Analysis of Implementation Characteristics of PDM/PLM Projects in Electronic Design and Manufacturing Industry

In recent years, domestic manufacturing companies have paid more and more attention to PDM/PLM technology management informationization. PDM/PLM technology has been well implemented in different industries, and the application of PDM/PLM has gradually become larger. On the one hand, PDM/PLM mechanical design and manufacturing enterprises are well received and well-applied. These industries mainly focus on mechanical parts, and they need to manage products such as product technical data, BOM, workflow, engineering projects and process manufacturing. The management models of each enterprise are basically the same, but in different industries, the focus needs to be different. For example, the large-scale power generation equipment industry mainly focuses on the complex single BOM and data management of the unit, and the automotive industry mainly focuses on the configuration management of automobile products. And order management, etc. Another application of PDM/PLM is the electronic design and manufacturing industry. The electronic design and manufacturing industry is different from the mechanical design and manufacturing industry in many businesses. Therefore, PDM/PLM is implemented in the electronic design and manufacturing industry. The focus of the implementation of the machinery manufacturing industry is also slightly different. The following describes some of the implementation key and implementation experiences of the electronics industry PDM/PLM project.

I. Analysis of the implementation characteristics of PDM/PLM projects in electronic design and manufacturing industry

First of all, there are many product lines in the electronic design and manufacturing industry, and there are many product line series, the product life cycle is short, and there are many stages in the development of new products. Electronic design and manufacturing industry products are generally composed of mechanical structure parts, hardware parts and software parts, and the products involve multidisciplinary and multi-field. In the product phase, a large number of engineering changes due to cost reasons, how to manage various changes, and how to implement version control (including versions between hardware and software) have become the focus of PDM/PLM implementation in the electronic design and manufacturing industry. Secondly, most of the electronic design and manufacturing industries are mainly research and development. The whole product system consists of market chain, R&D chain and supply chain. The R&D team and R&D management of the enterprise are difficult. How to establish a good R&D management system for new products The development provides ideas, approaches and organizational guarantees, enabling electronic design and manufacturing companies to develop good products with maximum probability is another focus of PDM/PLM implementation.

Second, electronic design and manufacturing industry product line management

The electronic design and manufacturing industry products are mainly composed of an institutional part, a hardware part and a software part. For structural parts, the structural level is relatively simple. Generally, the number of parts in a single product structural part is not much, and the design of the structural part is mainly the peripheral part of the product. For hardware design, ECAD (such as Protel, Cadence, etc.) is mainly used for circuit schematic and printed circuit schematic design. The main work content is the design of schematic and printed board graphics. Due to the large number of new components to be selected during the hardware design process, component selection, certification, and auditing need to be effectively managed. In addition, the hardware design also needs to consider the version correspondence between the hardware and the corresponding sintering software. For software design, mainly use various programming software and assembly software to develop software that needs to be burned in hardware.

Therefore, there are many product lines in the electronic design and manufacturing industry. Due to the particularity of the products, the products involve multiple disciplines. For the management of the product line, it is necessary to establish a series of product family management models and a unified product line platform by means of the PDM/PLM platform to realize effective management of the product line. The product line management of the electronic design and manufacturing industry mainly includes product series classification management, product technical data, product BOM, version management, electronic component library management, PCB drawing and component assembly location management. In the implementation process, product line management Successful implementation is the focus of the implementation of PDM/PLM in the electronics industry.

Third, electronic design and manufacturing industry structured workflow management

In general, the R&D team in the electronic design and manufacturing industry is large, and the processes involved in the entire R&D process are numerous and the processes need to be refined. Throughout the world, IBM, Boeing, Nokia, DuPont, Cisco, Huawei, Fangtai, Xu Ji Electric and other domestic and foreign companies, in the product development of the integrated product development as the idea, the development process takes a structured workflow. The product structured workflow consists of phases, steps, tasks, and activities. Product development is divided into different phases, each phase is divided into different steps, emphasizing work tasks and activities (such as summary design, detailed design, unit testing, etc.).

Therefore, another focus of PDM/PLM implementation in the electronic design and manufacturing industry is the implementation of product structured workflow. Through the PDM/PLM platform, integrated product development ideas and structured workflows are integrated into the PDM/PLM platform for unified management. Effective, collaborative work mechanism. This part of the implementation requires detailed investigation of the enterprise R&D chain structured workflow and supply chain processes, analysis and optimization of existing processes, customization of form business models and structured models. In the implementation of the promotion process, it is also necessary to gradually promote these processes according to the business.

Fourth, electronic design and manufacturing industry R & D project management

On the basis of structured workflow, the electronic design and manufacturing industry drives product design tasks according to the model of the project. It is considered from the entire R&D management system and is reflected in the project management layer, task execution layer and structured workflow layer. The electronics industry's projects are mainly composed of the following stages.

1) Product development planning stage. The highest decision-making level determines the development direction of new products according to customer requirements and market forecasts. The product research center collects data, prepares new product development plans, and after decision-making discussion, issues product design task books to product development departments, and designates project managers. Responsible for the research and development of new products until the product batch is officially supplied to customers.

2) Design, trial production, testing, testing and finalization stages. From the program design, technical design, trial production, testing, testing to improved design, trial production, and testing, this phase is an iterative process. If the review of the intermediate process cannot be passed, it is necessary to repeat the improvement design, trial production and test until the product identification determines the small batch trial production drawing. For enterprises with large R&D systems, this process is difficult to manage and it is difficult to form a collaborative design process management system.

3) Production technology preparation stage. While improving the design of the sample, some of the components that are sure to be grasped can be prepared in advance for production technology. When the design is improved, the trial production, and the test are completed, large-scale production technology preparation can be carried out after passing the review. It mainly includes process design, design and manufacture of self-made equipment and tooling in the company, matching of equipment ordering and cooperation parts of the company, and procurement of raw and auxiliary materials for production.

4) Small batch trial production stage. A small batch of trial production is carried out after the completion of the production technology preparation phase. On the one hand, small batch trial production should verify whether the process tooling can meet the needs of mass production. On the other hand, various behavior tests should be carried out on the small batch of trial production products to determine whether the product quality and technical level meet the design requirements. After the small batch of trial production, it shall be submitted to the customer for review and approval. After the approval, the technical documents such as products, processes and equipment may be converted into formal production documents after being modified.

5) Mass production stage. The preparation of after-sales service must be completed before the products are put into production in batches, including various technical documents of new products. After the completion of the above-mentioned stages, the prototypes can be produced and mass-produced after confirmation by the customer.

Therefore, in the implementation of PDM/PLM, the overall planning PDM/PLM application and implementation level is required. The first is product product management application level with product line management as the core, followed by project management level with project management as the core. At the application management level, building a project management platform and project evaluation system is the focus of implementation.

V. Material selection management in electronic design and manufacturing industry

Electronic design and manufacturing industry products use a large number of purchased parts, these are mainly electronic components. Since the electronics industry has strict requirements for the selection of new components, it needs to go through several steps such as device primary selection, device certification, device evaluation, and device optimization level identification. Therefore, the material selection management requirements are very high.

In the process of implementing PDM/PLM, it is necessary to establish an effective electronic component library, and also need to consider the unity with the EDA library in ECAD. During the design process, the designer needs to query the effective parts library resources in time, select the materials that meet the conditions, and improve the reuse rate of the materials. If the conditions are not met in the library, the designer creates a new material application form for the new device. Selection and certification audit, after the approval of the certification, the code will be given by a special person, and then released into the effective parts library.

6. Knowledge Resource Management in Electronic Design and Manufacturing Industry
In the process of product development, the electronic design and manufacturing industry will form different knowledge and experience at different stages. These knowledge and experience are valuable assets of the enterprise. Many electronic design and manufacturing industries focus on establishing effective knowledge resources in the process of implementing PDM/PLM. Implementation work. For example, in the product development process, one of the important links is unit testing and system testing. The testing work is mainly done by the testing department. The testing department finds product defects and generally submits product defect sheets and submits them to relevant designers for modification. After the modification is completed, it is verified by the testing department. Finally, these defects are uniformly incorporated into the defect library for management, which provides a reference for subsequent products to reduce errors.

In addition to the above analysis, in the process of implementing PDM/PLM in the electronic design and manufacturing industry, there are still many points to focus on and implement. It needs to be gradually improved and optimized in the implementation process under the overall guiding ideology of overall planning and step-by-step implementation.
