Electronic products have undergone several production steps such as design molding, mechanical assembly and electronic assembly, and complete assembly. In this process, because of the similarity of the design of the circuit, the discreteness of the components and the limitation of the assembly process, the overall result of the final production needs to be debugged, and the technical functions and specifications specified in the design can be achieved. Therefore, the management of the debugging process of electronic products is related to the quality of electronic products.
1 The main content of electronic product debugging Debugging process management must clarify the content of electronic product debugging. If even this is not familiar with or unclear, management is impossible to talk about. The main contents of electronic product debugging are as follows: Reasonable selection and use of the instruments and meters required for debugging; In accordance with the debugging process card, the unit circuit board or the complete machine shall be adjusted and tested strictly; the failures occurring during the debugging process shall be eliminated and the debugging records shall be prepared; To assess whether the product adapts to the environment in which it is used, and to assess the adaptability of the power supply. The content of each stage is different and cannot be replaced by each other, but it is complementary and closely related.
2 Debugging process documentation requirements of electronic products The debugging process of electronic products mainly emphasizes the specific execution process of the debugger. This process is also saved in the form of documents. Debugging technicians should focus on document operability, implement specific items and content of electronic products, test conditions, and some process requirements in testing, such as instrumentation and related precautions, and safety operations. Next, elaborate on the following aspects. The commissioning workbook used in the commissioning process of China Electronics Section 54 has the following features:
1 In view of the particularity of the debugging process, the format requires a more flexible format, but the title bar and signing bar are clearly defined.
2 process name. The names of the operations in the Commissioning Work Instruction Card were unified.
3 Emphasizes the wiring relationship between the equipment and instruments during the commissioning process. In order to improve the operability of the documents, each debugging process is accompanied by a detailed cable connection block diagram, which specifically describes the connection between the debugging equipment and the instrument. The content of the test is compiled. Each debugging process should be divided according to the actual situation, generally can be divided into single or multiple steps, the preparation of each process must be complete, the process must be reasonable, the operation of the order and method of expression must be detailed and accurate.
4 In order to facilitate the production organization, each debugging process should be divided into single or multiple steps according to the actual situation. The preparation of each process must be complete, the process must be reasonable, and the sequence and method of operation must be detailed. accurate.
5 emphasize the use of power in debugging. It is required to specify the various index requirements and power-up sequence of each power supply.
6 Through experience accumulation, it is necessary to continuously provide faults that often appear in the debugging process and give corresponding solutions. To improve the guidance of the debugging process.
7 Screening and stress test process description. It is required that according to the screening conditions, the selected curve should be drawn to clearly and accurately express the test process and the required time, so as to provide reliable data for the planning and arrangement.
8 The format requirements of the debugging records are the same as the requirements of the debugging process. The format requirements of the debugging records also only specify the recorded items. For different products, the format can vary greatly due to the different numbers and nature of the indicators that need to be tested, debugged, and recorded. However, the product design requirements must be given so that the debugging process can directly determine whether the requirements are met, the test data recording area with relatively reasonable layout, and the product maintenance record area.
3 debugging process process management due to the special nature of electronic products, the test site humidity, temperature and electromagnetic environment needs to be tested, regular measurements, to ensure reliable grounding, temperature should be between 15 °C ~ 35 °C, humidity in the 20 ~ 80 %between.
3.1 Enhance debugging Preparation work and static test Before commissioning, we must be familiar with the design documents, mainly including "debugging work instructions" and technical specifications, technical conditions, operating instructions, maintenance manuals and other design documents. Select and prepare suitable instruments and meters according to the requirements of the commissioning work instructions. Make sure that the instrument is in an effective use period; be prepared for the test cables required during commissioning so as not to affect the commissioning progress. To an electronic product to be debugged, it must not be rushed to debug, but must first check the appearance of its glaze check. At the same time, electronic products should also be tested for insulation withstand voltage, and the performance of electrical appliances should be checked. For some electronic products that do not accept high-voltage circuits internally, it is necessary to come up with practical protection measures.
3.2 The main requirements for commissioning records management are truthfulness, effectiveness and completeness. Keep records clean and tidy. Fill in the product serial numbers one by one. Do not forge data. Special emphasis is placed on the maintenance process records in the commissioning process. The quality problems of the device and the quality of the assembly process can often be found during the debugging process. These problems are recorded through maintenance records. Through analyzing and summarizing these records, you can provide decision-making basis for improving the assembly ability and strengthening the device inspection process. . The debug record should show the real state of the product during commissioning and the configuration of the product at the time of outsourcing. The completed records are also sorted, bound, and archived as required to allow traceability of the process after the quality problem has occurred.
3.3 Notes on the debugging process When there is no specific description, the debugging of each performance index should be strictly in accordance with the order and method of process requirements. If the debugging cannot be completed according to the method given in the process, it needs to be reported to the technical personnel in time and it is not written. No changes are allowed before the change notification.
3.4 Summary after debugging After the product debugging is completed, there should be a summary of the debugging process, including the problems encountered in the statistical debugging process and solutions, and to propose changes or improvements based on the actual situation, timely feedback to the design department , Then the design department gives advice and solutions.
3.5 Strengthening inspection In addition to strengthening the requirements for self-inspection, higher requirements are placed on special inspections in the process, not limited to the composite inspection of the inspection program and product specifications provided by the design department, but the laws, regulations, national standards, Military standards and other requirements are as comprehensive as possible, all of them are tested, and the product's safety, availability, fault tolerance, etc. are checked as comprehensively as possible, thereby improving the quality of the product.
4 Conclusion Through the strengthening of document preparation, process recording, inspection, commissioning summary, and daily inspections, the management level of the debugging process of the 54th Institute of CLP has been continuously improved, and the product quality has been improved. Strengthening management not only does not affect the progress, but also leads to a more scientific and detailed schedule management, while reducing the post-sale maintenance work and improving the efficiency of the company.
