Problems solved by technology

If the traditional test design method is still needed, a lot of manpower and kinetic energy consumption costs will be wasted, and at the same time, the production line needs to be stopped to debug and design the test dynamic parameters.
On the one hand, this method reduces the production efficiency of mass production, and at the same time, the experimental design method will consume a lot of manpower and kinetic energy consumption costs

Embodiment Construction

[0018] A method for determining and optimizing dynamic parameters in a plasma display manufacturing process, comprising the following steps:

[0019] Step 1. Establish a regression model of important dynamic parameters and yield rate in the plasma display manufacturing process. The specific method is as follows:

[0020] (1) Segment production records in different time periods for three types of dynamic parameters (temperature, humidity, pressure). The specific segmentation methods are as follows:

[0021] 1) Determine the specific time for the product to pass through each piece of equipment during the entire production process;

[0022] 2) Count and record the quantity of products passing through each device and the final quality level of the corresponding products within a set period of time (such as one day or one month);

[0023] 3) Sampling and recording the environmental parameter information of each device, and use this sampling frequency as the basic sampling frequenc...

Abstract

The invention discloses a method for determining and optimizing power parameters in the manufacturing process of a plasma display screen. A regression relation model of the important power parameters and yield in the manufacturing process of the plasma display screen is established by utilizing the historical data of the manufacturing process and the importance degree influencing the quality of a plasma display screen product is reflected by utilizing a regression coefficient, so that important power parameter items which need to be subjected to management and control reinforcement with emphasis are determined and a power parameter control strategy for promoting the total yield or the single-process yield is found. The method has the active effects that time and resource cost which are consumed in a manner of repeatedly carrying out testing design and verification are saved and direction accuracy on the aspects of power parameter control items and the control range is promoted; and moreover, the aim of continuously and spirally promoting the yield of the plasma display screen can be fulfilled and the rejection rate in the manufacturing process is indirectly reduced. Meanwhile, the method disclosed by the invention cannot be related to the interruption of production of a production line, so that online dynamic determination and regulation management of the power parameters of the manufacturing process are implemented.

Description

technical field [0001] The invention relates to a data mining technology for the characteristics of the manufacturing process of a plasma display screen, in particular to a method for determining and optimizing dynamic parameters in the manufacturing process of a plasma display screen. Background technique [0002] The dynamic parameters of the plasma display manufacturing process directly affect the final quality level of the plasma display. In the past, the experimental design and repeated verification during the construction period were used to determine the dynamic parameter control items and parameter value ranges in the plasma display manufacturing process. With the expansion of production planning and 7*24 hours of uninterrupted mass production, the continuous re-optimization of power parameters will also support the improvement of the quality of the manufacturing process and the reduction of manufacturing costs. It is necessary to stop the production line and carry o...
