欠点があった。(Prior art) Precious metals such as Au and Ag have excellent chemical and physical properties and are widely used in various electronic and electrical parts, but they are very expensive, so it is important to make the plating layer as thin as possible. is desired. On the other hand, true metal plating materials used as electronic and electrical components may be exposed to heat of several hundred degrees, and solderability may deteriorate due to oxidation of the underlying metal or diffusion of the underlying metal into the precious metal surface layer in such high-temperature environments. However, there were disadvantages in that the bonding properties and the like were significantly deteriorated and the color changed.

Even with these base platings, if kept in the atmosphere at 450°C for 3 minutes, the noble metal plating layer will change to, for example, Au0.
.. A material that exhibits sufficient solderability and bonding properties cannot be obtained with a plating thickness as thin as 1μ or A g 0.5μ, and in order to satisfy the above characteristics, the precious metal plating layer must be plated as thick as several μ. The disadvantage was that it had to be done. As described above, conventional underplating products consume large amounts of precious metals, resulting in significant economic losses.

ある前記電子・電気機器用部品に関するものである。(Structure) The present invention was achieved as a result of intensive research in view of the current situation, and the precious metal plating layer was kept in the atmosphere at 450°C for 3 minutes at a thin plating thickness of about 001 μm of Au or 0.5 μm of Ag. The object of the present invention is to provide a precious metal plating material that exhibits sufficient solderability and bonding properties even after soldering. That is, the present invention provides a gold or silver base plating layer on a metal plate, and a silver or silver alloy plating on the base plating layer when the base plating layer is gold plating, and gold or gold when the base plating layer is silver plating. The present invention relates to parts for electronic and electrical equipment having an alloy plating layer, and parts for electronic and electrical equipment in which the base plating layer is a gold or silver strike plating layer.

If the thickness is 0.01 μm or more, the effect of improving so-called heat resistance, which maintains good solderability and bonding properties even after heating, is sufficient. Therefore, 0.01 like this
In order to apply a thin plating layer of about .mu. to 0.1 .mu.m, it is preferable to use a strike plating bath because a dense and uniform film can be obtained. The main silver strike plating solution can be used for copper, copper alloys, iron alloys, etc., and strike plating is usually performed using a particularly low concentration silver plating solution. This is because silver cementation occurs instantaneously when immersed in a highly concentrated silver plating bath, and even if gold plating is applied on top of that, a film with good adhesion cannot be obtained. Further, the underlying gold strike liquid can be similarly used for copper, copper alloys, iron alloys, etc. Strike plating is then typically performed using a gold plating solution with a low concentration. By using the strike plating solution as described above, a highly uniform, dense, and highly adhesive film is formed, and then a predetermined upper layer plating is performed. Equipment parts can be obtained.
このような金あるいは銀めっき材の高温環境下において

ボンディング性を悪化させる原因となる。Although the mechanism by which such gold or silver plated materials deteriorate in high-temperature environments has not necessarily been theoretically elucidated, it is generally thought to be as follows. In other words, in the case of gold-plated materials, Cu, Fe,
Ni, Co, etc. diffuse onto the gold-plated surface and come into contact with the atmosphere, forming oxides and causing deterioration of solderability or bonding properties. In addition, in the case of silver-plated materials, oxygen easily permeates under high-temperature environments, so oxygen combines with the base metal or the conventional base plating, which similarly leads to the formation of an oxide film and reduces solderability. Alternatively, it may cause deterioration of bonding properties.

ある。Therefore, in the present invention, by applying silver plating, which is a dissimilar metal, as the base plating for gold or gold alloy plating material, the formation of the above-mentioned oxides in front of the gold plating is prevented,
Furthermore, gold plating is applied as a base plating for silver or silver alloy plated materials to prevent oxidation of the base.

Wedge bonding was performed, and the bonding properties were evaluated based on the tensile strength.
以下余白 第1表 半田付性及びボンディング性 ×半田付性 T2: −全く濡れを示さない。Margin below Table 1 Solderability and bonding properties x Solderability T2: - No wetting at all.
外観状況二 096%以上の襦れを示した。Appearance condition: 2096% or more of curvature.
X 40%未満の濡れを示した。X: Showed less than 40% wetting.
※ボンディング性 二 −ボンディングできない。*Bonding property 2 - Bonding is not possible.
第1表に示すように本発明例では比較例に比べ450℃
、3分間の加熱処理後の半田付は性及びボンディング性
に優れていることが分かる。As shown in Table 1, the inventive example had a temperature of 450°C compared to the comparative example.
It can be seen that soldering after 3 minutes of heat treatment has excellent soldering properties and bonding properties.
