[0002] Controlling the inner-layer Yin-Yang laminated board is an important link in the field of electronic manufacturing, especially in the production of high-end electronic products, where its quality and stability are directly related to the overall performance of the product. The inner-layer Yin-Yang laminated board is a special circuit board structure, in which the term "Yin-Yang" is usually used to describe that its front and back sides (or top and bottom layers) have different circuit layouts or component configurations. The design of this stacked board enables the circuit board to use space more efficiently during the manufacturing process, while meeting the complex circuit wiring requirements. Through reasonable management and control, waste in the production process can be reduced, production efficiency can be improved, and the size, shape, and wiring density of the inner layer yin and yang stacked boards can be ensured to meet the design requirements, thereby improving the stability and reliability of the product. Effective management and control can optimize the production process and reduce unnecessary material and labor costs. In the design stage, it is necessary to fully consider the layout and wiring requirements of the components, avoid overly crowded or empty areas, follow relevant industry standards and specifications, ensure design quality and product safety, consider production feasibility and producibility, maintain close communication with the production department, strictly control the quality of raw materials, ensure that the substrate, copper foil and other materials used meet the design requirements, and conduct strict quality inspections on each process during the production process to ensure that the product quality meets the standards. The inner layer yin and yang stacked boards are widely used in communications, medical, aerospace, automotive electronics and other fields. These fields have high requirements for circuit board performance and have certain restrictions on production costs and production cycles. By adopting the inner layer yin and yang stacked board technology, the requirements for circuit board performance and production efficiency in these fields can be met. Controlling the inner layer yin and yang stacked boards is an important link in the field of electronic manufacturing. Through reasonable management and control methods, we can ensure the quality and stability of products, improve production efficiency and reduce production costs. In the future, with the continuous advancement of technology, the inner layer Yin-Yang stacking board technology will play a greater role and make greater contributions to the development of the electronics industry.

[0003] In the manufacturing process of electronic products, the production of the inner layer Yin-Yang stacked plate is one of the key steps. However, when the size of the stacked plate is large, especially when a substrate with a thickness combination of 0.076mm+0.1mm is used, the problem of inconsistent expansion and contraction often occurs due to factors such as material properties and processing conditions. This not only affects the smooth progress of the subsequent pressing process, but may also lead to a decline in product quality and increase production costs. To address this problem, a method for controlling the expansion and contraction of the inner layer Yin-Yang stacked plate is provided. Summary of the invention

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1 to Figure 2 The present invention provides a technical solution: a method for controlling the expansion and contraction of the inner layer in manufacturing the yin-yang laminated plate, comprising the following steps:

[0030] S1. Design circular holes for measuring expansion and shrinkage. Design a circular hole for measuring expansion and shrinkage at each of the four corners of the inner film. These circular holes will serve as reference points for evaluating the expansion and shrinkage of the stacked plate. Determine the main purpose of designing the circular holes for measuring expansion and shrinkage, such as evaluating the expansion and shrinkage of the stacked plate, optimizing production process parameters, etc. Understand in detail the key parameters of the stacked plate, such as material, size, thickness, wiring density, as well as the production environment and test conditions. Design a circular hole for measuring expansion and shrinkage at each of the four corners of the inner film to ensure that the position of the circular hole can accurately reflect the expansion and shrinkage of the stacked plate. Set the diameter and depth of the circular hole according to the measurement accuracy requirements and production conditions. The diameter should usually be large enough so that the measuring equipment can accurately enter and measure, but not too large to avoid affecting the overall performance and structural stability of the laminated plate. The layout of the circular holes should take into account the positioning and fixing requirements during the production process to ensure that the circular holes do not conflict with other components or wiring on the laminated plate. Use computer simulation software to simulate the design of the circular holes, evaluate its feasibility and accuracy in the actual production process, make sample laminated plates, and process circular holes for measuring expansion and contraction on them according to the design. Use high-precision measuring equipment to actually measure the circular holes on the sample laminated plates, record the measurement data, analyze the measurement data, and evaluate the accuracy and effectiveness of the circular hole design. If the data does not meet expectations, return to the design step for adjustment. According to the data analysis results, optimize the design of the circular hole, such as adjusting the position, size or layout. According to the optimized design, improve the production process parameters to improve the expansion and contraction control accuracy of the stacked plate. Submit the optimized design to the relevant departments for review and approval to ensure that the design meets the relevant standards and specifications. The final design drawings and related documents are archived for use in subsequent production and testing processes. Accurate and effective circular holes for measuring expansion and contraction can be designed to provide strong support for the expansion and contraction control of the stacked plate. At the same time, these steps also help to improve production efficiency and product quality and reduce production costs;

[0031] S2, production and measurement, during the inner layer production process, expansion and contraction circular holes are produced on the film according to the design;

[0032] S3. Data analysis and evaluation: Based on the measured data, the relative position between the circular holes is calculated to obtain the standard size data of the Yin-Yang stacked plates, including length, width, thickness, etc. High-precision measuring tools (such as vernier calipers, laser rangefinders, etc.) are used to measure the size of the plates actually produced. Multiple positions of the plates should be considered during measurement to obtain more comprehensive size data. The actual measured plate size is compared with the standard size to calculate the size deviation. The size deviation may include length deviation, width deviation, thickness deviation, etc. Based on the size and direction of the size deviation, the expansion and contraction of the plate is evaluated. The expansion and contraction may include overall expansion and contraction, local expansion and contraction, unidirectional expansion and contraction, etc. Combined with the production process and raw material characteristics, the possible causes of the expansion and contraction of the plate are analyzed. The reasons may include material thermal expansion coefficient, processing temperature, humidity changes, uneven pressure distribution, etc. Alarm thresholds for size deviation and expansion and contraction are set according to production requirements and quality standards. When the actual measured data exceeds the alarm threshold, the alarm mechanism is triggered to prompt the production personnel to pay attention. Based on data analysis The results are used to determine whether the board meets the production requirements and quality standards. For unqualified boards, rework and scrapping should be adopted. According to the reasons for the expansion and shrinkage analyzed, targeted improvement measures should be formulated. The improvement measures may include adjusting the production process parameters, optimizing the selection of raw materials, strengthening the temperature and humidity control, etc. After the implementation of the improvement measures, the board size data is collected again, and the data is analyzed and evaluated. The data before and after the improvement are compared to evaluate the effect of the improvement measures, and the improvement measures are adjusted as needed. A continuous monitoring system for board size and expansion and shrinkage is established to ensure that the data in the production process is real-time and controllable. The monitoring system should include data collection, data analysis, alarm mechanism, improvement measures and other links. The monitoring system should be evaluated and optimized regularly to ensure the accuracy and effectiveness of the monitoring system. According to the changes in production needs and quality standards, the parameters and indicators of the monitoring system should be adjusted in time. The data analysis and evaluation process for the expansion and shrinkage of the inner layer of the yin-yang stacked plate includes data collection, data analysis, data evaluation and decision-making, and continuous monitoring and optimization. Through the implementation of this process, the stability of the board size and processing accuracy can be ensured, and the product quality and production efficiency can be improved;

[0033] S4. Adjust the production process parameters. According to the evaluation results, adjust the production process parameters. The purpose of adjusting the production process parameters is to ensure the stability and controllability of the production process, thereby improving the quality and consistency of the product. By optimizing the process parameters, waste in the production process can be reduced, production efficiency can be improved, and production costs can be reduced. At the same time, reasonable process parameter settings can also help extend the service life of equipment and reduce maintenance costs. By collecting and analyzing production data, the key factors affecting these problems can be identified. For the identified key factors, the relevant production process parameters can be further analyzed. These parameters may include temperature, pressure, speed, time, raw material ratio, etc. Based on the analysis of parameters, an adjustment plan can be formulated to gradually adjust and optimize the relevant parameters. The best parameter combination can be determined by experimental design (such as orthogonal test, response surface method, etc.). After adjusting the parameters, the production process needs to be continuously monitored and the adjustment effect evaluated. By collecting and analyzing new production data, it is verified whether the parameter adjustment has achieved the expected effect. When adjusting the production process parameters, the bearing capacity of the equipment and the skill level of the operator should be fully considered. When adjusting the parameters, the principle of gradual progress should be followed to avoid excessive one-time adjustments that lead to unstable production. During the adjustment process, communication and cooperation with relevant departments and personnel should be strengthened to ensure the smooth progress of the adjustment work. It is necessary to continuously collect and analyze production data, identify problems and formulate corresponding adjustment plans. Through reasonable parameter adjustment, product quality and production efficiency can be significantly improved, bringing greater economic and social benefits to enterprises. Therefore, enterprises should attach great importance to the adjustment of production process parameters and continuously improve and optimize relevant processes and methods;

[0034] S5. Continuous monitoring and feedback. Continuously monitor the position changes of the expansion and contraction holes. If abnormal expansion and contraction is found, timely feedback and adjustment of production process parameters are given. Continuous monitoring refers to real-time monitoring of the operating status of the system or product, capturing various performance indicators and abnormal events. It can help the operation and maintenance team or quality management personnel to understand the health of the system in real time, discover potential problems in time and take measures to intervene, such as CPU usage, memory usage, network traffic, response time, etc. These indicators can reflect the operating efficiency and load of the system, such as system crashes, service interruptions, data loss, etc. These events will have a serious impact on the stability and availability of the system. The performance indicators and abnormal event data of the system or product are collected in real time through monitoring tools, and the collected data are stored in an efficient database for subsequent query and analysis. The stored data is analyzed to generate reports and alarms. When the system detects an abnormality or the performance indicator exceeds the threshold, the monitoring tool will trigger the alarm mechanism and notify the relevant personnel in time to handle it. The alarm method can include email, SMS, instant messaging tools, etc. Alarms are classified and prioritized according to the severity and scope of the problem. High-priority issues should be dealt with first to ensure the stability and availability of the system. The problems found should be recorded and fed back to the relevant teams for repair. You can use an issue tracking system (such as Jira) to record and manage issues to ensure that each issue is handled and tracked in a timely manner. Conduct in-depth analysis of the reported issues to find out the root causes. You can use tools such as fishbone diagrams (Ishikawa diagrams) for analysis and develop specific improvement plans based on the results of the root cause analysis. The improvement plan should include clear goals and implementation steps;

[0035] By designing circular holes for measuring expansion and contraction at the four corners of the inner film and using high-precision measuring equipment for measurement, an accurate assessment of the expansion and contraction of the laminated plate is achieved. The production process parameters are adjusted according to the measurement results, which effectively reduces the expansion and contraction differences between layers and improves the expansion and contraction performance of the laminated plate. Through precise measurement and adjustment, the problem of poor fusion layer of the pressed laminated plate caused by inconsistent expansion and contraction is avoided, thereby improving production efficiency. The position changes of the expansion and contraction circular holes are continuously monitored to ensure that the expansion and contraction of the laminated plate is controlled within an acceptable range, thereby ensuring the stability and reliability of the product.
