Definitions
- the present invention relates to an Ag—Pd—Cu alloy for electrical and electronic equipment.
- shapes such as cantilevers, cobras, and springs are used for the probe pins for inspection depending on the object to be inspected, and the required characteristics are different. If the emphasis is on hardness, Pt alloy, Ir alloy, etc. that show high hardness in the state of plastic working, or Au alloy, Pd alloy, etc. that show high hardness in the state of precipitation hardening are recommended.
- the present invention improves the mechanical properties as an alloy by adding a specific element of Pt 1.0 to 20% by mass to Ag 20 to 40% by mass, Pd 20 to 40% by mass and Cu 10 to 30% by mass. That is, a material for electrical and electronic use having a hardness at the time of precipitation hardening after plastic deformation of 340 to 420 HV, improved bending strength, and improved corrosion resistance.
- the reason why the addition amount of Pt is set to 1.0 to 20% by mass is to improve the bending strength, and if it is less than 1.0% by mass, the effect of improving the bending strength cannot be obtained. This is because if it exceeds mass%, a predetermined hardness cannot be obtained.
- an alloy containing 0.1 to 10% by weight of Au, Re, Rh, Co, Ni, Si, Sn, Zn, B, In At least one of them is added in an amount of 0.1 to 3.0% by mass.
- the reason for adding 0.1 to 10% by mass of Au is to improve the hardness and to obtain oxidation resistance. When the content is less than 0.1% by mass, there is no effect. This is because processability is deteriorated.
- the reason for adding 0.1 to 3.0% by mass of at least one of Re, Rh, Co, Ni, Si, Sn, Zn, B, and In is to improve hardness. If the amount is less than 0.1% by mass, the effect is not obtained. If the amount exceeds 3.0% by mass, the workability deteriorates. Re, Rh and Ni also act as an effect material for refining crystal grains.
- the material has excellent corrosion resistance with low contact resistance, hard hardness, strong bending strength, and excellent workability.
- test piece ( ⁇ 1.0 mm ⁇ L200 mm) was drawn as described above, and the conditions for precipitation hardening were 300 to 500 ° C. ⁇ 1 hr in a mixed atmosphere of H 2 and N 2 . Moreover, the hardness of the test piece was measured by HV0.2 using a Vickers hardness tester for the surface hardness.
- the bending strength was examined by fixing the test piece with an R0.5 jig, repeatedly bending the test piece until it broke, and investigating the number of bendings that led to the breakage. In addition, it counts once when turning 90 degrees, and 0 times means what did not bend to 90 degrees.
- Table 1 shows the composition of each example, and shows the hardness after the number of bending processes leading to breakage and after precipitation hardening.
- the precipitation hardening material of the comparative example in which Pt was not added to Ag—Pd—Cu was weak in bending strength and could not be folded twice or more, but it was broken, but Pt was added. Can be bent twice or more, and it was confirmed that the bending strength was improved.
- precipitation hardening materials of alloys obtained by adding at least one of Pt, Au, Re, Rh, Co, Ni, Si, Sn, Zn, B, and In to Ag—Pd—Cu of Examples 2 to 6 are also included. Two or more folds were possible.

Abstract
Description
しかし、半導体集積回路の検査用プローブピン等のように、使用用途によっては、低い接触抵抗や耐食性の他に、硬さ、耐摩耗性なども要求される。
そのような場合、塑性加工を施した状態で高い硬さを示すPt合金、Ir合金等や析出硬化するAu合金、Pd合金等が好んで使用されている(例えば、特許文献1参照)。
硬さを重視した場合には、塑性加工を施した状態で高い硬さを示すPt合金、Ir合金等もしくは、析出硬化を施した状態で高い硬さを示すAu合金およびPd合金等が推奨される。
そのため、先端に曲げ加工を施すタイプのプローブピンの場合、折り曲げ加工時もしくはプローブピンとして使用したときに発生する折り曲げ個所への疲労が原因で、プローブピンの曲げ個所が折損してしまう場合がある。
そこで、先端に曲げ加工を施すタイプのプローブピンの場合は、低い接触抵抗、耐食性、硬さに加えて折り曲げ強さを有する材料が求められている。
ここで、Ptの添加量を1.0~20質量%とした理由は、折り曲げ強さを向上させるためであり、1.0質量%未満では折り曲げ強さの向上の効果が得られず、20質量%を超えると所定の硬さが得られないためである。
なお、Auを0.1~10質量%添加する理由は、硬さを向上させるためおよび耐酸化性を得るためであり、0.1質量%未満ではその効果がなく、10質量%を超えると加工性が悪くなるためである。
なお、本実施例では、真空溶解にてAg-Pd-Cu合金にPtを添加した合金インゴット(φ10mm×L100mm)を作製した。
表1に各実施例の組成を示し、折損に至る折り曲げ回数加工後および析出硬化後の硬さを示す。
同様に、実施例2~6のAg-Pd-CuにPtおよびAu、Re、Rh、Co、Ni、Si、Sn、Zn、B、Inのうち少なくとも1種を添加した合金の析出硬化材も2回以上の折り曲げが可能であった。
Claims (2)
- Ag20~40質量%、Pd20~40質量%、Cu10~30質量%およびPt1.0~20質量%よりなり、塑性加工後の析出硬化時の硬さを340~420HVとし、かつ折り曲げ強さを有していることを特徴とする電気・電子用材。
- 請求項1の合金に、用途により特性を改善する添加元素として、Au0.1~10質量%、Re、Rh、Co、Ni、Si、Sn、Zn、B、Inのうち少なくとも1種を、0.1~3.0質量%添加したことを特徴とする電気・電子用材。
