Abstract
An apparatus and method for inspecting a circuit board is described which can well absorb a variation in a height of an electrode to be inspected and can maintain an insulating property between adjacent inspection electrodes even if the electrode to be inspected is arranged at a fine pitch.
Claims4
A relay board that includes a board through which a plurality of rigid conductor electrodes penetrate, wherein the plurality of rigid conductor electrodes is held to be movable in a direction of a thickness of the board,
- the board has an insulating property and a plurality of through holes is formed on the board,
- the rigid conductor electrode includes a drum portion inserted in the through holes and a terminal portion formed on each end of the drum portion, each having a larger diameter than a diameter of the through hole, and
- the rigid conductor electrode is held in the through hole of the board so as to be movable in the direction of the thickness of the board such that the distance between the terminal portion and an opening of the through hole changes.
