Abstract
Official abstract text for this publication.
Provided is an electrical contact member which is capable of maintaining stable conductivity over a long period of time, while achieving low adhesion to a test subject, in particular, an electrical contact member which is capable of maintaining stable electrical contact over a long period of time by suppressing increase in the contact resistance, while achieving low adhesion to a test subject even after repeated contact at high temperatures around 85° C. or after being left in the atmosphere for a long period of time. The present invention relates to an electrical contact member, which repeatedly comes into contact with a test subject, and wherein the surface of the electrical contact member, said surface coming into contact with the test subject, is configured of a carbon coating film that contains Pd.
First claim
Opening claim text (preview).
The invention claimed is: 1. An electrical contact member configured to contact a test subject repeatedly, wherein a surface of the electrical contact member configured to come into contact with the test subject is a carbon coating film that comprises Pd, and wherein the electrical contact member has a topmost surface comprised of a Be—Cu alloy, a layer of an Au—Co alloy present on the topmost surface, a Layer of Ni on said layer of an Au—Co alloy, a layer of Cr on said layer of Ni, and said carbon coating film that comprises Pd present on said layer of Ni. 2. The electrical contact member according to claim 1 , wherein the content by percentage of Pd present in the carbon coating film is from 10 to 50% by atom. 3. The electrical contact member according to claim 2 , wherein the content by percentage of Pd present in the carbon coating film is from 10 to 23% by atom. 4. The electrical contact member according to claim 1 , wherein the carbon coating film has a thickness of 5 nm to 10 μm. 5. The electrical contact member according to claim 2 , wherein the carbon coating film has a thickness of 5 nm to 10 μm. 6. The electrical contact member according to claim 3 , wherein the carbon coating film has a thickness of 5 nm to 10 μm. 7. The electrical contact member according to claim 1 , wherein the carbon coating film has a thickness of 5 nm to 200 nm, and the content by percentage of Pd present in the carbon coating film is from 10 to 23% by atom. 8. The electrical contact member according to claim 1 , wherein the test subject to be examined comprises Sn. 9. A connecting device for examination, comprising the electrical contact members as recited in claim 1 . 10. A connecting device for examination, comprising the electrical contact members as recited in claim 8 . 11. The electrical contact member according to claim 1 , wherein the carbon coating film has a thickness of 5 to 200 nm, and the content by percentage of Pd present in the carbon coating film is from 10 to 50% by atom. 12. The electrical contact member according to claim 1 , wherein the carbon coating film has a thickness of 5 to 200 nm, and the content by percentage of Pd present in the carbon coating film is from 15 to 40% by atom. 13. The electrical contact member according to claim 1 , wherein the carbon coating film has a thickness of 5 to 200 nm, and the content by percentage of Pd present in the carbon coating film is from 20 to 35% by atom. 14. The electrical contact member according to claim 1 , wherein the carbon coating film has a thickness of 5 nm to 600 nm, and the content by percentage of Pd present in the carbon coating film is from 10 to 23% by atom. 15. The electrical contact member according to claim 1 , wherein the carbon coating film has a thickness of 5 nm to 400 nm, and the content by percentage of Pd present in the carbon coating film is from 10 to 23% by atom.
