Problems solved by technology

Therefore, once the calibration interface board design is fixed, it cannot be changed with different resource boards configured by ATE
As a result, ATE machines with different configurations require different calibration interface boards. As the number of calibration board interface boards increases, manufacturing costs and management costs will increase.

Abstract

The invention discloses a calibration interface board and system for a universal card slot of integrated circuit automatic test equipment, and belongs to the technical field of integrated circuit automatic test, the calibration interface board comprises a basic connection board, the basic connection board is provided with a plurality of standard interfaces with first signal ports and second signal ports side by side at intervals, the first signal port of each standard interface is externally and electrically connected with a calibration source and a measuring instrument through a circuit bus and is also used for being electrically connected with an ATE resource board card located in a universal card slot of an ATE machine, and the second signal port of each standard interface is electrically connected with a board card calibration card corresponding to the calibration requirement of the ATE resource board card. According to the calibration interface board and system for the universal card slot of the integrated circuit automatic test equipment, the functions are integrally designed, the operation is flexible, and the applicability is high.

Description

technical field [0001] The invention belongs to the technical field of automatic testing of integrated circuits, and in particular relates to a calibration interface board and a system for a universal card slot of automatic testing equipment of integrated circuits. Background technique [0002] ATE (Automatic Testing Equipment) used in large-scale automated testing of integrated circuits has the characteristics of high integration, high precision, and high stability. High integration not only means that a single ATE device generally has hundreds of thousands or even tens of thousands of input and output (I / O) channels to meet the needs of parallel testing of as many large-scale integrated circuits as possible; it also means that a single ATE device generally has different test resources. , presented in various types of resource boards; to meet the test requirements of different types of integrated circuits or system-on-chip (SoC) chips for different modules. High precision ...
