 1 and 2 is uncertain. Therefore, as a soldering operation, it is necessary to lengthen the heating time,
Since a large amount of solder and flux is used, there is a problem that a long working time is required and a large amount of solder material is used. Further, in order to judge the solder quality of the soldered product, it is necessary to judge the soldering appearance of a minute portion on the side surfaces of the terminals 1 and 2, and therefore, it is difficult to judge, and the judgment is lacking in reliability. There was also a problem that it took time.

る。FIG. 1 is a perspective view of a main part of an embodiment of the present invention. Opposite terminals 1 and 2 are soldered by solder 3. FIG. 2 is a sectional view taken along the line AA 'of FIG. As shown in FIG. 4, the terminal 1 has a shape in which a central portion is narrowed,
That is, it has a drum shape, and has an overhang structure in which the base film 7 is not provided at the soldering terminal portion.
Since the terminal 1 is in the shape of a drum, the degree of solder wetting of the terminals 1 and 2 is not limited to the degree of wetting of the solder on the minute portions of the side surfaces of the terminals 1 and 2, Since the soldering state can be easily determined by observing the degree of wetting of the solder at the portion where the center is thinner and the shape of the solder 3 with the skirt thereof cut, the soldering work is facilitated and the working time is shortened. You. Also, the reliability of soldering,
The quality level is improved and inspection time is reduced. Another advantage of the drum shape of the terminal 1 is that the terminal width is gradually narrowed from both sides toward the center, so that the strength of the terminal after soldering is straight with the terminal width on both sides. And almost the same strength as the conventional terminal. Therefore, even in the case of soldering terminals with a finer pitch, sufficient soldering strength is secured, and soldering work is easy, can be performed in a short time, and soldering with sufficient soldering quality is possible It is.

である。FIG. 5 is a perspective view of a main part of another embodiment of the present invention of the flexible substrate of FIG.
Is similar to the shape of the terminal in FIG. 4, but the base film 7 has the same shape as the terminal 1 up to the soldering terminal portion. That is, since the terminal width of the central portion of the soldered terminal is narrow, when soldering, the solder is wet not only on the side surface of the terminal but also on the narrow portion of the central portion, similarly to the embodiment of FIG. The soldering state can be easily determined by observing the state where the bottom of the solder is pulled. Therefore, the soldering operation becomes easy and the operation time is shortened. In addition, the reliability and quality level of soldering are improved, and the inspection work time is shortened. Further, it is also effective as a fine pitch soldering terminal as in the embodiment of FIG.
