Detection system and method based on relative quality index early warning

Abstract

The invention discloses a detection system and method based on relative quality index early warning. The detection system comprises a detection module, a data acquisition module, a quality analysis module, a judgment module and an early warning module; the detection module detects actual parameters of the product; the data acquisition module sends the actual parameters to the quality analysis module; the quality analysis module calculates the relative quality index of the product according to the actual parameters of the product; an early warning quality index is preset in the judgment moduleand used for comparing the relative quality index with the early warning quality index; and the early warning module gives an alarm when the relative quality index is lower than the early warning quality index. The system is built in a modular mode, the quality of a product can be detected, the relative quality index mathematical model is built, the relative quality index curve is drawn, an alarmis given out in real time for the product batch lower than the early warning quality index line, and therefore adjustment of front-end production process parameters is guided in time. The system has the advantages of quality evaluation, real-time early warning, improvement of the yield, reduction of the production cost and the like.

Description

technical field [0001] The invention relates to the technical field of product detection, in particular to a detection system and method based on relative quality index early warning. Background technique [0002] With the advent of the Industry 4.0 era, industrial manufacturing informatization is an inevitable requirement, and all production links will form a closed-loop networking link through big data. Product testing is the guarantee of product quality and an important part of the production process. Currently, inspection systems on the market only sort qualified or unqualified products, and are optimized in terms of inspection efficiency and manufacturing costs, such as Chinese patent applications 201610722201.1 and 201811227797.3. With the rapid development of integrated circuits, the improvement of detection efficiency has been very limited. And the manufacturing cost of the product is only realized by reducing the manufacturing cost of the detection system, which c...
