According to different quality tracing requirements and structural characteristics of different products, a corresponding two-dimensional code can be respectively allocated to all the constituent units of the product in the step, and partial constituent units needing quality tracing can be selected to be allocated with the two-dimensional code.
And 102, when entering a first designated procedure in the processing flow, converting the two-dimensional code of each component unit into a hole array code and drilling the hole array code on the component unit.
The hole array code is used for marking information to be recorded by combining position information of a plurality of small holes in a specified area. The hole array code and the two-dimensional code correspond to each other one by one and have uniqueness. When the hole array code is formed, a through hole can be drilled, and a blind hole can also be drilled.
The first designated step may be any one of the steps designated in the process flow, and is not limited to the first step in the process flow. In a specific implementation, the earliest step in the processing flow, which may adversely affect the two-dimensional code recognition, may be designated as the first designating step.
The second specifying step may be a step in which a plurality of constituent units are combined and integrated, and in this case, information of the inner layer needs to be transferred to the outer layer.
In the step, different hole array codes of all the composition units in the inner layer can be read at one time through the X-Ray, so that the hole array codes can be transferred from the inner layer to the outer layer quickly, the process is simplified, and the efficiency is improved.
And 104, when entering a third designated procedure in the processing flow, reading the hole array code on the combined structure, converting the hole array code into a corresponding two-dimensional code, and then arranging the two-dimensional code on the combined structure.

Locate the product skin again after changing the hole array code back two-dimensional code, for the hole array code, it reads to be more convenient.
This embodiment is directed at the product that is formed by a plurality of constitutional units according to the processing procedure processing of predetermineeing, traces back the appearance mode that the sign adopted interconversion's two-dimensional code or hole array code, can enough solve some processes and produce the problem of harmful effects to the two-dimensional code discernment, can solve the problem that inlayer information loses again.
In addition, the tracing method further includes: creating a record item corresponding to each two-dimensional code at a server, wherein each two-dimensional code is used for binding various production related information of a corresponding component unit or a combined structure in the whole processing flow; for each composition unit and each composite structure, when any procedure in the processing flow is carried out, the hole array codes or the two-dimensional codes on the current composition units and the composite structures are read, and the current production related information is synchronized to the corresponding record items of the server side. Therefore, quality monitoring of the whole process can be realized, and forward tracing and reverse tracing are facilitated.
The quality tracing method of the embodiment can be applied to products in various fields, such as a PCB and an FPC, and is not particularly limited, and the method can be applied as long as the defects that the two-dimensional code is not easily recognized and/or inner layer information is easily lost when the two-dimensional code is used as a tracing identifier are possibly involved. When the method is applied to different products, the specific procedures indicated by the first, second and third specifying procedures may be set according to the actual processing flow of the current product.
The following provides an application example to further illustrate the technical solution of the present invention.
Referring to fig. 2, the present embodiment provides a quality tracing method for a multilayer PCB, including the following steps:

When the hole array code is formed, a through hole can be drilled, and a blind hole can also be drilled. Compared with the method of drilling through holes, the method of drilling blind holes has the advantages of small equipment investment, low cost, high efficiency, high automation degree and the like.
In addition, in order to ensure the normal manufacture of the core plate, the hole array codes can be arranged at the plate edges of the core plate. Meanwhile, in order to avoid mutual interference among the hole array codes of a plurality of core plates in the subsequent pressing process, different hole array code drilling areas need to be specified for each core plate in advance according to the preset stacking layers, so that the hole array codes of the core plates in different layers are strictly partitioned, and the core plates are convenient to recognize and read.
Because the two-dimensional code generated for the multilayer board in the laminating process corresponds to the plurality of hole array codes, namely corresponds to the two-dimensional codes of the plurality of inner-layer core boards, the recorded information of the two-dimensional code of the multilayer board is the sum of the recorded information of the two-dimensional codes of the plurality of inner-layer core boards.
In the step, different hole array codes of the core plates of the inner layers can be read at one time through the X-Ray, so that the hole array codes can be transferred from the inner layer to the outer layer quickly, the process is simplified, and the efficiency is improved.
When each core board/multilayer board passes through each processing device applied in the process, the hole array code is read through the CCD, and the current production related information is synchronized to the corresponding record item of the server side.

And step 206, entering other subsequent procedures including surface treatment, forming, electrical measurement, FQC/FQA, packaging and the like, reading the two-dimensional code on the multilayer board through a scanning gun when the multilayer board passes through one processing device every time, and synchronizing the current production related information into a corresponding record item of a server side.
In the above flow, since the two-dimensional code is not easily recognized due to being easily covered or etched in the character printing process and the processes before the character printing process, the two-dimensional code is converted into the hole array code and formed on the board in the meantime; and after the characters printing process, the factors which have adverse effects on the two-dimensional code disappear, so the hole array code is converted back to the two-dimensional code to be formed on the board after the characters are printed, and the two-dimensional code can be quickly read through a scanning gun in the subsequent processes. Moreover, in the pressing process, the information of each inner layer can be quickly transferred to the outer layer, so that the loss of the information of the inner layers is prevented, and the integrity of data is effectively ensured.
In the whole process, each time the processing equipment passes through, the hole array code/two-dimensional code on the board is read, and the production related information is synchronized to the server side, and the production related information can comprise any one or any combination of a factory name, a process name, a production material number, a production batch number, an operator name, a production line name, production time, a name/supplier/batch number of raw materials, detection data and production parameters, so that comprehensive and complete data can be obtained at the server side, full life cycle tracing (including forward tracing and reverse tracing) of the product can be realized, quality monitoring of the full process of the product is enhanced, real-time monitoring of the processing equipment can be realized, and increasingly strict quality requirements on the market are met.
Example two

The first designated step may be any one of the steps designated in the process flow, and is not limited to the first step in the process flow. In a specific implementation, the earliest step in the processing flow, which may adversely affect the two-dimensional code recognition, may be designated as the first designating step.
In this case, the second specifying step may be any step that does not adversely affect the two-dimensional code at a later stage in the processing flow. Locate the product skin again after changing the hole array code back two-dimensional code, for the hole array code, it reads to be more convenient.
In addition, the quality tracing method of the embodiment further includes: creating a record item corresponding to each two-dimensional code at a server, wherein each two-dimensional code is used for binding various production related information of a corresponding product in the whole processing flow; for each product, when the product passes through any procedure in the processing flow, the hole array code or the two-dimensional code on the current product is read, and the current production related information is synchronized to the corresponding record item of the server side. Therefore, quality monitoring of the whole process can be realized, and forward tracing and reverse tracing are facilitated.
This embodiment is directed at by the non-combination product that forms according to predetermined processing procedure processing, traces back the presentation mode that the sign adopted interconversion's two-dimensional code or hole array code, can effectively solve some processes and produce the problem of harmful effects to the two-dimensional code discernment, guarantees to trace back the accurate discernment of sign.
