  • Electrical testing device and electrical testing method with control of probe contact pressure
    Patent number: 8183878
    Abstract: An electrical testing device has a first probe that electrically contacts with an inspection device, a second probe that is electrically connected to the first probe and electrically contacts with an external terminal of a test object, a cylinder that houses the first probe and second probe, and into which and out of which a fluid flows between the first probe and second probe, and a fluid pressure regulator that controls the fluid pressure in the cylinder. The fluid pressure in the cylinder controls the contact force between the first probe and the inspection device and the contact force between the second probe and the external terminal.
