Description

Technical Field

[0001] This application relates to the field of touch screen technology, specifically to a method and apparatus for manufacturing a UV-type touch screen. Background Technology

[0002] Touchscreens, as a core interactive component of modern electronic products, are widely used in smartphones, tablets, automotive displays, and other fields. With the continuous upgrading of market demands, the functional complexity and precision requirements of touchscreens have significantly increased, posing numerous challenges to their manufacturing technology. Current touchscreen manufacturing processes typically employ roll-to-roll production, achieving structural and functional integration through multi-layer composites. During touchscreen production, key processes such as conductive silver circuit printing, laser etching, and film cutting require high parameter precision. Traditional equipment struggles to achieve precise control of these parameters, leading to significant fluctuations in product quality and affecting yield. In traditional production methods, equipment often operates independently, lacking unified collaborative control mechanisms, which can easily result in process misalignment or discontinuous flow, increasing defect rates and production costs. Existing production processes lack real-time monitoring and dynamic adjustment capabilities, resulting in low response efficiency and difficulty in meeting the demands for high-efficiency, low-loss production.

[0003] Therefore, in the current touch screen manufacturing technology, there are technical problems such as the difficulty in accurately and collaboratively controlling the process parameters of the core manufacturing process and the lack of dynamic monitoring and adjustment mechanisms, resulting in low touch screen process precision, unstable product quality and low production efficiency.

[0021] This application provides a method for manufacturing a UV-type touchscreen, such as... Figure 1 As shown, the method includes:

[0022] Step S100: Identify the production work order of the target touch screen and determine the production process based on the characteristics of the touch screen, wherein the characteristics of the touch screen include structural characteristics and performance characteristics, and the production process is a roll-to-roll multilayer composite process.

[0023] Preferably, identifying the production work order of the target touchscreen and determining the production process based on the touchscreen's characteristics refers to clarifying the production requirements through its production plan or production task order (work order) according to the specific needs of the target touchscreen, and further selecting a suitable manufacturing process based on the touchscreen's characteristics. Specifically, the production work order of the target touchscreen is a production planning document that details the specifications, performance requirements, and production quantity of the touchscreen to be produced. By identifying the work order, the design requirements of the target touchscreen can be obtained, such as the touchscreen's size, material, touch method (capacitive or resistive), transparency, conductivity, flexibility, and other key parameters. Touchscreen characteristics include structural characteristics and performance characteristics. Among them, structural characteristics include the touchscreen's hierarchical structure and physical composition, such as the cover film. The flexible touchscreen consists of several layers, including a film, a transparent conductive layer, a substrate layer, a protective layer, an optical adhesive, and the thickness, flexibility (bendability of the flexible touchscreen), and surface treatment processes (such as anti-fingerprint coating). Performance characteristics include touch response speed, transparency, resistance, conductivity of the conductive silver circuit, laser etching precision, optical performance (transmittance, reflectivity), and mechanical strength. The production process refers to a roll-to-roll (R2R) multilayer composite process. Roll-to-roll production is a continuous manufacturing process that unfolds the flexible substrate from a roll and rolls it into a finished roll through multiple production processes. Multilayer composite refers to the process of stacking different functional layers one by one through multiple processes to form a complete touchscreen structure.

[0024] Step S100 further includes step S110, identifying the characteristics of the touch screen and determining the modified features; step S120, interactively initializing the process, optimizing the modified features based on process relevance, and determining the optimized process; step S130, segmenting the optimized process to obtain the production process.

[0025] Preferably, the structural characteristics (such as the material type, thickness requirements, and mechanical properties of the multilayer film), functional characteristics (such as light transmittance, surface conductivity, anti-reflective properties, and anti-fouling ability) and appearance characteristics (such as film gloss and surface smoothness) of the target touchscreen are collected to identify touchscreen characteristics. Then, the modification characteristics are determined. That is, based on the above characteristics, the performance of the touchscreen is enhanced by adjusting or adding functional layers through specific processes. For example, anti-fouling treatment of the film surface, hydrophobic and oleophobic coating treatment is applied to the film surface to improve anti-fouling ability and make the touchscreen surface easy to clean; functional layers are added, such as optical enhancement layers (such as anti-glare layers or anti-reflection layers), hardening layers to improve surface scratch resistance, and blue light blocking layers or infrared shielding layers to optimize the optical performance and security of the screen.

[0026] Preferably, the initial interactive process design refers to selecting the optimal combination of multiple alternative processes based on the modified characteristics of the touchscreen, and conducting experimental adjustments. For example, anti-fouling treatment includes plasma surface modification and solution dipping; functional layer deposition includes physical vapor deposition (PVD) and chemical vapor deposition (CVD); and printing methods include screen printing and inkjet printing. Regarding process correlations (the influence and mutual constraints between different processes), the specific implementation process of the modified characteristics is optimized and adjusted to determine the optimized process. For example, ensuring good adhesion between the anti-fouling coating and the substrate layer, optimizing the stacking sequence when adding functional layers, and avoiding interlayer interference or... Performance degradation; finally, the process is optimized by segmenting the process. Specifically, based on the optimization results, the processing steps are further subdivided into different stages to adapt to the performance requirements of different touch screens and production line conditions. For example, the integrated development and etching process completes the development and etching operations in the same equipment, which is suitable for simple circuit patterns or high-efficiency production needs; the separate development and etching process completes the development and etching processes in different equipment, which is suitable for high-precision or multi-layer composite touch screens. The final touch screen production process includes surface treatment, conductive silver circuit printing, laser etching, film cutting, and inspection and calibration.

[0027] Step S200: For the production process, the element control precision constraint is applied to the core process to determine the control constraint conditions. The core process includes at least the conductive silver circuit printing process, the laser etching process, and the film cutting process.

[0028] Preferably, during the production process, key parameters of the core processes (conductive silver circuit printing, laser etching, and film cutting) are precisely controlled, and corresponding control constraints are determined to ensure product quality and process stability. Specifically, the core production processes of the touch screen include conductive silver circuit printing, laser etching, and film cutting. Conductive lines are formed on the substrate surface through high-precision printing. Laser etching technology is used to precisely trim the silver circuit or conductive film to form a circuit pattern. Each functional layer is cut to a specific size and precisely bonded to ensure the matching of optical and electrical properties between layers. The substrate tension, pattern accuracy, composite position, and superposition effect are monitored in real time to ensure processing quality and effectively support high-precision and high-efficiency touch screen manufacturing. The conductive silver circuit printing process refers to forming a high-precision conductive silver circuit pattern on the surface of the touch screen substrate using methods such as screen printing or inkjet printing. Control constraints include ink layer thickness (the thickness of the silver paste coating), pattern resolution (the resolution of the circuit and the clarity of the pattern), printing accuracy (the positioning error of the silver circuit on the substrate), and drying and curing conditions (adjusting temperature and time parameters to optimize the conductivity and adhesion of the silver circuit). The laser etching process refers to using laser etching technology to perform high-precision patterning processing on the conductive layer or substrate, used to refine the conductive silver circuit or form a circuit structure on the conductive film. The control constraints include laser power (laser power output), etching path accuracy (the movement trajectory and speed of the laser etching head), etching depth, and thermal effect control (the heat generated by the laser during etching). The film cutting process refers to cutting the completed touch screen functional layer to a specified size while ensuring smooth edges without gaps. The control constraints include cutting accuracy (cutter head positioning accuracy), edge quality (flat and burr-free cutting edges), tension control (adjusting the tension between rolls of substrate to avoid substrate wrinkles or misalignment during cutting), and repeatability error (reducing positioning errors in multiple cutting processes).

[0029] Step S200 further includes step S210, setting a relationship table between control stability and control accuracy, wherein the control accuracy is the adjustment scale under the current process accuracy; step S220, traversing control elements, combining historical control records, mining control fluctuation trends, and determining the stability coefficient of control elements; step S230, identifying the stability coefficient, traversing the relationship table for matching, and determining the matching control accuracy; step S240, superimposing the matching control accuracy and the element process accuracy, and integrating them as the control constraint condition.

[0030] Preferably, control stability reflects the degree of parameter fluctuation during process control. It is typically quantified through statistical analysis of historical data, including fluctuation range and mean deviation. For example, high stability indicates a small parameter fluctuation range and relatively stable process control. Control precision refers to the smallest unit (adjustment scale) that a process parameter can be adjusted within the currently set precision range. For instance, the printing thickness adjustment precision is ±0.01mm. If a certain control parameter or element is easily affected by environmental vibrations, and the impact is significant, then the amplitude is increased based on the current precision standard to provide higher precision for production constraints, ensuring that even with some control fluctuations, the actual process remains within normal quality standards. A mapping table is established based on different stability levels (e.g., high, medium, low) and corresponding control precision, for example:

[0031] Control stability level Recommended control precision Permissible fluctuation range High stability +0.01mm +0.02mm Medium stability +0.03mm +0.05mm Low stability +0.05mm +0.1mm

[0032] This relationship table is used to dynamically match control precision during the production process, avoiding excessively high precision adjustments under low stability conditions that could lead to increased process fluctuations or wasted adjustment resources under high stability conditions.

[0033] Preferably, control elements refer to key parameters that need to be precisely controlled during the production process, such as the thickness of conductive silver circuit printing, laser etching depth, and the positioning accuracy of the film cutting head. By traversing the control elements and combining them with historical control records (such as parameter adjustment records, deviations between actual and target values, and fluctuations), the control fluctuation trend is explored. That is, the fluctuation pattern of control elements in historical data is analyzed, such as whether there are periodic fluctuations (e.g., equipment wear leading to decreased accuracy) or whether they are affected by external factors (e.g., temperature and humidity changes affecting the thickness of conductive silver circuit printing). Then, the stability coefficient of the control element is determined. Specifically, based on the fluctuation trend, the stability of the control element is calculated using standard deviation analysis (e.g., values ​​between 0 and 1, where 1 is completely stable and 0 is extremely unstable). Finally, the stability coefficient is identified, and the control elements are traversed... The control precision is determined by matching the relationship table. For example, if the stability coefficient is 0.8 (high stability), the matching control precision is ±0.01mm; if the stability coefficient is 0.4 (medium stability), the matching control precision is ±0.03mm. The matching control precision is then combined with the process precision (the process's own set precision, such as the design tolerance range of ±0.02mm for the thickness of the conductive silver circuit printing) as the final control constraint. This constraint is used to adjust the parameter range during production, considering both process requirements and control stability. For example, if the matching control precision is ±0.01mm and the process precision is ±0.02mm, the final control constraint after superposition is ±0.015mm (a comprehensive value obtained through weighted calculation).

[0034] Step S300: Add a main console and connect a single-threaded device group in series to program the control constraints and the production process, and construct a programmable gate array, wherein the programmable gate array is built into the main console.

[0035] Preferably, a main control console is added and connected in series with single-threaded device groups to program the control constraints and production processes. This involves constructing a programmable gate array (PGA) through a combination of hardware and software to achieve centralized management and intelligent control of the entire touchscreen production process. Specifically, the main control console is the core control node of the entire production line, used to centrally manage and coordinate the operating status, process parameters, and flow control of multiple production devices. It can collect sensor data (such as temperature, pressure, speed, tension, etc.) in real time, analyze the process status, and uniformly schedule and optimize production processes, avoiding process misalignment or inefficiency caused by independent equipment operation. Single-threaded device groups refer to groups of devices arranged in sequence during the touchscreen manufacturing process, including conductive silver circuit printing equipment, laser etching equipment, and film cutting equipment. While the processes of each device group are continuous in time and flow, the devices themselves operate independently. By connecting the single-threaded device groups in series through the main control console, the operating status and process parameters of each device are synchronized, avoiding operational disconnects or process conflicts between devices. Simultaneously, the operating sequence and interval time of the devices are dynamically adjusted, transforming the traditional decentralized equipment management model into a centralized, programmed collaborative operation, improving the overall efficiency of the production line.

[0036] Preferably, production process programming refers to programming and embedding the control elements of the production process (such as the ink layer thickness of conductive silver circuit printing, the path accuracy of laser etching, and the size requirements of film cutting) into the main control console to achieve automated management of each process. Specifically, control constraints (such as equipment parameters, operating speed, and accuracy requirements) are transformed into program logic, and the flow sequence of the production process is defined in a programmatic way, so that the production line can automatically adapt to different touch screen characteristics, achieving efficient automation and stabilization of the touch screen production process. Programmable Gate Array (FPGA) is a reprogrammable hardware logic circuit used to achieve efficient parallel computing and real-time response control. It is suitable for complex production line logic and high-precision process control. Specifically, FPGA can quickly process real-time data from various equipment groups, such as sensor signals and process parameter feedback. The logic control program of the production process is embedded in the FPGA, and low-latency, high-reliability process control is achieved through hardware. The FPGA has embedded dynamic adjustment algorithms to quickly adjust equipment operating parameters (such as tension and speed) based on deviations monitored in real time during the production process.

[0037] Step S300 further includes step S310, configuring programmable blocks, wherein the programmable blocks correspond one-to-one with the production process; step S320, based on the production process and the control constraints, converting and determining the logic program and initializing the programmable blocks, and based on the serial position relationship, combining the programmable blocks to determine the first programmable control array.

[0038] Preferably, multiple programmable blocks are configured, each corresponding to a production process, used to manage and execute the control logic of that process. The programmable blocks can be hardware logic units (such as FPGA logic modules). Each block encapsulates parameters related to the production process, logic control rules, and real-time adjustment logic. Then, based on the specific requirements of each production process (such as the ink layer thickness requirement for conductive silver circuit printing, or the path accuracy requirement for laser etching), combined with dynamically adjusted control constraints (such as the final parameter range calculated based on the stability coefficient), the process requirements and control constraints are converted into a programmable logic language (such as VHDL or Verilog) to generate the corresponding control program. For example, the logic program for conductive silver circuit printing may include determining the ink layer thickness. If the layer thickness is within the target range, and if it is outside the range, adjust the printhead movement speed and ink output. Initializing the programmable block involves loading the generated logic program into the corresponding programmable block, enabling it to execute the corresponding process control. According to the production process sequence, the programmable blocks are connected to form a complete production control chain. The programmable block for the conductive silver circuit printing process is responsible for controlling the printing path and ink layer thickness, the programmable block for the laser etching process is responsible for managing the etching accuracy and depth, and the programmable block for the film cutting process is responsible for adjusting the size and cutting path. The blocks are logically linked according to the process sequence to form the overall control logic, thereby determining the first programmable control array, realizing seamless connection between production processes, and ensuring the continuity of control logic.

[0039] Step S300 further includes step S330, setting a dynamic monitoring target, wherein the dynamic monitoring target is determined based on the three-in-one determination of transmission-tension-alignment; step S340, determining boundary conditions based on the target deviation threshold based on the dynamic monitoring target; and step S350, constructing a second programmable monitoring block for the dynamic monitoring target and the boundary conditions.

[0040] Preferably, the dynamic monitoring target is determined based on a three-in-one approach of conveying, tension, and alignment. The dynamic monitoring target is a key parameter that needs to be monitored and controlled in real time during the production process to ensure the stability and accuracy of production. Among them, conveying refers to the conveying state of materials or substrates during the production process, including the stability of conveying speed, position, and conveying path. The monitoring target is to ensure that the material does not deviate or stop during the conveying process, and that the conveying speed is uniform and synchronized with the production process. Tension refers to the tightness of the substrate in roll-to-roll production. Excessive tension may cause the material to break, while insufficient tension may cause wrinkles or inaccurate positioning. The monitoring target is to ensure that the substrate tension is always kept within a preset range. Alignment refers to the precise alignment between multilayer functional films or circuit patterns. Especially when it involves conductive silver circuit printing, laser etching, and other processes, the alignment accuracy is particularly important. The monitoring target is to ensure that the processing positions of different processes are accurate and to avoid superimposed deviations.

[0041] Preferably, based on the dynamic monitoring target, boundary conditions based on the target deviation threshold are determined. The target deviation threshold refers to the maximum range within which the monitored target parameter is allowed to deviate from the set value during dynamic monitoring. Exceeding this range will trigger an alarm or automatic adjustment. For example, the conveying boundary condition allows a conveying speed deviation of ±5% (e.g., if the set speed is 1 m / s, the deviation range is 0.95 m / s to 1.05 m / s), and an allowable position offset of ±0.5 mm. The tension boundary condition allows a tension deviation of ±2 N (e.g., if the tension set value is 20 N, the allowable range is 18 N to 22 N). The alignment boundary condition is a pattern alignment deviation of ±0.1 mm (e.g., for high-precision machining requiring ±0.05 mm). By setting the boundary conditions with deviation thresholds, it is possible to determine whether the state of the production process is normal. A second programmable monitoring block is constructed for the dynamic monitoring target and boundary conditions. This second programmable monitoring block is a logic module designed for the dynamic monitoring target, used to analyze monitoring data in real time and trigger control commands.

[0042] Step S300 further includes step S360, determining the misalignment vector based on the alignment monitoring deviation; step S370, determining the linear relationship between the misalignment vector and the control parameters, and determining the reset function, wherein the linear relationship includes a parameter control relationship and a time limit relationship, and the time limit relationship constrains the defective product jump amount; step S380, constructing a third programmable control block based on the reset function; and step S390, integrating the first programmable control array, the second programmable monitoring block, and the third programmable control block to generate the programmable gate array.

[0043] Preferably, in the composite process of roll production, if a misalignment error exists in one step, subsequent steps will all have problems based on program control, and the entire roll will have errors. Therefore, if a misalignment is detected, the subsequent steps can be aligned and adjusted according to the adjustment time limit. For example, if the adjustment takes two seconds, one step per second, the reset of the next step can be ensured through adjustment. Then, the current and next processed products are marked as defective. Specifically, high-precision monitoring equipment (such as visual inspection, laser alignment sensors, etc.) is used to capture the difference between the actual position and the target position as the alignment monitoring deviation, such as the translation and rotation error of the position. The deviation is calculated through the difference and described in vector form to determine the misalignment vector. Then, the linear relationship between the misalignment vector and the adjustment parameters is determined, that is, a linear mapping relationship between the misalignment vector and the adjustable parameters (such as motor speed, position control signal, etc.) is established. This includes the parameter control relationship between the adjustment parameters (such as servo motor speed, moving platform step value) and the deviation value, as well as the time limit relationship (defining the time constraint of adjustment to avoid the increase in the number of defective products due to adjustment delay). Combining the parameter control relationship and the time limit relationship, the reset function is determined to calculate the adjustment amount.

[0044] Preferably, a third programmable control block is constructed based on a reset function. This block is a logic control module used for real-time correction of misalignment deviations. It adjusts parameters according to the reset function. Specifically, the third programmable control block receives monitoring data from the second programmable monitoring block, extracts the deviation vector, calculates the correction amount based on the input deviation vector and the equipment's control parameters, and calls the actuators of the production equipment (such as stepper motors or servo motors) to achieve real-time position adjustment, tension regulation, or speed compensation. After correction, the deviation is monitored again to form a closed-loop control, ensuring the adjustment is in place. The first programmable control array, the second programmable monitoring block, and the third programmable control block are integrated to form a programmable gate array (PGA) to achieve highly integrated and automated production control, realize closed-loop control in the production line, ensure seamless connection between dynamic monitoring, process adjustment, and flow control, and provide high-response speed and low-latency real-time control capabilities.

[0045] Step S400: Assist the programmable gate array in the manufacturing and control of the target touchscreen, wherein the control dimensions include mainline processing, dynamic monitoring and misalignment adjustment.

[0046] Preferably, a programmable gate array (FPGA) works in conjunction with the main control console to achieve precise control and real-time optimization of the entire touchscreen production process. Specifically, the manufacturing process of the target touchscreen is controlled based on three dimensions: mainline processing, dynamic monitoring, and misalignment adjustment. Mainline processing is the core process of touchscreen manufacturing, including the processing from substrate unfolding and functional layer stacking to the final finished roll material. It covers key processes such as conductive silver circuit printing, laser etching, and film cutting. Specific control includes process logic control, equipment parameter synchronization, and quality control. Among these, process logic control ensures that each processing step is strictly executed according to the preset process flow. To avoid omissions or errors in the process sequence, ensure accurate material flow between each process, and prevent docking problems in intermediate links; equipment parameter synchronization refers to dynamically adjusting the roll-to-roll substrate running speed and tension parameters to match the cycle time of each process. By programmatically managing the key parameters of each piece of equipment (such as ink layer thickness of the printing press and laser etching power), the consistency of the overall process is improved; quality control ensures the precise alignment of each functional film layer with the substrate during superposition, avoiding the impact of superposition misalignment on the performance of the final product. During the main processing, anomalies are adjusted through real-time data feedback, ensuring the smooth execution of the process flow and the coordination of equipment operation.

[0047] Preferably, dynamic monitoring refers to real-time detection and data collection of all key parameters and operating statuses during the production process to promptly detect and respond to anomalies. This includes multi-dimensional data acquisition, real-time feedback mechanisms, and big data analysis. Specifically, multi-dimensional data acquisition refers to dynamically collecting key process parameters, such as substrate tension, temperature and humidity, and equipment operating status (laser etching head trajectory deviation, film cutting head position accuracy, etc.), through built-in sensors and monitoring modules. The real-time feedback mechanism immediately feeds back the abnormal data to the programmable gate array when a parameter is detected to deviate from the preset range (such as substrate offset exceeding the threshold or printing thickness exceeding the tolerance range). The abnormal data is then fed back to the programmable gate array, and the equipment operating parameters are adjusted or an alarm signal is issued through logic calculation. Big data analysis refers to building a production model by collecting and analyzing historical monitoring data to predict potential anomalies and adjust process conditions in advance. Through real-time monitoring and rapid response, the scrap rate caused by anomalies in production is reduced.

[0048] Preferably, misalignment adjustment refers to the rapid detection and correction of misalignment issues in equipment or processes during multi-process linkage, ensuring stable production line operation. This includes equipment misalignment detection, automatic adjustment mechanisms, and process adaptive adjustment. Equipment misalignment detection involves using high-precision vision inspection systems or displacement sensors to monitor the operating status of each piece of equipment and the positioning of the workpiece in real time. Common misalignments include misalignment between the silver printing layer and the laser etching layer, and film cutting position offset. Based on the rapid response capability of programmable gate arrays, when the misalignment deviation exceeds a set threshold, the position or operating parameters of relevant equipment can be adjusted in real time. For example, adjusting the tension of the winding equipment can correct substrate offset, and controlling the position of the film cutting head through a servo motor can correct cutting errors. Process adaptive adjustment refers to automatically optimizing the misalignment threshold and equipment response speed by combining historical misalignment data and current production parameters, improving misalignment adjustment efficiency. The adjusted parameters are synchronized to the main control console in real time for subsequent process correction, enhancing the ability to quickly detect and adjust misalignment issues in multi-process linkage, thereby significantly improving the quality and efficiency of touch screen production.

[0049] Step S400 further includes step S410, simulating the touchscreen electric field, performing touchscreen current flow test and touchscreen response calculation, and determining touchscreen response data, wherein, through the target touchscreen, a surface coupling capacitor is generated on the touchscreen to promote current flow; step S420, performing surface image acquisition and recognition detection to determine defect detection data; step S430, generating a quality inspection report based on the touchscreen response data and the defect detection data; step S440, setting a preset frequency, mining common defects based on the quality inspection report, and using this information to guide the manufacturing management of the target touchscreen.

[0050] Preferably, the simulated touchscreen electric field refers to generating an electric field distribution model of the touchscreen based on the working principle of capacitive touchscreens. This model is achieved by simulating the position, pressure, and shape of different touch points on the touchscreen surface. The changes in surface coupling capacitance generated by the touchscreen are used to simulate the current changes when a user touches the screen, thus testing the current flow performance of the touchscreen and ensuring that the screen can respond quickly and accurately when touched. Touchscreen response calculation refers to calculating the response time, response accuracy, and signal strength of the screen when touched at different locations, which are used as touchscreen response data. Here, response time is the time interval between the touch operation and the screen signal output, signal strength is the amplitude of the change in coupling capacitance near the touch point, and signal uniformity is the consistency of touch signals in different areas. Then, a high-resolution camera or optical scanning device is used to perform a comprehensive scan of the touchscreen surface, capturing images of the screen surface. Computer vision techniques (such as image segmentation, feature extraction, and defect recognition) are then used to process and analyze the acquired images to determine defect detection data, including the location and type of defects. Information such as the severity of defects is combined with touchscreen response data and defect detection data to generate a quality inspection report reflecting the overall quality of the touchscreen. This report includes touchscreen performance indicators, defect indicators (number of surface scratches, conductive circuit defects, proportion of optically uneven areas, etc.), and the judgment result on whether the touchscreen is qualified. A preset frequency is set, meaning that a certain proportion of touchscreens produced in a batch are subjected to quality inspection. Common problems in mass production are analyzed. Specifically, by analyzing the defect data in the quality inspection report, frequent defects and their possible causes are identified. The frequency and distribution patterns of each defect are statistically analyzed. Combined with the production process, possible sources of common defects are traced, such as equipment errors, material problems, or improper process parameter settings. Finally, based on the analysis results of common defects, the production process is adjusted and optimized to improve the monitoring accuracy of specific areas (such as areas with high-frequency defects), and process parameters (such as printing thickness, laser etching power, bonding pressure, etc.) are adjusted to reduce defect generation, thereby optimizing the production process and management procedures and improving the overall product quality.
