Description

Technical Field

[0001] The present invention relates to the field of FCBGA packaging substrates, and in particular to a CAM tool data conversion method, device and storage medium. Background Art

[0002] In the production process of semiconductor packaging substrates, a substrate needs to go through multiple processes. Different processes correspond to different processing data and processing equipment. Due to the particularity of the processing equipment, there is a need to convert the processing data corresponding to the process into data that can be read by the corresponding processing equipment. For example, in the laser drilling process, laser drilling is achieved by Mitsubishi laser drilling equipment. Due to the particularity of Mitsubishi laser drilling equipment, before production, the CAM tool data provided by the CAM department needs to be converted into a processing formula that can be recognized by the Mitsubishi laser drilling equipment using Mitsubishi conversion software. Among them, the CAM department is a computer-aided manufacturing department, which is used to output CAM tool data to subsequent departments through design software. Design software is software used in packaging substrates to output CAM tool data according to customer drawings.

[0003] The existing conversion method is manual conversion. The disadvantages of this conversion method are: first, because the CAM department and the laser drilling department are in different production departments, when the CAM department updates the CAM tool data, the laser drilling department cannot know the update information in time, and the staff cannot operate in time, resulting in untimely update of the CAM tool data version, causing production delays, and more seriously, it may cause the substrate to be scrapped, increasing production costs; second, during the conversion, the staff manually sets the conversion parameters and manually calls the conversion parameters. If the operator makes a mistake, the conversion parameters are set incorrectly or the call parameters are wrong, which will cause the substrate to be scrapped; third, during the production of Mitsubishi laser drilling machines, the staff needs to manually input the workpiece thickness value, workpiece expansion and contraction value, CCD number and other variable values ​​into the drilling equipment in advance. During the input, if the operator makes a mistake and the input is wrong, it will cause the equipment to alarm. Based on the above disadvantages, the existing manual conversion of CAM tool data not only has high personnel costs, but also low labor efficiency and production efficiency. The scrapping of the substrate caused by errors will also increase production costs. Summary of the invention

[0004] In order to overcome the defects in the prior art, the embodiments of the present invention provide a CAM tool data conversion method, device and storage medium, which can improve conversion accuracy, improve production efficiency and reduce production costs.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is: The first aspect of the present invention discloses a CAM tool data conversion method, comprising the following steps: Acquire CAM tool data to be converted, wherein the CAM tool data includes processing data of at least one process type; According to the process type in the processing data, corresponding process parameters are extracted from a preset database, and the process parameters are written into the CAM tool data, wherein the process parameters include a process type identifier and value information; According to a preset storage path and naming rules, the CAM tool data after the process parameters are written is saved to a conversion program, wherein the conversion program pre-stores a plurality of conversion parameters named according to different process type identifiers; Based on the process type identification in the CAM tool data, matching the conversion parameters consistent with the process type identification name in the conversion program; The conversion program converts the processing data into a processing formula recognizable by the target device based on the matched conversion parameters; The quantity information is converted into target information recognizable by the target device, and the target information is written into the processing formula.

[0006] The above technical solution adjusts the manual conversion and input of process parameters in the prior art to automatic identification and writing of process parameters, thereby automatically writing the process parameters corresponding to the process type into the CAM tool data, automatically identifying the process type identifier and the corresponding conversion parameters, and automatically converting the measurement information into target information recognizable by the target device, thereby realizing the automatic conversion of the processing data in the CAM tool data into the processing formula, which can reduce the conversion error rate caused by manual participation, improve processing efficiency, and reduce production costs.

[0007] Furthermore, the process type is a drilling process, and the process parameters are drilling parameters, wherein: The process type identification includes: partition drilling process, non-partition drilling process, and X-via process; The measurement information includes: plate thickness value, expansion and contraction value, component number, and number of drilled holes.

[0008] Furthermore, according to the process type in the processing data, corresponding process parameters are extracted from a preset database, and the process parameters are written into the CAM tool data, wherein the process parameters are written into a comment area of ​​the CAM tool data.

[0009] Writing process parameters into the comment area, on the one hand, facilitates the subsequent identification and acquisition of process parameters; on the other hand, when reviewers review the converted processing formula, they can check whether the information before and after the conversion is correct based on the content of the CAM tool data comment area, such as whether the number of holes is consistent, whether the process type called during automatic conversion matches, and whether the automatically written value information is correct. This can improve review efficiency, prevent mistakes, avoid conversion errors due to BUG problems, improve conversion success, and further improve production efficiency.

[0010] Furthermore, the step of "saving the CAM tool data after writing the process parameters to the conversion program according to the preset storage path and naming rules, wherein the conversion program pre-stores a plurality of conversion parameters named according to different process type identifiers" also includes: The CAM tool data after the process parameters are written is stored in a folder of a preset storage path, and the preset storage path and the name of the folder are sent to the conversion program, and the name of the folder is consistent with the name of the CAM tool data; Based on the preset storage path and the name of the folder, the conversion program accesses the folder and obtains the CAM tool data after the process parameters are written into the folder.

[0011] By automatically storing the CAM tool data after the process parameters are written according to the preset storage path, and the conversion program automatically accesses and obtains the CAM tool data after the process parameters are written, it is possible to realize the automatic transmission and reception of the CAM tool data. Even if the subsequent production department is unable to know the update of CAM tool data information in time, it is also possible to timely adjust and update the processing formula and the value information within the processing formula, which can avoid the situation where different processes cannot receive information in time due to information difference, and can avoid the scrapping of substrates due to information difference caused by manual participation, thereby improving processing efficiency.

[0012] Furthermore, the step of “matching conversion parameters consistent with the process type identification name in the conversion program based on the process type identification in the CAM tool data” also includes: Identify the process type identifier in the CAM tool data; According to the identified process type identifier, a conversion parameter consistent with the process type identifier name is identified from the conversion program.

[0013] By converting the manual input of conversion parameters into automatic identification and matching of conversion parameter names in the conversion program, the conversion efficiency and accuracy can be improved, and conversion errors caused by human operating errors can be avoided.

[0014] Furthermore, the step of "the conversion program converts the processing data into a processing formula recognizable by the target device based on the matched conversion parameters" also includes: After the match is successful, output a start instruction to the conversion program; Based on the start instruction, the conversion program is started and the conversion parameters are called.

[0015] By adjusting the method of manually inputting and calling out conversion parameters for conversion to a method of starting the conversion program upon receiving a start instruction, no manual operation is required, thereby reducing the conversion error rate.

[0016] Furthermore, the step of “converting the quantity information into target information recognizable by the target device, and writing the target information into the processing formula” also includes: The measurement value information in the CAM tool data is obtained, and a preset instruction is added before the measurement value information to generate the target information.

[0017] By converting the manual input of quantity value information into automatically converted target information and writing it into the processing formula, manual input is no longer required, which can reduce the error rate of input information and improve production efficiency.

[0018] Furthermore, the step of "converting the measurement information into target information recognizable by the target device, and writing the target information into the processing formula" also includes: storing the processing formula written with the target information into a folder of a preset storage path. Thus, the target device can automatically recognize and obtain the processing formula and target information according to the preset path during production.

[0019] The second aspect of the present invention discloses a CAM tool data conversion device, which includes a memory and a processor. The memory stores a program, and the program is loaded and executed by the processor to implement the method described in any one of the first aspects.

[0020] A third aspect of the present invention discloses a computer storage medium, wherein at least one program instruction is stored in the computer storage medium, and the at least one program instruction is loaded and executed by a processor to implement any method as described in the first aspect.

[0021] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: The present application automatically writes the process parameters corresponding to the process type into the CAM tool data, automatically identifies the process type identifier and the corresponding conversion parameters, and converts the measurement information into target information that can be recognized by the equipment. There is no need for manual conversion and input of process parameters. It can realize the automatic conversion of process information in the CAM tool data into processing formulas, reduce the conversion error rate caused by manual participation, improve processing efficiency, and reduce production costs.

[0028] Reference Figure 1 As shown, the embodiment of the present application provides a CAM tool data conversion method, comprising the following steps: Step 101, obtaining CAM tool data to be converted, wherein the CAM tool data includes processing data of at least one process type.

[0029] The CAM tool data is the computer digital control tool data in the packaging substrate, which is the information required for substrate production and is used to instruct substrate production. The packaging substrate needs to go through multiple processes during the production process. The CAM tool data includes a variety of processing data corresponding to the multiple processes. The processing data is the specific processing content for implementing the current process.

[0030] The CAM tool data to be converted includes CAM tool data being produced and completed. In an embodiment of the present application, the CAM tool data to be converted is CAM tool data being produced, wherein the entire cycle from the start of production to the completion of production of the CAM tool data belongs to the CAM tool data being produced. By acquiring the CAM tool data currently being produced, the execution of data conversion is triggered.

[0031] According to the process difficulty of CAM tool data and the different production cycles of different CAM tool data, obtaining the CAM tool data currently being produced can detect and monitor the production process of the CAM tool data, adjust the conversion steps of the CAM tool data in time, and update the process information in time.

[0032] Specifically, when it is detected that the CAM tool data starts to be produced, step 101 and step 102 are executed, and when it is detected that the CAM tool data is completed, the subsequent steps are executed. The start of the CAM tool data production includes modifying and adjusting the CAM tool data, and the nodes of the start and completion of the CAM tool data production can be set according to actual conditions.

[0033] Step 102, according to the process type in the processing data, extract corresponding process parameters from a preset database, and write the process parameters into the CAM tool data, wherein the process parameters include a process type identifier and value information.

[0034] The preset database is a database that stores all substrate design information. In an embodiment of the present application, when the CAM tool data is started to be produced, the process parameters of the processing data required for one of the process processes in the CAM tool data currently being produced are obtained from the preset database and written into the CAM tool data.

[0035] Optionally, the process parameters are written into the comment area of ​​the CAM tool data, which can avoid affecting the content of the CAM tool data and can be identified, and is also convenient for reviewers to check later.

[0036] Optionally, the process type is a drilling process, and the process parameters are drilling parameters, wherein the process type is a classification of the process, which can be understood as the name of the processing data. When the substrate is different, the process type is different, and the processing value information is also different.

[0037] The process type identifier is a name that is further subdivided into process types. In the embodiment of the present application, the process type identifier includes: The partition drilling process divides the substrate into multiple different areas according to production requirements, and then drills the same type of holes or different types of holes in the different areas.

[0038] The non-partitioned drilling process does not partition the substrate, but directly drills holes at designated locations on the substrate.

[0039] X-via process, that is, laser hole process, such as HDI laser hole.

[0040] The quantity information includes: Board thickness value, the overall thickness of the substrate.

[0041] Expansion and shrinkage value refers to the numerical value of the dimensional expansion or contraction of the substrate under specific influencing factors.

[0042] Device number, the number of the equipment that processes the substrate, such as the number of a CCD drilling rig.

[0043] Drill hole count, the number of drill holes formed on the substrate during the drilling process.

[0044] It should be noted that the process type identification and measurement value information in the above embodiment is only one embodiment shown in this application. Depending on the processing technology and equipment, the process type identification and measurement value information that need to be converted are also different. For example, in other drilling equipment, the drilling size needs to be converted, and the variable value information also includes the drilling size. This application will not describe it in detail here.

[0045] Step 103, according to a preset storage path and naming rule, the CAM tool data after the process parameters are written is saved to a conversion program, wherein the conversion program pre-stores a plurality of conversion parameters named according to different process type identifiers.

[0046] The conversion program is a program that converts at least one processing data in the CAM tool data into data that can be recognized by the corresponding equipment, and the conversion parameter is the conversion information stored in the conversion program for converting at least one processing data into data that can be recognized by the corresponding equipment. Since different process conversion parameters are also different, naming the conversion parameters according to the process type name can more conveniently call out the conversion parameters, which is convenient for the reviewer to subsequently review whether the converted processing formula is correct, avoid conversion errors caused by BUG problems, and improve the conversion success rate.

[0047] Specifically, according to the preset storage path and naming rules, the CAM tool data after the process parameters are written is saved to the conversion program, which also includes: The CAM tool data after the process parameters are written is stored in a folder of a preset storage path, and the preset storage path and the name of the folder are sent to the conversion program, and the name of the folder is consistent with the name of the CAM tool data; Based on the preset storage path and the name of the folder, the conversion program accesses the folder and obtains the CAM tool data after the process parameters are written into the folder.

[0048] The CAM tool data after the process parameters are written include the CAM tool data being produced and the CAM tool data that has been produced. In an embodiment of the present application, the CAM tool data after the process parameters are written is the CAM tool data that has been produced.

[0049] The preset storage path is a pre-specified storage path, usually a fixed path, and all the completed CAM tool data are stored in this path, so that there are multiple folders in this path, and the folder names are named according to the names of the completed CAM tool data, so that the conversion program can recognize and obtain the data therein. For example, when the name of the completed CAM tool data is 001, the name of the current folder is 001.

[0050] Step 104, based on the process type identifier in the CAM tool data, matching the conversion parameters consistent with the process type identifier name in the conversion program.

[0051] Specifically, this step also includes: Identify the process type identifier in the CAM tool data; According to the identified process type identifier, a conversion parameter consistent with the process type identifier name is identified from the conversion program.

[0052] Different processes have different names. In specific implementation, the currently identified process type identifier is matched with the name of the identified conversion parameter. If the names are consistent, the currently identified conversion parameter is the conversion parameter that can convert the current processing data.

[0053] In an embodiment of the present application, the conversion parameters in the conversion program are classified according to the drilling process type and are the same as the name of the drilling process type. For example, if the name of the partitioned drilling process in the CAM tool data is "3M-FQSK-T500", then the process type identifier identified in the comment area of ​​the CAM tool data is "3M-FQSK-T500". According to the process type identifier of "3M-FQSK-T500", the conversion parameter named "3M-FQSK-T500" is identified from the multiple conversion parameters in the conversion program. If the names of the two are consistent, the match is successful, and the conversion parameter named "3M-FQSK-T500" is called out.

[0054] Step 105 , the conversion program converts the processing data into a processing formula recognizable by the target device based on the matched conversion parameters.

[0055] The target device is a device for processing the current process, and the processing formula is processing data that can be recognized and used by the device for processing the current process. In an embodiment of the present application, the target device is a drilling machine for processing the drilling process, and the conversion program is used to convert the drilling data corresponding to the drilling process in the CAM tool data into a processing formula that can be recognized by the drilling machine.

[0056] Specifically, this step also includes: After the match is successful, output a start instruction to the conversion program; Based on the startup instruction, the conversion program is started, the conversion parameters are called, and the conversion is performed to convert the processing data into a processing formula that can be recognized by the target device.

[0057] Through the above steps, the manual setting and calling of conversion parameters are transformed into automatic identification of conversion parameters, which can reduce the error rate and improve production efficiency.

[0058] Step 106: convert the quantity information into target information recognizable by the target device, and write the target information into the processing formula.

[0059] Since different substrates correspond to different measurement information, these variable measurement information cannot be pre-stored in the conversion parameters for synchronous conversion. Therefore, after the processing formula conversion is completed, the measurement information needs to be separately input into the processing formula.

[0060] Specifically, this step also includes: The measurement value information in the CAM tool data is obtained, and a preset instruction is added before the measurement value information to generate the target information.

[0061] Furthermore, it also includes: storing the processing formula written with the target information in a folder of a preset storage path. The processing formula and the completed CAM tool data are stored in the same folder, and when the equipment is processing, it automatically identifies and obtains the processing formula in the current folder for processing.

[0062] The preset instructions are information that can be recognized by the equipment for the current processing process. For example, the measurement information obtained from the CAM tool data is the plate thickness value, expansion and contraction value, device number, and the number of processing holes. Then, the preset instruction #621 is added before the plate thickness value, the preset instruction #592 is added before the expansion and contraction value, and the preset instruction #593 is added before the device number such as the CCD (equipment optical system) number. Then, the instructions and measurement information are written into the processing formula. When the drilling machine is in production, the drilling machine automatically recognizes the instructions written into the processing formula and performs production.

[0063] It should be noted that different devices can recognize different instructions. The instructions shown in the embodiments of the present application are only used as an example for illustration and are not intended to limit the instructions.

[0064] Through the above steps, the manually input value information is transformed into automatically acquired value information and then converted into target information recognizable by the processing equipment, which can reduce the error rate and improve production efficiency.

[0065] The present application also provides a CAM tool data conversion device, which includes a memory and a processor. The memory stores a program, and the program is loaded and executed by the processor to implement the method as described above.

[0066] The present application also provides a computer storage medium, in which at least one program instruction is stored. The at least one program instruction is loaded and executed by a processor to implement the method described above.

[0067] The present invention uses specific embodiments to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
