On the other hand, 17 is a solder jet nozzle, and jet solder wave 19 by this is jetted to a height over the solder liquid surface 18 and hitting the soldering surface 16. Further, 20 and 20 are lifter claws of an object to be soldered provided facing the flow solder bath,
Can be supported at the above height and guided to the position of the nozzle 17.

The lifter claws 20, 20 are located inside the bottom surface of the housing 15 and support the printed circuit board 14 and the housing 15 via a holding plate 21. The holding plate 21 is a frame body formed to be slightly smaller than the housing 15 and fitted inside. Reference numeral 22 is a punching hole for forming a stopper (not shown) of the printed board 14, and 23 is a partition plate formed integrally with the housing 15.

In the printed circuit device 11 shown in FIG. 5, since the partition plate 23 is integrated with the housing 15, a means for holding the printed board 14 cannot be formed, so that the printing inside the housing 15 is performed on the soldering surface side of the printed board 14. The lower board positioning plate 21 is held by the lifter claws 20 and soldered.

By the way, in this type of soldering method, a normal jet solder wave is used.
It is said that as the height of 19 is increased, the jet state becomes more unstable and the quality of soldering deteriorates. In particular, when there is a leadless component such as the chip component 13, the height of the soldering surface becomes uneven, and if the jet solder wave 19 is higher than a predetermined value, the flux gas generated from the molten solder can move stably. Instead, it causes soldering failure.

Considering such conditions of the jet solder crest value, in the case of FIG. 5, since the lifter claw 20 is supporting the device 11 from the bottom surface, the soldering surface 16 is 20 minutes away from the solder liquid surface 18. However, it was pointed out that the problem was that the soldering cost became too high and good soldering could not be performed.

That is, in the case of the flow soldering method as shown in FIG. 5, the soldering surface
The height H of 16 is a distance h from the bottom surface of the housing 15 to the printed board 14 and a distance g from the solder liquid surface 18 to the lifter claw 20 (a distance for preventing the nozzle 17 and the lifter claw 20 from hitting each other). )
In addition, the thickness t of the lifter claw 20 is added (however, the gap x between the bottom surface of the housing and the lifter claw 20 is ignored). Therefore, H is required as the height of the jet solder wave 19. However, the height of the jet solder wave 19 is optimally about 8 [mm], and when g is constant, g + h is 8 [mm].
If it exceeds, the optimum value will be exceeded,
Soldering performance deteriorates.

(Problems to be Solved by the Invention) Conventionally, a printed circuit device that is soldered by using an injection nozzle does not have a holding means for a printed circuit board housed in a housing. Therefore, when soldering, a lifter claw is used. The printed board is held by inserting the inside of the housing from the bottom side. Therefore, the height H of the printed circuit device from the liquid surface of the solder is required to be extra by the thickness t of the lifter claw, in addition to the distance g at which the bottom of the housing and the nozzle do not normally hit. For this reason, the position of the printed circuit board with respect to the solder liquid level becomes high, and the wave height of the jet solder wave must be increased, and there is a problem that the reliability of soldering decreases.
