Description

Technical Field

[0001] This invention relates to the field of PCB forming process prevention and interception technology, and more specifically to PCB forming process prevention and interception methods, devices, computer equipment and storage media. Background Technology

[0002] The manufacturing process of printed circuit boards (PCBs) is complex, involving multiple processes and sub-processes, typically requiring more than 30 processing steps. For example, the molding process, in addition to the main process of molding the PCB, includes multiple sub-processes such as molding PTH slots, internal slots, PCB set outlines, lead wires, PCB borders, PCB platforms, countersunk holes, large board V-cuts, finished product V-cuts, and beveling. This complex process makes it easy to miss processing steps in actual production, thus affecting product quality and production efficiency.

[0003] Currently, the most common methods for intercepting missed processes in the industry include the following: Work order signature interception: Each batch of boards is equipped with a Lotid work order, and the corresponding process column on the work order requires signature confirmation. After each process is completed, the employee of the next process needs to check whether the previous process has been signed. However, because work orders are easily damaged or missing during the transfer of PCB boards, and production lines often rush to ship boards in order to meet production targets, employees cannot promptly confirm whether each batch of work orders has been signed, resulting in frequent omissions in the process.

[0004] MES system interception: Products are traced by scanning codes through the MES system to intercept missed processes. However, the development cost of this system is high, exceeding ten million yuan for a single system, and it is difficult to implement, which cannot meet the implementation needs of all enterprises and limits its widespread application.

[0005] Report-based interception: This method intercepts missed processes by reviewing production report records. However, it has significant drawbacks. Employees may not record information, record it incorrectly, or even delete records to avoid responsibility when products are defective, rendering the interception ineffective.

[0006] Inspection equipment interception: Interception is achieved through inspection equipment such as final visual inspection machines and hole inspection machines. However, these devices are typically used for finished product inspection and are subject to delays, failing to detect omissions in the processing flow in a timely manner.

[0007] Interception via signage or billboards: Scheduling staff or employees add signage or billboards to confirm the process before transfer. However, this method can only play a supplementary role and cannot fundamentally achieve effective interception.

[0008] In summary, existing methods for intercepting missed processes all have certain limitations and defects, failing to fundamentally solve the problem of missed processes in PCB manufacturing. This affects product quality and production efficiency, increases production costs, and raises the risk of customer complaints. Therefore, there is an urgent need for a technical solution that can eliminate missed processes and missing records / reports, and can adapt to the arbitrary switching of processing sequences in internal sub-processes, in order to meet the production needs of the printed circuit board industry. Summary of the Invention

[0009] The purpose of this invention is to overcome the shortcomings of the prior art and provide a method, device, computer equipment and storage medium for preventing interception during PCB forming process.

[0010] To achieve the above objectives, the present invention adopts the following technical solution: Methods to prevent interception during PCB manufacturing processes include: In the PCB forming process, the information of the first piece of board after processing is recorded, and the first piece and sampling inspection production report of the process is generated. The first piece and sampling inspection production report of the process are checked against the standard data table preset in the server. After the check is correct, proceed to the next step. The processed first piece is sent to IPQC for re-inspection and confirmation, and the re-inspection information is recorded. An IPQC first piece inspection report is generated, and then the IPQC first piece inspection report is linked with the process first piece and sampling production report. Check if the first piece inspection and sampling production reports for each process are filled out completely; if not, issue an alarm to prompt the operator to supplement the report information; if the reports are filled out completely, proceed to the next step. Once the first piece inspection report, sampling production report, and IPQC first piece inspection report for each process are all recorded completely and verified to be correct, the PCB board will be transferred to the next process.

[0011] The present invention also provides a device for preventing interception during the PCB forming process, comprising: The record generation unit is used to record the information of the first piece of PCB after processing in the PCB forming process, and to generate the first piece and sampling inspection production report of the process. The verification unit is used to verify the first piece and sampling production report of the process with the standard data table preset in the server. After the verification is correct, the process proceeds to the next step. The re-inspection association unit is used to send the processed first piece board to IPQC for re-inspection and confirmation, record the re-inspection information, generate the IPQC first piece inspection report, and then associate the IPQC first piece inspection report with the process first piece and sampling production report. The inspection unit is used to check whether the first piece and sampling production reports of the process are filled out completely; if they are not filled out completely, an alarm will be issued to prompt the operator to supplement the report information; if they are filled out completely, proceed to the next step. The posting unit is used to post the PCB board to the next process after the first piece of the process, the sampling production report, and the IPQC first piece inspection report are all recorded completely and verified to be correct.

[0012] The present invention also provides a computer device, the computer device including a memory and a processor, the memory storing a computer program, and the processor executing the computer program to implement the above-described method.

[0013] The present invention also provides a storage medium storing a computer program that, when executed by a processor, implements the above-described method.

[0014] The advantages of this invention compared to existing technologies are as follows: By recording the information of the first piece of board after processing in the PCB forming process and generating process first piece and sampling inspection production reports, combined with IPQC re-inspection confirmation and report association mechanisms, it ensures that each processing step has a clear record and review process. This dual verification mechanism fundamentally eliminates the occurrence of missed processes, avoids product quality problems caused by missed processing, and significantly improves the product pass rate. In addition, it allows arbitrary sorting of processing between sub-processes within the forming process (such as large board Vcut, finished product Vcut, etc.) without the problem of missed processes. By verifying the process first piece and sampling inspection production reports with a standard data table preset in the server and ensuring that all relevant report records are complete, it achieves the processing of complex processes. The flexible management of processes improves production flexibility and efficiency while ensuring processing quality. Furthermore, during report completion, data verification and alarm mechanisms monitor the completeness and accuracy of reports in real time. If an incomplete report or incorrect data is detected, the system immediately issues an alarm to prompt operators to supplement or correct the information. This real-time monitoring mechanism not only avoids omissions and errors in recording but also improves the transparency and controllability of the production process. In addition, electronic reports and data association reduce reliance on traditional MES systems and complex inspection equipment, lowering system development and maintenance costs. Simultaneously, by preventing omissions in processes and records, rework and customer complaints due to product quality issues are reduced, significantly lowering production costs.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0021] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram illustrating an application scenario of the PCB forming process interception prevention method provided in an embodiment of the present invention. Figure 2 This is a schematic flowchart illustrating the PCB forming process interception prevention method provided in this embodiment of the invention. The method is applied to a server that interacts with a terminal. Through report association and data verification mechanisms, it effectively solves problems such as missing processes and missing report records in existing technologies, significantly improving the reliability and production efficiency of the PCB forming process, reducing production costs, and enhancing quality management capabilities, thus demonstrating significant economic and social benefits.

[0022] Figure 2 This is a flowchart illustrating the PCB forming process interception prevention method provided in an embodiment of the present invention. Figure 2 As shown, the method includes the following steps S110 to S150.

[0023] S110. In the PCB forming process, record the information of the first piece of board after processing, and generate the first piece and sampling inspection production report of the process. Specifically, after each processing step in the PCB forming process is completed, operators need to record the processing information of the first piece board, including but not limited to processing parameters, dimensional measurement results, and appearance inspection results. This information will be entered into an electronic "First Piece and Sampling Inspection Production Report." This report can be generated and managed through the company's internal production management system (such as an ERP system) or dedicated production data recording software.

[0024] In other words, by recording the information on the first piece and generating reports, it is ensured that each processing step is clearly documented, providing fundamental data for subsequent process verification and quality control. This recording method avoids omissions and errors that may occur with traditional manual recording, improving the accuracy and completeness of the data.

[0025] In one embodiment, the step of recording the information of the first piece of PCB after processing and generating the first piece and sampling inspection production report in the PCB forming process includes: In the PCB forming process, the first piece of board after processing is scanned to obtain its basic information, including product model, processing quantity and processing date. Specifically, after the PCB forming process is completed, operators use barcode scanners or QR code scanners to scan the first piece of board. The scanner reads the barcode or QR code on the first piece of board to obtain basic information, including product model, quantity, and processing date. This information is usually pre-printed on labels during production and attached to the first piece of board. The scanner is connected to the production management system; after scanning, the basic information is automatically uploaded to the system, avoiding errors and omissions that may occur with manual input.

[0026] Collect dimensional measurement data of the first piece and record the tolerance range to form measurement information; Specifically, operators use high-precision measuring tools (such as calipers, micrometers, or automated measuring equipment) to measure the critical dimensions of the first piece sheet. The measuring tools transmit dimensional data to the production management system and record the tolerance range for each dimension. For example, if the standard value for a dimension is 10mm and the tolerance range is ±0.1mm, the measuring equipment will record the actual measured value and determine whether it is within the tolerance range. The measuring equipment can connect directly to the production management system via a data interface (such as USB, RS232, or a network interface) to achieve automatic data transmission and recording. The system automatically verifies whether the measured values ​​are within the preset tolerance range and issues an alarm when they exceed the range.

[0027] Input basic information and measurement information into the production management system to generate first-piece and sampling inspection production reports.

[0028] Specifically, the basic information obtained from scanning and the dimensional data collected by measuring equipment are input into the production management system. The system automatically generates first-piece and sampling inspection production reports based on preset templates and rules. The reports include information such as product model, processing quantity, processing date, dimensional measurement data, and tolerance range. The production management system integrates the basic and measurement information into the reports using scripts or automated tools and performs formatting. After the reports are generated, the system automatically saves them and provides them to relevant personnel for viewing and review.

[0029] In other words, by automatically acquiring the basic information of the first piece sheet through scanning equipment, errors and omissions that may occur with manual input are avoided. Simultaneously, the automatic data transmission function of the measuring equipment ensures the accuracy and real-time nature of dimensional measurement data. This automated data acquisition method significantly improves the efficiency and accuracy of data collection, reducing production problems caused by data errors. Furthermore, when acquiring dimensional measurement data, the system automatically records the tolerance range and issues an alarm when the measured value exceeds the tolerance range. This real-time quality monitoring mechanism can promptly detect quality problems during processing, ensuring that the quality of each first piece sheet meets requirements. In this way, rework and customer complaints caused by quality problems can be effectively avoided, improving the product pass rate.

[0030] S120. Check the first piece and sampling production report of the process against the standard data table preset in the server. If the check is correct, proceed to the next step. Specifically, the generated first-piece and sampling inspection production reports are compared with a standard data table preset on the server. The standard data table contains the correct parameters and quality standards for all processing steps. The verification process can be completed by an automated script program, which checks whether the data in the reports conforms to the preset standard range. For example, whether the dimensional measurement results are within tolerance range, and whether the processing parameters meet the process requirements, etc.

[0031] In other words, by comparing the data with standard data sheets, potential deviations and errors during processing can be detected in a timely manner, ensuring that the quality of each processing step meets requirements. This automated verification mechanism improves verification efficiency, reduces oversights that may occur during manual verification, and thus effectively improves the reliability of the production process and product quality.

[0032] In one embodiment, the step of comparing the first piece and sampling inspection production report with a standard data table preset in the server, and proceeding to the next step after confirming that there are no errors, includes: Retrieve the preset standard data table from the server; Specifically, in the production management system, a standard data table is preset in advance. This table stores the correct parameters and quality standards for each processing link in the PCB forming process. These standard data include dimensional tolerance ranges, processing parameters, appearance requirements, etc. When verification is required, the system retrieves these preset standard data tables from the server for subsequent comparison. The standard data table is usually stored in the server in the form of a database and is called through the background program of the production management system. The retrieval process can be achieved through SQL query statements or other database access technologies to ensure the accuracy and timeliness of the standard data.

[0033] Compare the data information in the first-piece inspection report and sampling inspection production report of the process item by item with the standard data table. Specifically, the system automatically compares each item of data in the first-piece inspection report and sampling inspection production report of the process with the corresponding data in the standard data table item by item. The comparison process includes but is not limited to whether the dimensional measurement values are within the tolerance range, whether the processing parameters meet the requirements, whether the appearance inspection results are qualified, etc. The comparison logic can be implemented through a preset script program or algorithm. Among them, the comparison process can be completed through an automated script or plug-in. The script will read the data in the production report item by item and compare it with the data in the standard data table. For example, for dimensional measurement values, the script will check whether the actual measurement values are within the standard tolerance range (such as ±0.1mm). If the data is consistent or within the allowable range, it will be marked as "verified correctly"; if it exceeds the range, it will be marked as "data anomaly".

[0034] If data anomalies occur, the system records the anomaly information and issues an alarm; if the verification is correct, proceed to the next step.

[0035] Specifically, if data anomalies are found during the comparison process, the system will automatically record the anomaly information, including the specific content of the abnormal data, the type of anomaly (such as exceeding the tolerance range, data missing, etc.), and the process link where the anomaly occurs. At the same time, the system will trigger an alarm mechanism to notify the operator or manager to handle it. The alarm can be achieved through various methods, such as pop-up prompts, sound alarms, SMS notifications, or email reminders. The anomaly information will be stored in the system log file or database for subsequent query and analysis. The alarm mechanism can be implemented through the built-in reminder function of the system. For example, when an anomaly is detected, the system will automatically send an alarm message to the specified terminal device or the email of the relevant person.

[0036] In other words, by using automated scripts and algorithms to compare data item by item, the system avoids omissions and errors that may occur during manual verification. The system can quickly and accurately complete the verification of large amounts of data, significantly improving the efficiency and accuracy of data verification. This automated verification mechanism not only saves time but also reduces errors caused by human factors. Furthermore, during the verification process, if any data anomalies are detected, the system immediately records the anomaly information and issues an alarm, notifying relevant personnel to handle the issue promptly. This real-time monitoring mechanism can quickly identify quality problems in the production process, preventing further escalation and thus reducing rework and waste caused by quality issues, thereby improving the product qualification rate.

[0037] S130. Send the processed first piece to IPQC for re-inspection and confirmation, record the re-inspection information, generate the IPQC first piece inspection report, and then link the IPQC first piece inspection report with the process first piece and sampling production report. Specifically, the first piece of workpiece after processing needs to be sent to IPQC (In-Process Quality Control) for re-inspection and confirmation. IPQC personnel record the re-inspection information in the "IPQC First Piece Inspection Report," which is also generated and managed through an electronic system. Subsequently, the system links the IPQC First Piece Inspection Report with the process first piece and sampling inspection production reports to ensure data consistency and completeness between the two reports.

[0038] In other words, IPQC's re-inspection provides additional quality assurance for the production process, further ensuring the quality of the first piece through independent third-party inspection. The report correlation mechanism ensures the integrity and consistency of production data, avoiding production errors and quality problems caused by inconsistent report data, and enhancing the transparency and controllability of the production process.

[0039] In one embodiment, the step of sending the processed first piece to IPQC for re-inspection and confirmation, recording the re-inspection information, generating an IPQC first piece inspection report, and then associating the IPQC first piece inspection report with the process first piece and sampling inspection production reports includes: The first piece of the processed board is sent to the IPQC inspection area; Specifically, after the PCB forming process is completed, operators transfer the processed first piece of board from the production area to the IPQC (In-Process Quality Control) inspection area. This process can be completed manually or with automated transfer equipment, ensuring the first piece of board arrives at the inspection area safely and accurately. The inspection area is typically equipped with specialized inspection equipment and workbenches to support detailed re-inspection operations by IPQC personnel. The first piece of board should be accompanied by necessary identification information (such as barcodes or QR codes) during the transfer process to facilitate quick identification and recording by IPQC personnel.

[0040] Perform a re-inspection on the first piece and record the re-inspection information; Specifically, IPQC personnel perform re-inspection of the first piece in the inspection area. Re-inspection includes, but is not limited to, dimensional measurements, visual inspection, and functional testing; specific inspection items are determined based on product standards and process requirements. IPQC personnel use high-precision measuring tools (such as calipers, micrometers, and optical measuring equipment) and visual inspection equipment (such as microscopes and AOI equipment) to conduct the inspection and record the re-inspection results. Re-inspection information includes dimensional measurements, descriptions of visual defects, and functional test results. This information is either manually entered by IPQC personnel or automatically transmitted to the production management system. The system automatically verifies whether the re-inspection data conforms to preset standard ranges and issues an alarm when an anomaly is detected.

[0041] Input the re-inspection information into the production management system to generate the IPQC first piece inspection report; Specifically, IPQC personnel input the re-inspection information into the production management system. The system automatically generates an IPQC first-piece inspection report based on preset templates and rules. The report includes detailed information such as the product model of the first piece, processing date, re-inspection items, re-inspection results, and whether it meets standards. The production management system receives the re-inspection information through a data interface and formats it. After the report is generated, the system automatically saves it and provides it to relevant personnel for viewing and review. The report format and content can be customized according to the specific needs of the company to ensure the completeness and readability of the information.

[0042] Link the IPQC first piece inspection report with the process first piece and sampling inspection production reports.

[0043] Specifically, the system automatically links the generated IPQC first-piece inspection report with the process first-piece and sampling inspection production reports. This linking process is achieved through data matching, for example, matching based on key information such as product model, processing date, or batch number. After linking, the data from the two reports are integrated to form a complete quality record. The linking mechanism can be implemented through database queries and scripts. The system checks whether key fields in the two reports are consistent to ensure data accuracy and completeness. After linking, the system generates a comprehensive quality record, facilitating subsequent quality analysis and traceability.

[0044] In other words, IPQC's re-inspection and confirmation provide additional quality assurance for the production process. IPQC's independent inspection can promptly identify potential missed or incorrect inspections during production, ensuring that each first piece meets quality requirements. This dual inspection mechanism significantly improves the reliability and effectiveness of quality control. Furthermore, the detailed re-inspection information recorded by IPQC personnel during the inspection process is used by the production management system to generate standardized inspection reports, ensuring the completeness and accuracy of data records. This automated recording method avoids errors and omissions that may occur with manual recording, improving data reliability.

[0045] S140. Check whether the first piece and sampling production reports for the process are filled out completely; if not, issue an alarm to prompt the operator to supplement the report information; if filled out completely, proceed to the next step. Specifically, the system automatically checks whether the first-piece and sampling production reports for each process are complete. The check includes verifying for missing items and ensuring the data conforms to logical and formatting requirements. If an incomplete or erroneous report is found, the system will automatically issue an alert, reminding operators to supplement or correct the information. Alerts can be issued in various ways, such as pop-up notifications, sound alerts, or SMS notifications.

[0046] In other words, automated inspection and alert mechanisms ensure the completeness and accuracy of report data. This mechanism effectively avoids production interruptions and quality problems caused by incomplete or incorrect report entries, improving the efficiency and reliability of the production process and reducing the risks associated with human error.

[0047] In one embodiment, the inspection process checks whether the first piece and sampling production report are completely filled out; if not, an alarm is issued to prompt the operator to supplement the report information; if complete, the process proceeds to the next step, including: Check whether each item in the first piece inspection and sampling production report is filled out completely; Specifically, within the production management system, an automated inspection program is set up to check the completeness of data in the first-piece and randomized production reports for each process step. The system verifies that each item in the report is filled in according to preset rules and field lists. The inspection program can be implemented through database queries and scripts; the system reads each data item in the report and checks for empty or missing values. For example, it checks whether fields such as dimensional measurements, processing parameters, and inspection results are filled in.

[0048] If there are blank or missing items in the report, an alarm will be issued to prompt the operator to fill in the missing information; Specifically, if the inspection process finds blank or incomplete entries in the report, the system will automatically trigger an alarm mechanism to notify the operator to fill in the missing information. Alarms can be triggered in various ways, such as pop-up notifications, sound alerts, SMS notifications, or email reminders. The alarm message will include specific information about the missing field, such as "Dimensional measurement value not filled" or "Inspection result empty." The system will record detailed information about these missing fields for subsequent querying and processing.

[0049] After the operator supplements the missing information according to the system prompts, the system re-verifies the integrity. Specifically, operators supplement the missing report information according to system prompts. After supplementation, operators re-enter the updated information into the production management system. The system automatically performs an integrity check again to ensure that all missing information has been supplemented. The system will then run the check program again to verify that each item in the report is complete. If any items are still missing, the system will continue to issue alerts until all information is complete.

[0050] If the report is completed, proceed to the next step.

[0051] Specifically, if the inspection process confirms that every item in the report has been completed completely, the system will automatically mark the report as "completeness check passed" and allow the process to proceed to the next step. This step could be transferring the report data to the next process step or conducting subsequent quality audits. The system will record the report's completeness check result and save the complete report data to the database for later querying and traceability. Simultaneously, the system will trigger the next step in the process flow to ensure the continuity of production.

[0052] In other words, through automated integrity checks and alert mechanisms, the system ensures that every piece of data in the first-piece and sampling inspection production reports is complete. This mechanism avoids production errors and quality problems caused by incomplete report data, improving data accuracy and reliability. Furthermore, the automated checking and alert mechanisms reduce the time and errors of manual checks, increasing the efficiency of report completion. Simultaneously, by promptly identifying and supplementing missing information, the system ensures the smooth operation of the production process, preventing production interruptions due to incomplete data, thereby improving production efficiency and quality control capabilities.

[0053] S150. Once the first piece inspection report, sampling production report, and IPQC first piece inspection report for each process are all recorded completely and verified to be correct, the PCB board will be transferred to the next process.

[0054] Specifically, once the first piece inspection report, sampling production report, and IPQC first piece inspection report for each process are complete and verified to be accurate, the system will post the PCB board information to the next process. This posting process can be automated through an ERP system or other production management systems, ensuring the continuity of the production process and real-time data updates.

[0055] In other words, rigorous report verification and completeness checks ensure that only PCBs that fully meet the requirements can proceed to the next process. This mechanism effectively eliminates omissions in processes and records, guaranteeing the continuity of production and the stability of product quality. Simultaneously, the automated posting mechanism improves production efficiency and reduces manual operation time and errors.

[0056] In one embodiment, when the first-piece production report of the process and the IPQC first-piece inspection report are both recorded completely and verified without errors, posting the PCB board to the next process includes: Recheck the integrity and accuracy of the first-piece production report of the process and the sampling inspection production report against the IPQC first-piece inspection report; Specifically, in the production management system, an automated verification program is set up to recheck the integrity and accuracy of the first-piece production report of the process and the sampling inspection production report against the IPQC first-piece inspection report. The verification content includes checking whether the reports are filled out completely, whether the data is accurate, and whether it meets the preset standard range, etc. The verification program is implemented through database queries and scripts. The system reads each piece of data in the two reports and verifies one by one whether it is filled out completely and the data is accurate. For example, check whether the dimension measurement value is within the tolerance range and whether the inspection result is qualified, etc. The detailed comparison results will be recorded during the verification process for subsequent processing.

[0057] If the verification is correct, update the status of the PCB board to "posted", and record the posting time, posting status, and operator information; Specifically, if the verification program confirms that both reports are complete and accurate, the system will automatically update the status of the PCB board to "posted". At the same time, the system will record the posting time, posting status (such as "success" or "failure"), and operator information (such as operator name, employee number, etc.). The system updates the status field of the PCB board through database operations and records the posting time, status, and operator information in the log file. These information will be permanently saved for subsequent traceability and auditing. For example, the system will update the status field of the PCB board in the database from "pending posting" to "posted", and record the current timestamp and the employee number of the operator.

[0058] Push the information of the PCB board to the production management system of the next process and allow it to enter the next process; Specifically, the system pushes the information of the posted PCB board to the production management system of the next process. The pushed information includes the basic information of the PCB board (such as product model, batch number, etc.), processing status, posting time, etc. After receiving the information, the production management system of the next process automatically sets the status of the PCB board to "pending processing" and allows it to enter the next process. Among them, the information push can be achieved through an interface between systems (such as API). The system encapsulates the detailed information of the PCB board into a data packet and transmits it through the network to the production management system of the next process. After receiving the data packet, the system of the next process automatically updates the status of the PCB board in the database and generates corresponding task instructions to notify the operator to start processing the next process.

[0059] If abnormalities are found during the verification, issue an alarm to prompt the operator to check and correct the problem until the verification is correct.

[0060] Specifically, if the verification process detects anomalies in the report (such as missing data or data errors), the system will automatically issue an alert, notifying the operator to check and correct the problem. Alerts can be sent via pop-up notifications, sound alerts, SMS notifications, or email reminders. The alert message will include the specific content and location of the anomaly, such as "Dimensional measurement values ​​exceed tolerance range; please check and correct." After the operator corrects the problem according to the alert prompts, the system will re-verify until the report is complete and accurate. The correction process will be recorded by the system for subsequent querying and analysis.

[0061] In other words, by double-checking the completeness and accuracy of the reports, all data for the PCB board before posting is ensured to be accurate. This double-checking mechanism avoids production problems caused by data errors, ensuring the accuracy and continuity of the production process. Only after all data has been verified is the PCB board allowed to proceed to the next process, thereby reducing the risk of production interruptions. Furthermore, the system automatically records posting time, status, and operator information, providing production managers with detailed production data and operation records. This transparent management approach helps to better monitor production progress and promptly identify and resolve problems. Simultaneously, the automated posting mechanism reduces manual operation time and errors, improving the efficiency of production management. Moreover, by recording detailed posting and operator information, the system provides strong support for quality control and traceability in the production process. Managers can use these records to quickly pinpoint the root cause of problems and take targeted improvement measures. This data-driven quality management approach helps companies continuously improve product quality and enhance market competitiveness.

[0062] The aforementioned PCB forming process interception prevention method records the information of the first piece of board after processing during the PCB forming process and generates process first piece and sampling inspection production reports. Combined with IPQC re-inspection confirmation and report association mechanisms, it ensures that each processing step has a clear record and review process. This dual verification mechanism fundamentally eliminates the occurrence of missed processes, avoids product quality problems caused by missed processing, and significantly improves the product pass rate. In addition, it allows arbitrary sorting of sub-processes within the forming process (such as large board Vcut, finished product Vcut, etc.) without the problem of missed processes. By verifying the process first piece and sampling inspection production reports with a standard data table preset in the server and ensuring that all relevant report records are complete, it achieves control over complex processes. The flexible management of processes improves production flexibility and efficiency while ensuring processing quality. Furthermore, during report completion, data verification and alarm mechanisms monitor the completeness and accuracy of reports in real time. If an incomplete report or incorrect data is detected, the system immediately issues an alarm to prompt operators to supplement or correct the information. This real-time monitoring mechanism not only avoids omissions and errors in recording but also improves the transparency and controllability of the production process. In addition, electronic reports and data association reduce reliance on traditional MES systems and complex inspection equipment, lowering system development and maintenance costs. Simultaneously, by preventing omissions in processes and records, rework and customer complaints due to product quality issues are reduced, significantly lowering production costs.
