Detailed Description

The application is described in further detail below with reference to fig. 1-8.

The embodiment of the application discloses an information tracing method, as shown in fig. 1, comprising the following steps:

S101, acquiring an information tracing request;

s102, analyzing the information tracing request to generate an information tracing item corresponding to the target product;

s103, identifying information tracing items and obtaining corresponding information state identifiers;

s104, if the information state identification is normal, processing information of the target product is obtained, wherein the processing information comprises a process flow node of the target product and verification authority data corresponding to the process flow node;

s105, acquiring processing record parameters and processing calibration parameters corresponding to the process flow nodes;

s106, if the parameter error between the machining record parameter and the machining calibration parameter exceeds a preset parameter error threshold, acquiring corresponding verification personnel and authority dividing records in the verification authority data as identification anomaly traceability results;

s107, if the information state is marked as abnormal, acquiring an abnormal circulation node of the target product;

s108, if the abnormal flow node approaches a plurality of process flow nodes, acquiring abnormal feedback configuration information and processing verification operation records corresponding to each process flow node as information abnormal traceability feedback results.

In step S101, the information tracing request refers to an operation of obtaining detailed record information of all information, parameters, states, etc. corresponding to a certain production process or product by using the process or product as a starting point and through system query and analysis.

Specifically, the detailed records include material production lot of the product, processing state, process parameters, records of personnel operations, quality inspection data, and the like. The viewing and tracing can be performed according to a time axis or a flow node.

In step S102, data analysis and processing are performed in the MES system, mainly according to the query request issued by the current user, so as to quickly lock and acquire product information in the process of machining and production. The information tracing item refers to detailed record information corresponding to a certain processing and production process or product generated according to the user query requirement in the MES system. The information trace items can specifically comprise information items such as production batch, processing state, process parameters, personnel operation records and the like of the product.

In step S103, in the MES system, the information trace-back item may be checked and traced according to the time axis or the flow node, and in order to better express the state of the information trace-back item, a state identifier is set for each information trace-back item, where the state identifier reflects the state of the information trace-back item, so as to facilitate the query analysis and processing of the user.

For example, for the material information of a product, the status identification includes: warehousing, waiting to be detected, disqualification and the like, and for the process parameter information, the state identification comprises: standard flow, abnormal flow, to be audited, etc.

In step S104, if the information status identifier is normal, it is indicated that the information tracing item is in a normal status, that is, the information tracing item meets the auditing standard specification corresponding to the MES system, in order to reduce the possible problems of private tampering and covering of abnormal target product information in the processing information of the target product, the processing information corresponding to the information tracing item is further obtained, the processing information includes a process flow node of the target product and verification authority data corresponding to the process flow node, the process flow node refers to a processing process flow node along which the target product is processed and manufactured corresponding to the specific information tracing item, and the verification authority data refers to quality monitoring operation authority data corresponding to each process flow node. The information state identification is normal, and the identification can be performed by setting a green induction lamp or popping up prompt information of the type of information tracing item in a normal state.

For example, in the manufacturing process of the Flexible Printed Circuit (FPC), the information tracing item is copper plating, the corresponding information state identification is displayed as normal, namely, each processing parameter of the circuit board during copper plating is indicated to be in accordance with the quality parameter detection specification of the node, and the processing information corresponding to the copper plating node of the circuit board is further obtained, wherein the process flow node comprises the pickling time, the cleaning times, the current density, the copper plating time, the copper salt concentration and the PH value of the circuit board, and the verification authority data is the identity and the detailed parameter verification record data of the quality monitoring operation authority personnel corresponding to each process flow node.

In practical application, in the process of processing and producing a target product, corresponding operators privately tamper with product processing parameters or mask actual detection information of abnormal target products, which may cause the MES system to identify that the unqualified product is displayed as a qualified product, and then the unqualified product is judged as a qualified product, thereby influencing the product quality.

For example, in the manufacturing process of the FPC flexible circuit board, in the processing and manufacturing node of chemical etching, the etching operation of the node does not reach the standard, and corresponding operators falsify etching processing data privately and mask real information of the circuit board in the processing and manufacturing node of chemical etching, so that the MES system can misjudge the etching quality of the batch of circuit boards, and further influence the subsequent processing quality of the circuit boards.

In step S105, processing record parameters and processing calibration parameters corresponding to the process flow nodes are obtained. The processing record parameters are processing parameters automatically recorded by the target product in the MES system of the corresponding process flow node, and the processing calibration parameters refer to the processing parameters verified and uploaded by the corresponding operator of the process flow node.

For example, in a copper-plated node of an FPC flexible circuit board, the standard pickling time is 5 to 10 seconds, the allowable time error between the upper and lower sides is +/-0.5 seconds, and because of the compliance error, the system easily misjudges the processing parameters meeting the standard as non-compliance, so that related operators are required to verify the processing parameters and upload and calibrate the final pickling time parameters, the system again carries out identification analysis on the uploaded pickling time parameters, and if the pickling time standard is met, the copper-plated node is normal.

The operator is given a certain right to modify the processing parameters, so that the parameters of the target product in the processing and manufacturing process may be tampered privately by the operator, and the output of a large number of non-compliant products may be increased. Therefore, the information state identification is displayed as a normal information trace item, and further the processing data of the process flow nodes are deeply analyzed, namely the processing record parameters and the processing calibration parameters of the process flow nodes are analyzed, so that the abnormal misjudgment problem of the unqualified products can be effectively traced.

In step S106, if the parameter error between the machining record parameter and the machining calibration parameter exceeds the preset parameter error threshold, it is indicated that the machining parameter of the target product is suspected of being tampered privately, and the corresponding verification personnel and permission division record in the verification permission data corresponding to the process flow node are further obtained as the identification anomaly tracing feedback result. The preset parameter error threshold value is an error numerical range allowed to exist between the pointer pair processing record parameter and the processing calibration parameter.

For example, at a copper plating processing node of an FPC flexible circuit board, the standard pickling time is 5 to 10 seconds, the preset parameter error threshold value is that the standard pickling time error is +/-0.5 seconds, the corresponding processing record parameter, namely the pickling time, is 10.7 seconds, but the processing calibration parameter uploaded and calibrated by the pickling time is displayed for 10.5 seconds, and the parameter error between the processing record parameter and the processing calibration parameter of the copper plating pickling time can be judged to exceed the corresponding preset parameter error threshold value.

Further, the identity information of the verification personnel corresponding to the copper plating and acid washing time and the authority division record are obtained, wherein the authority division record displays the verification authority distribution information of each process flow node in the copper plating link. For example, copper plating includes process flow nodes of acid washing, cleaning, electrolytic copper plating and gold plating, each of the process flow nodes has a verification personnel matched with the process flow nodes, and the verification authority data includes division information of the verification authorities of the verification personnel on the processing parameters in the copper plating link. And furthermore, abnormal problems and personnel can be traced and identified timely and accurately through the verification personnel and the authority division record.

In step S107 to step S108, if the information status is identified as abnormal, it is indicated that erroneous judgment on the abnormal product may occur due to abnormal data deletion occurring in the system, in order to effectively trace the abnormality occurring in the system, the abnormal circulation node of the corresponding target product is obtained, and if the abnormal circulation node has passed through a plurality of process flow nodes, it is indicated that abnormal feedback configuration information of the MES system or abnormal processing verification operation occurs in an individual process flow node, so that the above-mentioned two information is obtained and used as an information abnormality tracing feedback result.

Specifically, the abnormal feedback configuration information of the MES system refers to that in the processing and production process, if abnormal conditions occur, the abnormal feedback configuration information is obtained to stop production in time and feed back the abnormal conditions to related management staff. For example, in the manufacturing process of FPC flexible circuit board, if the copper plating parameters of a certain batch of circuit boards are out of the preset range, the MES system automatically gives an alarm and stops the copper plating operation until the abnormality is eliminated. If the abnormal flow node passes through a plurality of process flow nodes at this time, the system is explained that the problem that the data operation error causes the error of the abnormal feedback configuration information possibly occurs.

In the manufacturing process of the FPC flexible circuit board, the situations that the FPC flexible circuit board does not meet the processing specification include: inaccurate cutting of the plate, if the plate is not cut according to the manufacturing specification, the plate is inaccurate in size, and therefore subsequent processing and assembly are affected; the welding temperature is controlled improperly, the welding of the FPC flexible circuit board needs to master proper temperature and time, otherwise, the problems of infirm welding, lead fracture and the like are easy to occur; the printing quality does not reach the standard, a high-quality printer and ink are required to be used when the flexible circuit board is printed, otherwise, the printing quality is affected, and even the board is damaged; poor sheet metal forming, if the sheet metal forming is improper, the problems of deformation or edge cracking of the plate and the like can be caused.

And secondly, the obtained processing verification operation records can further display the specific change condition of the abnormal feedback configuration and various operation records of the target product when the target product passes through a plurality of process flow nodes, wherein each step of abnormal feedback execution action is included, and the target product passes through the specific execution information corresponding to the abnormal circulation node.

The information tracing method provided by the embodiment analyzes the current information tracing request, can generate various information tracing items contained in the corresponding target product, further identifies the information tracing items, can acquire information state identifiers indicating actual states of the various information tracing items, if the information state identifiers are normal, indicates that production information corresponding to the current information tracing items accords with product production requirements, in order to further verify the information tracing items displayed normally so as to reduce the occurrence of distortion conditions of information tracing results caused by actions such as information tampering and data deletion, acquires processing information of the target product, namely process flow nodes for processing the target product and verification authority data passing through the process flow nodes, if parameter errors between processing record parameters corresponding to the process flow nodes and processing calibration parameters exceed preset parameter error thresholds, indicates that the processing information of the current target product possibly has private tampering and covers the problem of abnormal target product information, further acquires personnel and authority division records in authority data corresponding to the process flow nodes as identification abnormal tracing feedback results, can timely carry out accurate verification on personnel identities and operation authority identifiers of the process nodes through the identification abnormal tracing results, if the processing information corresponding to the process flow nodes are abnormal, and if the abnormal process flow nodes are not configured as the abnormal process flow nodes, and if the abnormal process flow data corresponding to the abnormal flow nodes are not configured and the abnormal process flow data are not configured, the abnormal flow nodes are configured and the abnormal process flow data is not configured, and the abnormal process flow nodes are not configured and the abnormal process flow nodes are required to be checked, the abnormal and the abnormal process flow nodes are required is required to be processed, the abnormal process flow nodes can be accurately positioned and the corresponding abnormal feedback configuration information and information verification operation are deeply analyzed through the abnormal tracing feedback result, and the tracing effect of the target product information is improved due to the fact that the information tracing item displaying the normal information state identification is approved again and the abnormal feedback operation analysis is conducted on the information tracing item displaying the abnormal information state identification.

In one implementation manner of this embodiment, as shown in fig. 2, after step S105, the process record parameters and the process calibration parameters corresponding to the process flow nodes are obtained, the method further includes the following steps:

s201, if the processing calibration parameters meet the numerical calibration standards of the processing record parameters of the process flow node calibration, judging whether a parameter selection interval corresponding to the processing calibration parameters meets interval selection standards or not;

s202, if a parameter selection interval corresponding to the processing calibration parameters does not meet an interval selection standard, calibrating the process flow node to be an abnormal process flow node, and acquiring a circulation state of an abnormal target product corresponding to the abnormal process flow node;

s203, if the circulation state is in a factory, acquiring a current circulation node of an abnormal target product as abnormal detection feedback;

s204, if the circulation state is factory leaving, acquiring the production batch of the abnormal target product and the butt-joint client as abnormal detection feedback.

In step S201 to step S202, in the manufacturing process of the FPC flexible circuit board, each processing flow node has a corresponding calibration parameter and a record parameter, and on the basis that the processing calibration parameter meets the numerical calibration specification of the processing flow node calibration processing record parameter, the parameter selection interval corresponding to the processing calibration parameter needs to be detected to ensure that the parameter selection interval meets the selection standard of the parameter interval, if the parameter selection interval corresponding to the processing calibration parameter does not meet the interval selection standard, the processing flow node is determined to be an abnormal processing flow node.

For example, in the copper plating step of the flexible printed circuit board (FPC), the FPC is required to be soaked under the conditions that the copper salt concentration is 150g/L, the temperature is 30 ℃, the PH value is 3.8 and the soaking time is 40 minutes, namely, the interval selection standard is carried out, and even if the processing calibration parameters meet the numerical calibration standards of the copper plating calibration processing record parameters, the condition that the parameter selection interval does not meet the corresponding interval selection standard can also cause the copper plating non-standard condition of the circuit board due to the omission parameter item in the copper plating process of the circuit board.

For another example, the interval selection standard corresponding to the copper plating link is that the copper salt concentration is 150g/L, the temperature is 30 ℃, the PH value is 3.8, and the soaking time is 40 minutes, then the parameter selection interval corresponding to the current processing calibration parameter is that the copper salt concentration is 150g/L, and the temperature is 30 ℃, and then it can be determined that the parameter selection interval corresponding to the processing calibration parameter of copper plating does not meet the interval selection standard corresponding to the processing calibration parameter of copper plating.

In step S203 to step S204, in order to accurately trace the abnormal target product in time, the current circulation state of the abnormal target product may be obtained through the MES system.

For example, in the manufacturing process of the FPC flexible circuit board, the corresponding abnormal process flow node and the abnormal target product are found through the analysis, at the moment, the MES system can automatically detect the circulation states of all the target products related to the abnormal process flow node, and corresponding abnormal detection feedback is generated according to the actual situation.

If the abnormal target product is still in the factory, the MES system can acquire the current circulation node of the product as abnormal detection feedback. For example, assume that a target product (e.g., a mobile phone motherboard) is undergoing a multi-layer printing process, but a specific node is abnormal, so that the product needs to be reprocessed. At this point the MES system will detect the circulation status of the product, find that it is still in the production plant, and record the current circulation node for subsequent processing and follow-up.

Secondly, if the target product is shipped, the MES system can acquire information such as the production batch of the product and the butt-joint clients as abnormality detection feedback. For example, assume that a certain target product (e.g., an LED light bar) has completed the entire production process and has been assembled for delivery to a customer. However, if the analysis is performed to obtain that part of target products have abnormal parameter selection detection problems, the MES system detects the circulation state of the products, finds that the products are delivered, records the production batches and the butt-joint clients, and facilitates subsequent after-sales service and business management.

The information tracing method provided by the embodiment can monitor and feed back the parameter acquisition and detection of the target product in real time in the processing and production process, reduces the occurrence of omission of unqualified products and difficult tracing of unqualified products due to the fact that the parameter acquisition and detection mode of the target product is out of specification, and accordingly improves the tracing effect of the information of the target product.

In one implementation manner of the present embodiment, as shown in fig. 3, in step S203, if the circulation state is in the factory, the method further includes the following steps after obtaining the current circulation node of the abnormal target product as the abnormality detection feedback:

s301, if parameter abnormal association exists in the current circulation node, acquiring an abnormal association result corresponding to the parameter abnormal association;

s302, forming an abnormality investigation item corresponding to the abnormal target product according to the abnormality association result.

In step S301, the abnormal parameter association refers to an association relationship that the processing operation of the current flow node where the abnormal target product is located causes the abnormality of other process flow nodes, and if the abnormal parameter association exists in the current flow node, it is indicated that the current flow node generates the processing operation that causes the abnormality of other process flow nodes, and the abnormal association result refers to the actual content that the current flow node causes the specific abnormality of other process flow nodes. Whether the current circulation node has abnormal association of parameters can be judged through detecting the processing parameters of the current circulation node.

For example, in the process of drilling holes in an FPC flexible circuit board, drilling holes is one of the important processes for manufacturing the FPC flexible circuit board, and if the drilling holes are inaccurate in position or inconsistent in pore size, subsequent copper plating and finished product testing can be affected. The obtained drilling position and the hole diameter are related to abnormal parameters of the drilling process flow node, and the corresponding abnormal related results are the influence on the subsequent copper plating and finished product testing.

Specifically, the abnormal association results include that the inaccurate drilling position can cause the copper foil to be not covered in place, so that the subsequent copper plating process is affected, if the copper foil is not covered enough, a local current path can be caused, and even a circuit is invalid when the copper foil is seriously covered; secondly, the inconsistent size of the bore hole also has an influence on copper plating and finished product testing, if the bore hole is too large, the bonding pad is not easy to adhere, and if the bore hole is too small, the bonding pad is easy to turn up, and the welding reliability can be influenced.

In step S302, according to the result of the abnormality association, an abnormality investigation item corresponding to the abnormality target product is formed, and according to the abnormality investigation item, the abnormality product can be subjected to abnormality location investigation in advance, thereby improving the abnormality processing efficiency of the abnormality target product. For example, the current flow node is a drill hole, the parameter anomaly association is the size of the drill hole, the result of the anomaly association is line failure and pad anomaly, and the corresponding anomaly investigation item is line and pad detection.

It should be noted that, no matter whether the processing of the abnormal target product is finished or not by the current circulation node, as long as the system detects that the parameter abnormal association exists in the current circulation node, an abnormal investigation item for inspecting the abnormal target product can be formed according to the corresponding abnormal association result, so as to promote the comprehensiveness of the abnormal tracing of the abnormal target product.

According to the information tracing method provided by the embodiment, the quality problems possibly occurring in the abnormal target product can be timely and accurately confirmed and inspected according to the abnormal inspection item, so that the comprehensiveness of the abnormal tracing and inspecting of the abnormal target product is improved.

In one implementation manner of this embodiment, as shown in fig. 4, after step S302, that is, according to the result of the abnormality association, the abnormality examination item corresponding to the abnormality target product is formed, the method further includes the following steps:

s401, if a plurality of abnormal association results are obtained, obtaining abnormal hazard grades corresponding to the abnormal association results;

s402, setting the investigation priority of the abnormal investigation item corresponding to the abnormal target product according to the abnormal hazard level;

s403, carrying out abnormal investigation on the abnormal target product according to the investigation priority.

In step S401, if the number of abnormality related results is plural, it is indicated that a plurality of abnormality hidden dangers are generated by the processing operation of the current circulation node, and in order to trace the hidden dangers further, the abnormality hazard levels corresponding to the abnormality related results are obtained, and the abnormality hazard levels are determined according to the specific hazard levels of the abnormality related results in the production and manufacturing process, and can be defined according to industry standards.

For example, the abnormal association results are association results caused by abnormal drilling processing of the circuit board, and specifically include weak welding, interface position deviation and finished product test failure. If the drilling positions are inaccurate or the pore sizes are inconsistent, the welding pads are deformed, so that the welding is unstable, the problems of breakage, short circuit and the like are easy to occur, and the corresponding abnormal hazard grades are general; if the drilling position is inaccurate, the position of the bonding pad of the FPC flexible circuit board is affected, so that the position of the interface and the position of the connector or the socket are deviated, line failure or data and signal transmission errors are easily caused, and the corresponding abnormal hazard level is serious; if the drilling position is inaccurate or the pore size is inconsistent, the normal running of the finished product test is affected, and the problems of short circuit, open circuit and the like of a circuit can be possibly caused, so that the quality and the reliability of the product are affected, and the corresponding hazard level is medium.

In step S402 to step S403, in order to improve the tracing efficiency of the abnormality association result, according to the determined abnormality hazard level, an troubleshooting priority of the abnormality objective product corresponding to the abnormality troubleshooting item is set, and the abnormality troubleshooting is performed on the abnormality objective product according to the set troubleshooting priority. The abnormal hazard level is in direct proportion to the investigation priority of the abnormal investigation item corresponding to the abnormal target product, namely, the higher the abnormal hazard level is, the higher the investigation priority corresponding to the abnormal hazard level is.

For example, according to the abnormal association results of the tracing, namely, welding infirm, interface position deviation and finished product test failure, the inspection priority corresponding to the interface position deviation is 1 level, the inspection priority corresponding to the finished product test failure is 2 level, and the inspection priority corresponding to the welding infirm is 3 level, wherein the 1 level inspection priority is higher than the 2 level inspection priority, and the 2 level inspection priority is higher than the 3 level inspection priority.

According to the information tracing method provided by the embodiment, the corresponding investigation priority is set according to the abnormal hazard level of the abnormal target product corresponding to each abnormal association result, so that the tracing investigation efficiency of the abnormal target product with serious problems is improved.

In one implementation manner of the present embodiment, as shown in fig. 5, in step S204, after obtaining the production lot of the abnormal target product and the docking client as the abnormality detection feedback if the circulation status is the factory, the method further includes the following steps:

s501, if the same production batch corresponds to a plurality of docking clients, obtaining the target duty ratio of each docking client to receive an abnormal target product in the same production batch;

s502, combining the target duty ratio and the abnormal characteristics corresponding to the abnormal target product to generate an abnormal traceability distribution map corresponding to the abnormal target product.

In step S501 to step S502, according to the situation that a plurality of butting clients receive the same production lot, the duty ratio of each client to receive the abnormal target product can be obtained, and then the abnormal characteristic of the abnormal target product is combined to generate an abnormal traceability distribution map, so that the specific distribution of the abnormality in the client group can be better known and checked through the abnormal traceability distribution map.

Specifically, for the abnormal target products in the same production batch, the distribution condition of each abnormal target product in the batch in different customers can be further known by acquiring the quantity and the proportion of the abnormal target products received by each butting customer.

For example, FPC flexible circuit board of production lot 01 has two abnormal target products of material selection problem and printing process problem, in which customer a receives 50% of the circuit boards of material selection problem, customer B receives 30% of the circuit boards of material selection problem and 40% of the circuit boards of printing process problem, and customer C receives 20% of the circuit boards of printing process problem.

Further, an anomaly traceback distribution map is generated by integrating the anomaly target product and its distribution in each of the interfacing clients. For example, the material selection problem accounts for 80% of the 01 production batch, and the printing process problem accounts for only 20% of the 01 production batch, wherein the abnormal characteristic corresponding to the material selection problem is that the conductive adhesive quality provided by the supplier M is not too close, and the abnormal characteristic corresponding to the printing process problem is that the printing machine parameter is set abnormal, so that the problem cause can be found in a targeted manner and improved in time through the abnormal tracing distribution diagram, and the production efficiency and the product quality of the product are improved.

According to the information tracing method provided by the embodiment, the source and distribution situation of the problem of the abnormal target product can be more intuitively understood and mastered according to the abnormal tracing distribution diagram, so that the abnormal target product can be traced timely and accurately, and the tracing effect on the abnormal target product is improved.

In one implementation manner of the present embodiment, as shown in fig. 6, in step S107, if the information status is identified as abnormal, the method further includes the following steps after obtaining the abnormal circulation node of the target product:

s601, acquiring an abnormality detection parameter corresponding to an abnormality circulation node;

s602, identifying abnormal detection parameters and obtaining abnormal processing points corresponding to a target product;

s603, if the abnormal machining points are multiple; judging whether correlation exists between abnormal machining points;

s604, if correlation exists among the abnormal processing points, acquiring corresponding target related processing points, and generating an abnormal correlation analysis report corresponding to the abnormal flow node according to the correlation coefficient among the target related processing points.

In steps S601 to S602, according to each node of the abnormal target product in the production process, a corresponding abnormality detection parameter may be obtained. And then, by identifying the abnormality detection parameters, the abnormal processing point positions of the target product can be rapidly positioned, wherein the abnormal processing point positions refer to all processing nodes contained in the abnormal circulation nodes in the production process of the product, the reasons of occurrence of the abnormality are further analyzed, and corresponding measures are taken for improvement and optimization.

For example, the abnormal circulation node corresponding to the FPC flexible circuit board is copper plating, and the corresponding abnormal detection parameters comprise cleaning time and gold plating temperature which are not up to standard, wherein the abnormal processing point corresponding to the unqualified cleaning time is cleaning, and the abnormal processing point corresponding to the unqualified gold plating temperature is gold plating.

Specifically, if the detection parameter of a certain abnormal circulation node is not in accordance with the requirement, that is, the abnormal detection parameter appears, the number of abnormal target products of the node is increased, and the point position of the abnormal target product, where the processing abnormality appears, can be determined by identifying the abnormal detection parameter, so that the reason of the abnormality is better analyzed.

For example, in the drilling link of the flexible printed circuit board (FPC), when the abnormal processing point position with low bit precision is detected, the product processed by the abnormal processing point position can be determined, and a certain amount of circuit boards with inaccurate drilling positions, namely, abnormal target products, exist, so that the generation of subsequent abnormal target products can be reduced through the determination and correction of the abnormal processing point position, namely, the correction of the bit precision.

In step S603 to step S604, if there are a plurality of current abnormal machining points, it is determined whether there is a correlation between the abnormal machining points in order to perform deep analysis on each abnormal machining point.

Specifically, if there is a certain relationship or dependency relationship between different processing nodes, they will affect each other when a problem occurs, resulting in an increase in the number of abnormal target products, and therefore, it is necessary to determine whether there is a correlation between a plurality of processing nodes.

For example, in the manufacturing process of the flexible circuit board of the FPC, if the drilling accuracy is insufficient and the thickness of the printed coating is uneven, which may cause poor connection of the wires or a short circuit problem, it may be determined that there is a correlation between the drilling, the printing, and the connection of the wires.

Further, if there is a correlation between the above-mentioned processing points, in order to trace back the specific cause and influence range of the occurrence of the abnormality in depth, the correlation coefficient and the degree of correlation between the points are further analyzed.

For example, assuming that some circuit boards with poor wire connections are found in a production lot, further analysis finds that these circuit boards are mostly from the same process flow. Through calculation and analysis of the correlation coefficient between the drilling and printing links, the correlation degree between the drilling and printing links can be found to be very high, namely obvious correlation exists. At the moment, an abnormal correlation analysis report can be generated, so that manufacturers can find out the problem sources and take corresponding measures to improve. Wherein, the drilling and printing links can be calculated and analyzed through the Pearson correlation coefficient.

According to the information tracing method provided by the embodiment, the root cause and influence factors of the problem of the abnormal target product can be more accurately known and mastered according to the abnormal correlation analysis report, so that the problem tracing and processing efficiency of the abnormal target product is improved.

In one implementation manner of this embodiment, as shown in fig. 7, in step S602, that is, identifying an abnormality detection parameter, after obtaining an abnormality processing point corresponding to a target product, the method further includes the following steps:

s701, if the abnormal machining point is single; judging whether the abnormal machining point position comprises a plurality of abnormal machining procedures or not;

s702, if the abnormal processing point position comprises a plurality of abnormal processing procedures, acquiring the abnormal triggering frequency and the abnormal triggering cause of each abnormal processing procedure;

s703, combining the abnormality induction frequency and the abnormality cause to generate an abnormality traceability report corresponding to the abnormal processing point.

In step S701, if the abnormal processing point is single, the abnormal processing point may include a plurality of steps, and each step may be a point of occurrence of an abnormal target product, so that it is necessary to further analyze whether the abnormal processing point includes a plurality of steps.

For example, the abnormal processing point of the FPC flexible circuit board in the copper plating process is electroless copper plating, which comprises processing procedures of substrate surface treatment, pretreatment, electroless copper plating, washing and drying, and the abnormal processing procedures are obtained and judged if the abnormal processing points indicate that the substrate surface treatment and pretreatment are abnormal, i.e. not up to standard.

In steps S702 to S703, in order to trace the problem and analyze the abnormality for a specific abnormal processing step, the abnormality occurrence frequency and abnormality cause of each abnormal processing step are obtained. The abnormal initiation frequency refers to the frequency of similar abnormality in the obtained history of abnormal processing procedures, and the abnormality cause refers to the cause of inducing the abnormality in the processing procedures.

For example, the abnormal working process is a substrate surface treatment and pretreatment, the substrate surface treatment means that the surface of the substrate needs to be cleaned, deoxidized and activated before electroless copper plating is performed, so that the surface is clean, smooth and has good adhesion, the substrate pretreatment means that the substrate needs to be pretreated after the surface treatment is completed so as to better receive a metal coating, and the substrate surface treatment method includes immersing, spraying or brushing a layer of a suitable solution, such as an acidic detergent, and rinsing after a certain time has elapsed so as to remove the surplus substances.

Further, the inspection of the system shows that the surface of the substrate is not in accordance with the acceptance criteria of the two processing procedures after the treatment and the pretreatment, wherein the abnormal induction of the processing procedure of the surface treatment of the substrate is incomplete in surface oil stain removal, the abnormal induction of the surface pretreatment of the substrate is unreasonable in temperature control, the history of the processing procedure of the surface treatment of the substrate is obtained through the log record of the system, the abnormal induction of the surface treatment of the substrate is 2 times, and the abnormal processing of the surface pretreatment of the substrate is 5 times. And then combining the abnormality induction frequency and the abnormality cause to generate an abnormality tracing report corresponding to the abnormal processing point position, and intuitively reflecting which abnormal processing procedures currently occur and the cycle frequency of the same type of abnormality occurrence of each abnormal processing procedure through the abnormality tracing report.

According to the information tracing method provided by the embodiment, the anomaly induction frequency and the anomaly cause corresponding to the anomaly processing procedure are comprehensively analyzed, and the anomaly processing procedure can be accurately and qualitatively performed, so that the problem tracing and processing efficiency of the anomaly processing point positions are improved.
