Claims

[Scope of utility model registration request]

an automatic feeding device that automatically sequentially feeds a large number of integrated circuits to be measured stored in a storage case one by one and attaches them to a test head; and a signal is applied to an input terminal of the integrated circuit;
Furthermore, a test head for connecting the signal from the output terminal to a measuring instrument, a storage device for storing programs and measurement results necessary for measuring the characteristic values of the integrated circuit, and the storage device; In automatic integrated circuit testing equipment, which consists of a central processing unit that receives data and provides control signals to signal sources and measuring instruments, and a printer that prints measurement results, etc., the integrated circuit under test is sent out from the storage case. An identification number printing device that prints an identification number in the form of a code, number, symbol, or a combination thereof to identify a large number of integrated circuits under test on the body or terminals of the integrated circuits before they are mounted on a test head. a counter for instructing the identification number printing device to print an identification number by sequentially incrementing or decrementing the identification number so that the identification number printed by the printing device does not overlap with a large number of integrated circuits under test; and the printing device 1. An automatic integrated circuit testing device comprising: an identification number reading device for reading an identification number printed by an integrated circuit.
