Definitions
- the present invention relates to a Pd alloy that can be used as a material for electrical and electronic equipment.
- the materials used for electrical and electronic equipment are required to have various characteristics such as low contact resistance and excellent corrosion resistance. Therefore, expensive noble metal alloys such as Pt alloy, Au alloy, Pd alloy, and Ag alloy are widely used.
- Patent Document 1 In addition to low contact resistance and corrosion resistance, hardness (abrasion resistance) and the like are required depending on the purpose of use (such as an inspection probe for a semiconductor integrated circuit). Therefore, Pt alloy, Ir alloy, etc., Au alloy, Pd alloy, etc. that are hardened by precipitation are preferably used (for example, Patent Document 1 and Patent Document 2).
- probes various types (shapes) of cantilevers, cobras, springs, etc. are used for inspection probes (hereinafter referred to as probes) for semiconductor integrated circuits, etc., depending on the inspection object, and the required characteristics also depend on the probe type. Each is different.
- a material having a high hardness by precipitation hardening treatment often has a high hardness and, at the same time, a difficulty in drawing and a weakness (brittleness) against bending. Therefore, in the case of a probe that bends at the tip, even if wire drawing is possible, it is performed after the probe pin is incorporated into the probe card at the time of bending the probe pin or at the time of characteristic inspection of a semiconductor integrated circuit, etc.
- the bending portion of the probe may be damaged due to fatigue at the bending portion that is subjected to repeated operation tests of tens of thousands of times.
- Patent Document 3 In response to such demands on mechanical properties, it has been proposed to improve the weakness (brittleness) against bending by adding Pt 1.0 to 20 mass% to the Pd alloy (for example, Patent Document 3).
- the present invention provides an Ag—Pd—Cu alloy composed of 20 to 50% by mass of Ag, 20 to 50% by mass of Pd, and 10 to 40% by mass of Cu, 0.1 to 5.0% by mass of Co and / or 0.1 to 5% of Ni. It comprised by adding 0 mass%.
- the reason why the added amount of Co is 0.1 to 5.0% by mass is to improve bending workability, and if it is less than 0.1% by mass, the effect of improving bending workability does not appear. It is because workability will fall when it exceeds 5 mass%.
- the reason why 0.1 to 10% by mass of Au is added is to improve the oxidation resistance and hardness. If the content is less than 0.1% by mass, the effect is not obtained. This is because it gets worse.
- the reason for adding at least one of Pt, Re, Rh, Ru, Si, Sn, Zn, B, In, Nb, and Ta by 0.1 to 3.0% by mass is to improve the hardness. It is. Re, Rh and Ru also act as elements having an effect of refining crystal grains.
- the mechanical properties of the alloy are improved, that is, the hardness during precipitation hardening after plastic working is 280 to 480 HV, and the corrosion resistance is low, the hardness is hard, and the bending workability is high.
- the material cost is reduced.
- An ingot ( ⁇ 10 ⁇ L100) was prepared by adding Co and / or Ni to an Ag—Pd—Cu alloy by vacuum melting and further adding an additive element that improves the characteristics depending on the application.
- test piece ( ⁇ 1.0 ⁇ L) was drawn so as to be, and the conditions for precipitation hardening were 300 to 500 ° C. ⁇ 1 hr in a mixed atmosphere of H 2 and N 2 .
- the hardness of the test piece was measured at HV0.2 with a surface hardness pickers hardness tester.
- test piece 1 was fixed with an R0.5 jig 2 and repeatedly bent until the test piece broke, and the number of bendings until the test piece was broken was investigated. In addition, it counted once when turning 90 degree
- Table 1 shows the composition list of the examples, the number of bendings until breakage, and the hardness after processing and precipitation hardening.
- the Ag—Pd—Cu alloy may be made of Co and / or Ni, and at least one of Au, Pt, Re, Rh, Ru, Si, Sn, Zn, B, In, Nb, and Ta. It was possible to confirm that the precipitation hardened material of the alloy added with bismud could be bent twice or more, and the bending workability was improved.
