Contactor for electronic components and test method using the same

1. A contactor configured to be electrically connected to terminals of an electronic component, comprising:

a plurality of contact electrodes configured to contact the terminals of the electronic component; and

a plurality of elastic electrodes each composed of an electrically conductive elastic body, the elastic electrodes being configured to generate a pressing force for pressing the contact electrodes against the terminals of the electronic component,

wherein the contact electrodes are separable from the elastic electrodes;

a single contact electrode holding part configured to hold the contact electrodes; and

an elastic electrode holding part configured to hold the elastic electrodes,

wherein the contact electrode holding part is a component separate and separable from the elastic electrode holding part; and

wherein the contact electrodes are in contact with the elastic electrodes in a non-fixed manner.

2. The contactor as claimed in claim 1 , wherein:

the contact electrode holding part is a plate-like member; and

the contact electrodes are supported movably in openings provided through the plate-like member.

3. The contactor as claimed in claim 2 , wherein the contact electrode holding part includes a positioning mechanism that positions the electronic component.

4. The contactor as claimed in claim 3 , wherein the positioning mechanism is configured to guide the electronic component to a predetermined position based on a shape of the electronic component.

5. The contactor as claimed in claim 2 , wherein an axial direction of each opening of the contact electrode holding part is different from a direction of the pressing force generated by the elastic electrodes.

6. The contactor as claimed in claim 2 , wherein a direction in which each contact electrode moves in a corresponding one of the openings of the contact electrode holding part is inclinable with respect to a direction of the pressing force generated by the elastic electrodes.

7. The contactor as claimed in claim 2 , wherein:

the contact electrode holding part includes opposite first and second faces, the first face opposing the electronic component; and

the openings are spaced on the first face with a pitch different from a pitch with which the openings are spaced on the second face.

8. The contactor as claimed in claim 2 , wherein each contact electrode is bent in a corresponding one of the openings and is elastically deformable by the pressing force from the elastic electrodes.

9. The contactor as claimed in claim 1 , wherein the contact electrode holding part is integrated with the contact electrodes as a single unit.

10. The contactor as claimed in claim 1 , wherein each of the contact electrodes has opposite first and second ends that are shaped differently, the first end being shaped in accordance with a shape of a corresponding one of the terminals of the electronic component, the second end being shaped suitably for a flat electrode.

11. A contactor configured to electrically connect a circuit board to a terminal of an electronic component, comprising:

a first contact electrode configured to contact the terminal of the electronic component;

a second contact electrode configured to contact a terminal of the circuit board; and

an elastic electrode formed of an electrically conductive elastic body, the elastic electrode being provided between the first and second contact electrodes,

wherein at least one of the first and second contact electrodes is separable from the elastic electrode;

a first contact electrode holding part holding the first contact electrode;

a second contact electrode holding part holding the second contact electrode; and

an elastic electrode holding part holding the elastic electrode, wherein at least one of the first contact electrode holding part and the second contact electrode holding part is a component separate and separable from the elastic electrode holding part; and

wherein the first contact electrode is in contact with the elastic electrode in a non-fixed manner, and the second contact electrode is in contact with the elastic electrode in a non-fixed manner.

12. The contactor as claimed in claim 11 , wherein at least one of the first and second contact electrodes is inclinable with respect to a direction of a pressing force generated by the elastic electrode.

13. The contactor as claimed in claim 11 , wherein at least one of the first and second contact electrodes is elastically deformable by a pressing force from the elastic electrode.
