It was in a state that easily occurred. Since the base material such as iron is exposed in the cross section after the tie bar is cut, soldering defects such as repelling during solder plating are likely to occur.

することができる。FIG. 1 is a front view of a lead frame according to the present invention. The lead frame 1 is formed by integrally molding the leads 2, 2 ′, the tie bar 3, and the outer frame 5. Tie bar 3 is orthogonal to leads 2 and 2 ', and
The tie-bars 3 are alternately shifted between the adjacent leads 2 and 2 ′ so that the connecting section 4 does not have two or more places in the plane section. As described above, the connection portion of the tie bar, which has conventionally existed at two places on one flat section of each lead, is changed to one place on one flat section of each lead in the present invention, so that the solder has good adaptability and the wraparound. This makes it easier to prevent poor soldering.

きる。Next, an embodiment of a lead frame provided with a tie bar having another shape will be described. FIG. 2 shows a front view of another lead frame of the present invention. Lead 2,
The lead frame 1 is formed by integrally molding the 2 ′, the hatched tie bar 3 and the outer frame 5. In this way, even if the leads 2, 2 '... Are connected by the oblique tie bar 3, the tie bar 3 can be arranged so that the connecting portion 4 does not have more than two places in one flat section of each lead. In addition, the solder has good adaptability and is easy to turn around, so that poor soldering can be prevented.

で、できるだけ小さくするのがよい。In FIGS. 1 and 2, the larger the cross-sectional area of the joint 4 is, the worse the wraparound of the solder during solder plating becomes and the more likely the solder is to be repelled. It is preferable to make the size as small as possible as long as deformation of 2, 2 'can be prevented.

The LED element 7 is mounted on the upper end of the lead 2, the terminal of the LED element 7 is connected to the lead 2 ′ with the thin metal wire 8, and the entire LED element 7 and the thin metal wire 8 and a part of the lead 2, 2 ′ The LED device 10 is sealed with a transparent resin 9 so as to cover the LED device 10. Here, the lead frame shown in FIG. 1 is used. The leads 2 and 2 'have a joint 4 which is a trace of a cross section obtained by cutting a tie bar.
Usually, the burrs remain after the tie bar cut, so that the joint portion 4 can be confirmed.

る。The method of manufacturing the LED device 10 is the same as the conventional one, and includes a tie bar cutting and a solder plating process. After the tie bar cut, the cross section of the joint portion 4 exposes the base material such as iron, so that there is a possibility that soldering failure such as solder repelling may occur at the time of solder plating. However, since the position of the tie bar 3 is shifted so that the connecting portion 4 of the tie bar 3 does not have two or more places in one plane section of each lead, two connecting portions 4 are possessed in one plane section of each lead. Compared with the conventional, the solder familiarity is better,
It becomes easy to go around and it is possible to prevent poor soldering.

The positions of the tie bars are shifted so that there are no more than two tie bar joints in one plane cross section of each lead, so that the solder has good conformability during solder plating, easily turns around, and prevents poor soldering. Can be. Further, by increasing the cross-sectional area of the joint of the tie bars or by providing a plurality of tie bars between the leads to the extent that solder repelling does not occur, a lead frame maintaining the conventional strength can be obtained.
