Abstract

A probe card management system includes inspection apparatuses that inspect an inspection object and a management apparatus that manages a state of a probe card. Each inspection apparatus includes a camera that captures an image of a tip of each needle provided on the probe card, an inspection part that measures a state of the tip from the image, and inspects the inspection object by bringing the tip into contact with each test pad based on the measurement result, and supplying an electrical signal to the inspection object through the tip; and a transmission part that transmits the measurement result and a number of executions of the inspection to the management apparatus. The management apparatus includes a threshold specification part that specifies a first threshold value, and a notification part that notifies an outside of the number of executions and the first threshold value.
