本発明は、セラミックス基板等への接合の為にその端面
にろう材を有する集積回路装置用リードビンの製造方法
に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a lead bin for an integrated circuit device, which has a brazing material on its end face for bonding to a ceramic substrate or the like.

セットしてろう付が行なわれていた。Generally, when brazing a lead bottle to a metallized ceramic substrate, etc., copper or F as shown in Figure 1 is used.
Lead bin made of e-N1 alloy! Brazing was performed by setting the soldering material 2 and the brazing filler metal 2 on the ceramic substrate 3 using a jig 4 as shown in FIG.
(1)

なわれていた。(1) When the lead bottle 1 is soldered to the ceramic base 11i3 through the brazing material 2 as shown in FIG. 2, insertion of the brazing material is often forgotten. To prevent this, as shown in Figure 3, the brazing filler metal 2 is placed in the lead bin 1
A lead bin 11 is used, which is attached to the lead bin 1. To attach the brazing filler metal 2 to the lead bin 1, heat the lead bin 1 and the brazing filler metal 2 in a stacked state, melting the brazing filler metal 2, and attaching the brazing filler metal 2 to the lead bin L. Crafting was done using fused cladding.

うと共にその後の表面処理工程で事故を誘(2)
発する場合があった。However, in this method, as shown in FIG. 4, the brazing filler metal 2 sometimes wraps around to a portion of the lead bin l other than the bonding surface 1a with the ceramic substrate or the like, that is, to the side surface 1b thereof. In this way, the brazing filler metal 2 is placed on the side 1 of the lead bin l.
When the brazing filler metal 2 is melted and clad in a state where it has spread to the ceramic substrate 3, the amount of brazing filler metal 2 used is only the amount necessary for brazing with the ceramic substrate 3, and it spreads to unnecessary parts other than the joint surface 1a. There were cases where the wax flowed, reducing the brazing strength and causing accidents during the subsequent surface treatment process (2).
本発明は、上述した諸事情に鑑みて成されたものであり

のである。The present invention has been made in view of the above-mentioned circumstances, and provides a method for manufacturing a brazed lead bin in which the brazing material does not go around to parts other than the bonding surface of the lead bin with a ceramic substrate, etc., that is, to the side surface of the lead bin. This is what we intend to provide.

。The present invention involves the steps of heating a long wire made of Kovar or Fe-Ni alloy in an oxidizing atmosphere, cutting the wire into a predetermined length, and cutting the cut surface of the cut wire into a predetermined length. This method is characterized by the step of melting and cladding the brazing filler metal in a vacuum or an inert atmosphere.

かつ側面の酸化物を還元させない為である。However, as shown in FIG. 5a, when a long wire 5 made of Kovar or Fe-N1 alloy is heated in an oxidizing atmosphere, an oxide film 6 is formed on the surface of the wire 5. 6. Next, this wire 5 is cut into a predetermined length as shown in FIG. 5 to form a lead bin 51. Its cut surface 5
a is not oxidized, and when the cut surface 5a is then melted and clad with the brazing material 2, the cut surface 5a can be easily melted and clad with the solder material 2 (3). Furthermore, at this time, since the oxide skin 116 is formed on the side surface of the lead bin 51, the brazing material 2 does not flow to the side surface.
It is possible to clad only the cut surface 5a of the beam dobbin 5'. The reason why the melt cladding of the brazing material 2 onto the lead bin 51 is carried out in a vacuum or in an inert atmosphere is to prevent the cut surface 5a of the lead bin 5' from being oxidized and the oxide on the side surface from being reduced.

When we investigated the cladding state of the brazing filler metal in each piece, we found that none of the dobbins obtained using the manufacturing method of the present invention had the brazing filler metal wrapping around the sides. In all solder dobbins obtained by conventional methods, the filler metal was wrapped around the sides.

In addition, the brazing material is cradled only on the joint surface with the ceramic substrate, without going around the side of the lead bottle where an oxide film is formed, which is sufficient for brazing the ceramic substrate, etc. and the lead bottle. A brazed pin with brazing strength can be easily obtained.
