Problems solved by technology

[0003] In the traditional method, the increase rate of PCB orders is mainly predicted by the production scheduler based on the experience to evaluate the difficulty of PCB manufacturing. This method has a lot of subjectivity, which easily leads to inaccurate predictions and takes a long time to predict

Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0031] The influencing factors of PCB addition rate mainly include two aspects. One aspect is that affected by the scrap rate, certain scrap situations will inevitably occur during PCB processing. The reasons for product failure include subjective factors and objective factors. Among them, subjective factors mainly refer to the scrapping caused by unreasonable artificial design process and operational errors, etc., which can generally be traced directly to the responsible person. Objective factors are mainly due to the fact that the product requires many processing para...

Abstract

The invention relates to a method and device for establishing a calculation model of PCB additional feeding rate. The method comprises following steps: extracting relevant parameter data of PCB additional feeding rate and screening the relevant parameter data to obtain initial parameter data; analyzing the data distribution characteristics of initial parameter data and evaluating the correlation and significance between initial parameter and PCB additional feeding rate according to initial parameter data to obtain the global distribution information and the global change rule information including each initial parameter, as well as the global prediction results of correlation factor and significance factor; by regression analysis based on the initial parameter data and the overall prediction results, obtaining the final retention parameters and parameter factors thereof related to PCB additional feeding rate; determining the PCB additional feeding rate calculation model according to the final retention parameters and the parameter factors. By means of the PCB additional feeding rate calculation model established in the invention, the prediction of PCB order additional feeding rate can be achieved, the predicted efficiency and accuracy of PCB order additional feeding rate can be increased.

Description

technical field [0001] The present invention relates to the technical field of PCB, in particular to a method and device for constructing a calculation model of PCB addition rate. Background technique [0002] The PCB (Printed Circuit Board, printed circuit board, also known as printed circuit board) industry has the characteristics of many sources of customers for PCB boards and strong order randomness, and PCB products have strong personalization, many production parameters and process characteristics, and high precision requirements. advanced features. These characteristics lead to scrapping in the PCB production process. Therefore, PCB companies generally make appropriate multi-inputs when PCB materials are fed, that is, additional inputs, to make up for the losses caused by scrapping. At the same time, PCB generally cannot be directly processed according to the size of the finished board, and it needs to be in the form of jigsaw puzzles. When the delivery quantity divi...
