Abstract

PURPOSE:To improve the turning-around property of solder to a large extent and to eliminate poor soldering by forming a solder well whose groove width is made larger than other parts at the specified part on the side of a lead through hole at each lead containing groove. CONSTITUTION:Lead containing grooves 13 which are deeper than the plate thickness of each end part 2a of a lead are provided in the bottom surface of a stage 10 so that the grooves are communicated to both lead through holes 12 from the facing sides. A solder well 13a which has the wide width at a a position on the side of each through hole is provided in the containing groove 13. A groove part 13b on the side of side edge of the stage 10 has the width so that an excessive gap is not formed between the groove part and the end part 2a of each lead. The groove part 13b is formed in an arc shape around each through hole 12. A rib 15 which acts as a supporting point when the lead is bent and has a specified height is formed on the bending side of the lead at the through hole 12. The rib 15 has an angle so that the rib 15 intersects the extending direction of the end part 2a of the lead at a right angle. The width of the rib 15 is narrower than the width of the containing groove 13. Therefore, the turning-around of solder for the end part of the lead is not hampered, and backlash does not occur between the main body of a capacitor and the stage.

A capacitor made into a chip was obtained as described in 1 above, and FIG. That is,
Apply cream solder to a thickness of about 200μ, for example, on the solder lands 9a, 9a formed on the same substrate 9,
After placing the capacitor on the substrate 9 so that the respective ends 2a, 2a of the leads overlap, the capacitor is heated in a predetermined temperature atmosphere, so that the respective ends 2a, 2a of the leads correspond to each other. It is soldered to the solder lands 9a, 9a.

However, in the above conventional example, the capacitor body 5
In order to prevent relative rotation (so-called wobbling) between the reed and the pedestal 6, the width of the reed storage groove 8 is made slightly wider than the width of the end 2a of the reed, leaving an extra gap between them. Therefore, when mounting on the solder lands 9a, 9a, the cream solder does not wrap around well and cannot be placed stably.Furthermore, the amount of cream solder adhering to each end 2a, 2a of the lead is small and the solder The problem with this method was that it caused defects.

Furthermore, since the lead 2 has elasticity, its end 2a
When the lead is bent and placed in the lead storage groove 8, a so-called springback occurs, as illustrated in FIG. 1O.
There is a problem in that the end portion 2a returns to an angle smaller than the actual bending angle.

Since a part of a protrudes from the groove 8, when mounting it on the board,
The whole thing wobbles and lacks stability. On the other hand, if the latter depth is greater, the end 2a will sink into the groove 8, making soldering difficult.

In order to solve the above problems, in the present invention, a solder pool is formed in a predetermined portion of the lead storage groove of the pedestal on the lead through hole side, the groove width being larger than other portions, and a solder pool is formed in the lead storage groove of the pedestal. A rib having a predetermined height is formed on the bent side edge with a width smaller than the width of the lead storage groove at that portion.

In addition, the above problem was solved by forming a rib with a predetermined protrusion on the side edge of the lead bending side of the lead through hole drilled in the pedestal, and at the same time forming a rib with a predetermined protrusion on the bottom of the pedestal when mounting on the board. This problem can also be solved by providing a taper that makes the central portion on the lead storage groove side float above the substrate surface by contacting the substrate surface as a leg portion.

According to the first configuration, since the solder enters the solder pool, soldering is performed reliably. Furthermore, when bending the end of the lead, by using the rib as a fulcrum and bending it at a larger angle in anticipation of its springback, the end can be properly accommodated in the lead storage groove. In this case, since the rib is formed with a width smaller than the width of the lead storage groove, the solder will not be obstructed from wrapping around the lead end. Note that the part other than the solder pool is connected to the lead end. Since there is no extra gap between them, there will be no looseness between the capacitor body and the pedestal.

In this case, each lead storage groove 13.13 has the same shape, so to explain one of them, this lead storage groove 13 has a solder pool 13a whose groove width is increased at a position on the lead through hole 12 side. As shown in FIG. 3, the other portions, that is, the groove portions 13b on the side sides of the pedestal 10, have a width that does not create an unnecessary gap between them and the end portions 2a of the leads. . According to this embodiment, the solder pool 13a is formed in an arc shape around the lead through hole 12. Further, the ends 2a, 2a of the lead, in which the partition wall 14 is formed between the respective lead storage grooves 13, 13, are connected to the lead through holes 12.1.

FIG. 6 shows another configuration example of the present invention. According to this, the lead through hole 12.12 is similar to the above embodiment.
A rib 15.15 of a predetermined height is formed on the lead bending side of the lead to serve as a fulcrum during bending. When mounted, as illustrated in FIG. 7, the opposing side edges 10b, 10b are used as legs for the printed circuit board 9, and the central portion where the lead storage thin film 13 is formed is lifted from the printed circuit board 9. The taper 10a, 1 is supported as shown in FIG.

10b becomes a leg part. As shown in FIG. 8, the side edges 10b, 10b are formed with steeply rising tapers 10a, 10a, and the space between them is made flat to form a gap between the bottom surface of the pedestal 10 and the printed circuit board 9. A predetermined gap may be provided between the two.

According to this other configuration, by bending the end portion 2a of the lead at a larger angle using the rib 15 as a fulcrum in anticipation of its springback, the end portion 2a can be properly stored in the lead storage groove 13. In addition, a leg portion for the printed circuit board 9 is formed at a location distant from the end portion 2a of the lead, and the leg portion is connected to the printed circuit board 9.
Since it is a line contact, the stability during mounting is better than the conventional surface contact. Furthermore, since a gap is secured between the bottom surface of the pedestal 0 and the printed circuit board 9, the solder wrap-around property is improved. In this sense, in this case, there is no need to form a solder pool 13a in the lead storage groove 13 as in the above embodiment.

As explained above, according to the present invention, by forming a rib of a predetermined height on the lead bending side of the lead through hole to act as a fulcrum during bending, the bent end of the lead can be moved into the lead storage groove. In addition, in the first invention, by forming a solder pool in a predetermined part of the lead storage groove on the lead through-hole side, the groove width of which is larger than that of other parts, the solder can be stored properly. The embedding performance is greatly improved, and defects in soldering during surface mounting of chip-type electronic components are eliminated.
