した。(Problems to be Solved by the Invention) By the way, all of the composite materials with solder made by the above-described method for manufacturing the composite material with solder are thin solder, so that the solder volume is reduced and the solder is often insufficient. It was Therefore, although the solder was replenished by the auxiliary soldering work, the solder thickness was uneven, and when the composite material was soldered, the bonding strength was weak and the dispersion was large and unstable. In addition, the replenishment of the solder attached the solder to an unnecessary portion, and the composite material was contaminated.
そこで本発明は、半田付けに十分なボリュームの半田

ある。Thus, the present invention seeks to provide a method of making a composite material with a sufficient volume of solder for soldering.

It is characterized in that a groove is provided in the longitudinal direction on the other side of the similar strip-shaped metal material, and molten solder is poured into the groove by a nozzle.

Composite materials with different volumes of solder are obtained. Further, since the band-shaped metal material having the solder thickened has already undergone the intermediate heat treatment and the heat treatment straightening step, it is not necessary and the solder is not melted.

Molten solder (Pb40% -Sn60%) 6 was poured into the groove 3 with a nozzle 5 equipped with a heater 4 on the outer periphery, and 20 to 22 μm of solder 6 was thickened as shown in FIG. A composite material 7 was obtained with a sufficient volume of solder 6.

足なので補助半田作業により半田を補充した。On the other hand, as a conventional example, one side of the same strip metal material as in the above-mentioned embodiment has a width of 3 mm in one longitudinal direction and a thickness of 0.01 mm of Ag-Pd 50%.
After stack-bonding the strip-shaped metal sheets, the other side end longitudinal direction of the strip-shaped metal material was immersed in a molten solder bath to obtain a composite material having a solder having a thickness of 2 to 3 μm. Since this composite material lacks solder, supplementary solder was used to supplement the solder.

の表に示すような結果を得た。The composite material with solder of the example and the conventional example manufactured in this way is punched and processed such as cutting to make a contact for a connector, which is made into a base material made of copper with a thickness of 1 mm, a width of 10 mm, and a length of 50 mm. After soldering and measuring the bonding strength, the results shown in the following table were obtained.

く安定していることが判る。 As is clear from the above table, the soldering joint strength of the connector contactor made of the soldered composite material of the embodiment is the same as that of the connector contactor made of the conventional soldered composite material. It can be seen that the bond strength is higher than the bonding strength and the dispersion is small and stable.

う効果を奏する。(Effect of the invention) As can be seen from the above description, in the method for manufacturing a composite material with solder of the present invention, the molten solder is poured into the groove provided in the strip-shaped metal material having a thickness close to the final finish, so that the solder can be thickened. As a result, a composite material having a sufficient volume of solder for soldering can be obtained. Then, the electric contact made of the composite material including the solder has an effect that it has a high bonding strength by soldering with the base material and has little variation and becomes stable.
