A 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, comprising a detection module, a data acquisition module, a quality analysis module, a judgment module and an early warning module; the detection module detects the actual parameters of a product; For the quality analysis module; the quality analysis module calculates its relative quality index according to the actual parameters of the product; the judgment module presets the early warning quality index, which is used to compare the relative quality index and the early warning quality index; the early warning module is lower than the early warning quality index when the relative quality index is lower than the early warning quality index. an alarm is issued. The invention is constructed in a modular way, not only can detect the quality of products, but also by establishing a relative quality index mathematical model and drawing a relative quality index curve, real-time alarms are issued for product batches below the early warning quality index line , so as to timely guide the adjustment of front-end production process parameters, which has the advantages of quality assessment, real-time early warning, improved yield, and reduced production costs.

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 era of Industry 4.0, the informatization of industrial manufacturing is an inevitable requirement, and each link of production 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. At present, the detection systems on the market only sort qualified or unqualified products, and are optimized in terms of detection efficiency and manufacturing cost, such as Chinese patent applications 201610722201.1 and 201811227797.3. With the rapid development of integrated circuits, improvements in detection efficiency have been limited. The manufacturing cost of the product is only achieved by reducing the manufacturing cost of the detection system, and...
