The invention discloses an integrated circuit testing device, which belongs to the technical field of integrated circuit testing. An integrated circuit testing device includes a testing host, which is connected to a computer through a PCI bus, connected to an integrated circuit through a relay matrix, and the testing host There are multiple test extensions on the machine. The present invention provides a high-precision integrated circuit test equipment that integrates portable testing and desktop testing technologies. The present invention uses test extensions as the main test equipment, and can carry out portable testing at any time. , the test host is used as a connection auxiliary carrier for multiple test extensions, which enables multiple test extensions to simultaneously test the same integrated circuit, and concentrates on analyzing multiple test results to reduce test errors. Collect and calibrate the signal data, analyze the test performance of the test extension, detect and improve the test accuracy of the test extension.
Description
technical field [0001] The present invention relates to the technical field of integrated circuit testing, and more particularly, to an integrated circuit testing device. Background technique [0002] An integrated circuit is a miniature electronic device or component. Using a certain process, components and wirings such as transistors, resistors, capacitors and inductors required in a circuit are interconnected, fabricated on a small or several small semiconductor wafers or dielectric substrates, and then packaged in a package. , become a miniature structure with the required circuit functions; in which all components have been formed into a whole in structure, making electronic components a big step towards miniaturization, low power consumption, intelligence and high reliability. It is represented by the letters "IC" in the circuit. [0003] Integrated circuit testing is the process of testing integrated circuits or modules to determine or evaluate the function and perf...
