を行う。Not only the LED lamp shown in FIG. 3 but also an electronic component having a soldering pin is generally mounted on a substrate by automatic mounting. In automatic mounting, it is necessary to perform a lead clinch for the pins before the solder dipping process. For example, when automatically mounting the LED lamp shown in FIG. 3, first, as shown in FIG. 4, the pins P 1 and P 2 are inserted into the holes H 1 and H 2 formed in the substrate 5, respectively. Then, with an automatic machine, move the pins P 1 and P 2 to the arrows m, respectively.

After the 1 and the pin P 2 are cut to a predetermined length by cutting the D 1 -D 1 line and the D 2 -D 2 line, respectively, solder dipping is performed.

Since mechanical stress is applied to 1 and P 2 during lead clinch, mechanical stress remains. Therefore, when heat is applied to the resin molding 1 by the solder dip, the resin molding 1
Cracks and strains are generated in the resin, and the above-mentioned stress causes the pins P 1 and P 2 to move, resulting in disconnection of the wire 2 in the resin molding 1 (so-called open failure).

This embodiment is characterized in that it is not electrically connected to P 2 internally and externally) and that a pseudo pin P 3 used for lead clinch at the time of board mounting is provided. Other than that, the configuration is the same as that of the conventional example (FIGS. 3 and 4).
The pin P 3 is formed together with the other pins P 1 and P 2 when the lead frame is manufactured by punching a flat plate.

よってオープン不良が生じることもない。As is apparent from FIG. 1, the pin P 3 is only fixed to the resin molded body 1 at one end, and therefore has no involvement in the electrical action. Then, it is used as a dummy pin exclusively for the lead clinch. As shown in FIG. 2, the lead clinch has pins P 1 -P in holes H 1 -H 3 of the substrate 5.
This is done by inserting force on pin P 3 only after inserting P 3 . The solder dip is applied in a state where the pins P 1 and P 2 are simply inserted into the holes H 1 and H 2 of the substrate 5, respectively. Therefore, no stress is generated on the pins P 1 and P 2 which are the polar terminals, and accordingly, no open failure occurs due to heat during solder dipping.

Further, even if the pin P 3 comes into contact with the other pins P 1 and P 2 by the lead clinch, since the pin P 3 is not internally connected to anything as described above, no problem occurs.

It is possible to realize an electronic component in which stress does not occur in the soldering pins and open defects do not occur even if heat is applied during soldering.
