Description

Technical Field

[0001] The present invention relates to the technical field of electronic assembly, and in particular to a data transmission and control system for electronic assembly manufacturing and a method of using the system. Background Art

[0002] Integrated data transmission and control for electronic assembly manufacturing of printed circuit board assemblies mainly refers to the structured design and application of process parameters of printed circuit board assemblies. The process parameters in the process files play an important guiding role in the assembly of electronic products.

[0003] The application of process parameters in traditional process design has the following problems: (1) Traditionally, each process technician has to search the manual one by one according to the component BOM (Bill Of Material) to collect relevant assembly process information and determine the process parameters. The process technician uses this as the operating requirements for the operators and writes them down in the process content. However, the collection and writing of component process parameter information is repetitive work, which seriously wastes human resources and has low parameter collection efficiency. (2) Since there are many types of components to be operated in each process, in order to avoid omissions, process personnel solidify the operation methods of various types of components in the visual process standards. The process documents only quote the visual standard requirements and no longer specify the specific operation methods of specific components one by one, resulting in unclear and unintuitive process guidance for operators; (3) The risk operation process requirements of risk components in the process documents are hidden in the content of large process sections and are not prominent enough. Due to the limitations of process engineers, the risk operation process requirements of risk components have poor consistency and are prone to omissions, which leads to quality problems in the product manufacturing process.

[0004] (4) Each target product has a working time, and the traditional working time is calculated by process personnel by adding up the working time for each component, which is time-consuming and labor-intensive, and has low accuracy.

[0005] With the continuous development of electronic assembly, the complexity and integration of printed circuit board assemblies are getting higher and higher, and the types of components involved are increasing. The corresponding process parameters and process requirements are becoming more and more complicated. The application of traditional process parameters is insufficient, and the method of writing them one by one is relatively backward. It has become increasingly difficult to meet the process parameter requirements of a large number of printed circuit board assemblies.

[0006] The solution of the present invention is to improve the traditional method of applying process parameters in view of the above problems. Summary of the invention

[0007] In view of the above problems, the purpose of the present invention is to provide a data transmission and control system for electronic assembly manufacturing and a method of use, so as to solve the problems in the existing process design such as excessive reliance on manual experience, poor repeatability, complexity and consistency in process parameter design and application, lack of prominent risk operation reminders and easy omissions, repetitive labor in working hour calculation and low efficiency.

When performing process design, the system automatically generates reminder items applicable to the current process from the processes; The process attribute library automatically generates requirements according to the process report, adds the attribute information of baking time, baking temperature, tinning method, lifting height, and component working hours after the corresponding components, printed circuit boards, and microstrip boards, and then enters it into the process manufacturing management MPM module. After determining the process, various process reports will be automatically generated according to the rules and automatically matched to the relevant processes; The risk operation library automatically generates requirements based on risk operation precautions, adds reminders and process name attribute information after the corresponding components, and then enters them into the process manufacturing management MPM module. After the process is determined and the current components are assembled to the current process, all reminders and precautions in the current process are automatically generated according to the rules and automatically matched to the process.

[0011] Furthermore, the process manufacturing management MPM module is used for the management of product BOM and part of the process parameter knowledge module, and saves the product working hours, process reports and risk operation reminders generated by the data transfer and control module.

[0012] Furthermore, the data transmission and control module is used to read the product BOM provided by the process manufacturing management MPM module and realize the automatic calculation of the working hours of the printed circuit board assembly product, the automatic generation of process reports and the automatic reminder of risk operations through the rule judgment of the process parameter knowledge base module, and return the results to the process manufacturing management MPM module, thereby forming the working hours, process reports and risk operation reminders suitable for the printed circuit board assembly product.

[0013] Furthermore, the data transmission and control module includes a working time calculation unit, a variable maintenance unit and a risk operation reminder unit; The working time calculation unit is used to calculate the working time of the printed circuit board assembly product according to the working time attributes in the process attribute library and the working time calculation rules, and then write the working time result back to the working time column of the printed circuit board assembly product; The variable maintenance unit is used to maintain the process parameters related only to the product characteristics of the printed circuit board assembly, and in the loading part tab of the process, the information of the loading part that needs to maintain the variable information is maintained, and then the maintained information is summarized in the variable maintenance information tab, and finally, the process report is generated in accordance with the report rules and transmitted to the process manufacturing management MPM module; The risk operation reminder unit is used to provide risk operation reminders for risky components in different electrical installation processes, and accurately push reminder precautions to corresponding processes based on the risk operation library combined with risk operation reminder rules.

[0014] Furthermore, the process reports include: "Printed Circuit Board Pre-baking Table", "Component Pre-baking Table", "Surface Mount Components Tinning Method Table", "Plug-in Components Tinning Method Table", "Plug-in Component Lifting Height Table", "Fasteners Tightening and Anti-loosening Table", and "Electrical Connector Lap Resistance Table".
