Abstract
One aspect of the present disclosure relates to a method of setting up a test apparatus that is a method of setting up the test apparatus to test a substrate by bringing a probe into contact with an electrode pad formed on a chip on the substrate that is mounted on a stage. The method includes acquiring a first image including the probe in a probe card that is attached to the test apparatus. The method includes calculating first information including a center of gravity, and an angle, for the probe card, based on probe information including a position of the probe that is calculated based on the first image; and probe information or pad information that is pre-provisioned and corresponds to the probe card. The method includes acquiring a second image including the electrode pad on the substrate mounted on the stage. The method includes calculating second information including a center of gravity of the chip and an angle for the substrate, based on pad information that includes a position of the electrode pad and is calculated based on the second image; and pad information that is pre-provisioned and corresponds to the substrate. The method includes outputting the first information and the second information.
