Abstract
An electrical connection device includes: a wiring board in which lands are arranged on a main surface; and probes. Each of the probes has a distal end portion that contacts an object to be measured and a proximal end portion that contacts the land. A material of a surface film of the proximal end portion, which contacts the land, is a metal material different in composition from a material of the land that contacts the surface film.
Claims8
An electrical connection device for use in measuring electrical characteristics of an object to be measured, comprising:
- a wiring board in which lands made of a conductive material are arranged on a main surface;
- and
- a probes, each of which has a distal end portion that contacts the object to be measured during measurement and a proximal end portion that contacts the land during the measurement, and in each of which a material of a surface film of the proximal end portion, the surface film contacting the land, is a metal material different in composition from a material of the land that contacts the surface film.
The electrical connection device according to 1, wherein the proximal end portion of each if the probes has a structure of including a base film that covers a core material and the surface film that covers the base film.
