Description

Technical Field

[0001] The present invention belongs to the technical field of electronic material information management, and in particular relates to an electronic material coding method and system based on a combination of classification codes and description codes. Background Art

[0002] In the production of electronic products, electronic components need to be soldered on printed circuit boards (PCBs). Electronic components usually include capacitors, resistors, inductors, ferrite beads, chips, connectors, etc. These electronic components and semi-finished and finished PCBs are collectively referred to as electronic materials. The relevant information of the electronic materials used in production needs to be accurate and easy to read.

[0003] Before manufacturing various products, electronic materials must be purchased according to a bill of materials (BOM). To ensure unified and information-based management, these purchased electronic materials must be coded and labeled accordingly. Currently, in the field of electronic material information management, purely digital coding often uses serial numbers. While this method is simple and fast, and effectively avoids the problem of multiple material codes corresponding to the same material, it lacks legibility. Furthermore, if synchronization is not timely, it can easily lead to duplicate material codes, causing confusion in the manufacturing process.

[0004] Therefore, this field needs an intuitive, universal and efficient coding method that can generate a set of universal pure digital non-serial number codes based on the nominal values of different materials. This coding method can generate the same and unique code for the same material and can intuitively read the material properties. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to address the deficiencies in the above-mentioned prior art and provide an electronic material coding method and system based on a combination of classification codes and description codes, so as to solve the technical problems of lack of readability and easy duplication of traditional serial number codes.

[0006] The present invention adopts the following technical solutions: A method for electronic material coding based on a combination of classification codes and description codes comprises the following steps: Formulate coding rules based on the types, nominals, and packaging of commonly used electronic materials; receive bills of materials based on the coding rules; According to the material type and coding rules, give the classification code of each material in the received material list; Then determine the description code type based on the coding rule table of the description code corresponding to each material classification code; Based on the description code type, the material category is determined by encoding and comparing with the coding rule table.

[0007] Preferably, coding rules are formulated based on the types, nominals, and packaging of commonly used electronic materials; and a bill of materials is received according to the coding rules, specifically: Set the material code to eleven pure Arabic numerals, of which the first three are the material classification code, the next eight are the description code, and the last digit is reserved for the manufacturer number. If no manufacturer is specified, the default value is 0; According to the determined classification code, a coding rule table is formulated for the last eight description codes. Each classification code corresponds to a coding rule table. A coding rule table can correspond to multiple classification codes. There are two types of coding rules, namely nominal value coding + general attribute coding, and model coding + serial number coding.

[0008] Preferably, the bill of materials includes the type, quantity, tag number, nominal value, and packaging of the material.

[0009] Preferably, the nominal value encoding digits are three or four digits, which are the resistance value of the resistor and the capacitance value of the capacitor. The nominal value specifies the basic unit, and the nominal value in the bill of materials is expressed in scientific notation. The last digit of the nominal value is the weight, which is encoded as a specific power of 10, and the first few digits of the nominal value are the significant digits in scientific notation. The number of bits for general attribute encoding is one, 0 to 9 represents ten different common values of an attribute, encoding three or four attributes, including nominal value accuracy, surface mount package, withstand voltage, power, and current.

[0010] Preferably, for connectors, the model code is two digits long and is distinguished by serial numbers according to different uses, distinguishing 99 different types of connectors; For chips, the first five digits of the last eight digits of the description code are the model code, the sixth digit is the different packages of the same model, and the seventh digit is the serial number code of similar models; For finished PCBs, the last eight digits of the description code are the first two digits for the board type, the third digit for the board subcategory, the fourth and fifth digits for different iterative versions of the same board in the form of serial numbers, and the last three digits are reserved.

[0011] Preferably, the material category is determined based on the description code type by encoding and comparing with the encoding rule table, specifically: If the description code type obtained is nominal value coding + general attribute coding, encode the material according to the coding rule table. After encoding, compare it with the coding of existing materials in the database. If there is no identical code, add a new material, generate a corresponding code, and insert it into the database.

[0012] Preferably, if the same code already exists, it is classified as an existing material, and the inventory quantity is changed to obtain the material code.

[0013] Preferably, the material category is determined based on the description code type by encoding and comparing with the encoding rule table, specifically: If the description code type obtained is model code + serial number code, the database is searched for a completely matching nominal and package. If there is no complete match, a fuzzy search is performed on the closest material to determine whether it is an existing material. If there is no identical material, a new material is added, and the corresponding code is automatically generated and inserted into the database.

[0014] Preferably, if there is a completely matching nominal and packaging, the material is already available, and the inventory quantity is changed to obtain the material code.

[0015] In a second aspect, an embodiment of the present invention provides an electronic material coding system based on a combination of classification codes and description codes, including: The coding module formulates coding rules based on the types, nominals, and packaging of commonly used electronic materials; and receives the bill of materials according to the coding rules; The classification module gives the classification code of each material in the received bill of materials according to the material type and coding rules; The judgment module then determines the description code type according to the coding rule table of the description code corresponding to each material classification code; The output module determines the material category based on the description code type by encoding and comparing it with the coding rule table.

[0016] In a third aspect, a computer device comprises a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the computer program, the steps of the electronic material coding method based on the combination of classification codes and description codes are implemented.

[0017] In a fourth aspect, an embodiment of the present invention provides a computer-readable storage medium, comprising a computer program, which, when executed by a processor, implements the steps of the above-mentioned electronic material coding method based on a combination of classification codes and description codes.

[0018] In a fifth aspect, a chip comprises a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the computer program, the steps of the electronic material coding method based on the combination of classification codes and description codes are implemented.

[0019] In a sixth aspect, an embodiment of the present invention provides an electronic device, comprising a computer program, which, when executed by the electronic device, implements the steps of the above-mentioned electronic material coding method based on a combination of classification codes and description codes.

[0020] Compared with the prior art, the present invention has at least the following beneficial effects: An electronic material coding method based on a combination of classification codes and description codes. By dividing the codes into classification codes and description codes, the classification codes clearly define the type of material, and the description codes contain key parameters such as nominal values and packaging, so that the codes themselves carry semantic information and are easy to quickly identify manually; the description codes are standardized through a coding rule table to ensure that the attributes of the same material generate unique codes, avoiding different materials sharing the same code; the rule table supports dynamic expansion to adapt to new material types or parameter changes. For example, when adding chip packages or voltage resistance levels, only the rule table needs to be updated instead of reconstructing the coding system; structured coding is easy to integrate with ERP / MES systems to achieve full-process automation of material procurement, inventory management, and production traceability; material attributes are mapped to digital codes through the rule table, retaining the machine readability of pure numbers while reconstructing semantics through the rule table, balancing readability and system compatibility.

[0021] Furthermore, the code is limited to 11 pure digits and divided into classification code, description code and manufacturer code. The fixed length and structure simplify the system processing logic and avoid parsing errors caused by different code lengths; the last digit of the manufacturer code supports future supplier expansion and avoids the reconstruction of coding rules due to new manufacturers; different classification codes are allowed to share the same rule table to reduce redundant design.

[0022] Furthermore, it is clarified that the BOM must include the material type, quantity, tag number, nominal and packaging information to ensure the completeness of key attributes required for coding and avoid coding errors due to missing information; the tag number is associated with the PCB design drawing to support material traceability and fault analysis during the production process.

[0023] Furthermore, the encoding rules for nominal values and conventional attributes are standardized, scientific notation is used to unify the nominal value representation to avoid unit confusion, and one digit is used to encode multiple attributes to reduce the encoding length.

[0024] Furthermore, the coding rules for connectors, chips and PCBs are designed. Connectors use two-digit serial numbers to distinguish 99 types, adapting to their characteristics of few types but many variants; the first five digits of the chip retain the model code to support precise matching of complex models; the last three digits of the PCB serial number record the iterative version to facilitate tracing of production batches.

[0025] Furthermore, the uniqueness is ensured by comparing the nominal value + attribute code with the database. If the code does not exist, a new material is added; otherwise, the inventory is updated.

[0026] Furthermore, for materials with complex models, fuzzy searches for similar materials are allowed to reduce duplicate coding caused by slight differences in models.

[0027] It can be understood that the beneficial effects of the second to sixth aspects mentioned above can be found in the relevant description of the first aspect mentioned above, and will not be repeated here.

[0028] In summary, the method of the present invention has strong readability, high uniqueness, compatibility with automated management, flexible expansion, and support for production traceability, which significantly reduces management costs and error rates.

[0041] The present invention provides an electronic material coding method based on a combination of classification codes and description codes. The method formulates an 11-digit pure digital coding rule. The first three digits are the classification code, which distinguishes the material's patch / plug-in package, basic type, and specific category; the last eight digits are the description code, which is divided into two categories according to the material properties: for materials with nominal values, such as resistors and capacitors, a nominal value coding based on scientific notation conversion is used, combined with conventional attribute coding for precision, packaging, etc.; for materials without nominal values, such as chips and PCB finished products, a model code and serial number code are used. The classification code and description code are automatically generated by parsing the BOM, and are compared with the database to handle conflicts. The coding rule of the present invention is both intuitive and unique, effectively solving the problems of poor readability and easy duplication of traditional serial number coding, and significantly improving the efficiency and accuracy of electronic material management.

[0042] Example 1 The present invention provides an electronic material coding method based on a combination of classification codes and description codes, comprising the following steps: S1. Develop coding rules based on the types, specifications, and packaging of commonly used electronic materials. Construct an enterprise electronic material management system based on the coding rules and receive a Bill of Materials (BOM) from the user. The BOM contains the material type, quantity, tag number, specification, and packaging. S101. Set the material code to eleven pure Arabic numerals, of which the first three are the material classification code, the next eight are the description code, and the last digit is reserved for the manufacturer number. If no manufacturer is specified, the default is 0; In the material classification code, the first digit distinguishes between the surface mount package and plug-in package of the material, the second digit distinguishes the basic type of the material, and the third digit subdivides the specific type of the material.

[0043] The first digit of the classification code uses odd numbers to represent SMD components, and even numbers to represent plug-in components; The second digit distinguishes the basic types of materials, which include capacitors, resistors, inductors, magnetic beads, chips, etc. The third digit is the specific type of the same type, including different types of capacitors, different types of resistors, and burned and unburned chips, etc.

[0044] S102. According to the classification code determined in step S101, a coding rule table is formulated for the last eight description codes. Each classification code corresponds to a coding rule table. A coding rule table can correspond to multiple classification codes. The coding rules are divided into two types: nominal value coding + conventional attribute coding, and model coding + serial number coding.

[0045] Nominal value coding + general attribute coding is used for materials that require specific nominal values, such as resistors, capacitors, inductors, and ferrite beads.

[0046] Model code + serial number code is used for chips, transistors, diodes, etc. that are displayed as component models rather than nominal values in the BOM, as well as materials such as PCB finished products that cannot be described by nominal values.

[0047] The number of digits for encoding the nominal value is usually three or four, which is a specific digital code for the resistance value of a resistor, the capacitance value of a capacitor, etc. Specifically, the nominal value specifies the basic unit, and the nominal value in the BOM is expressed in scientific notation. The last digit of the nominal value is the weight, which is encoded as a specific power of 10, and the first few digits of the nominal value are the significant digits in scientific notation.

[0048] The power of the nominal value encoding is less than zero, and the weight is mapped, and the weight 0~6 represents 10 0 to 10 6 , weight 7 means 10 -3 , weight 8 means 10 -2 , weight 9 means 10 -1 , weights 0 to 9 ultimately represent 10 -3 to 10 6 .

[0049] The number of bits for general attribute encoding is one, 0 to 9 represents ten different common values of an attribute, and can be used to encode three or four attributes, including nominal value accuracy, surface mount package, withstand voltage, power, current, etc.

[0050] The model code usually has five digits. The model code is the first five digits of the component model, with letters deleted. If the number is less than five, zeros are added.

[0051] For connectors, the model code is two digits long and is distinguished in the form of serial numbers according to different uses, distinguishing up to 99 different types of connectors.

[0052] For chips, the first five digits of the last eight digits of the description code are the model code, the sixth digit is the different packages of the same model, and the seventh digit is the serial number code of similar models.

[0053] For finished PCBs, the last eight digits of the description code are the first two digits for the board type, the third digit for the board subcategory, the fourth and fifth digits for different iterative versions of the same board in the form of serial numbers, and the last three digits are reserved.

[0054] S2. For all materials in the BOM received in step S1, a classification code is given to each material according to the material type and coding rules; S3, judging the description code type according to the encoding rule table of the description code corresponding to the classification code obtained in step S2; S4. If the description code type obtained in step S3 is nominal value coding + general attribute coding, the material is coded according to the coding rule table. After coding, the material is compared with the coding of existing materials in the database. If the same code exists, the material is classified as an existing material, the inventory quantity is changed, and the material code is obtained. If there is no same code, the material is added, the corresponding code is automatically generated, and the new data is inserted into the database. S5. If the description code type obtained in step S3 is model code + serial number code, first search the database for a fully matching nominal and package. If a fully matching nominal and package already exists, it means the material is already available, and the inventory quantity is changed to obtain the material code. If there is no complete match, fuzzy search for the closest materials, and let the engineer manually determine whether it is an existing material. If there is no identical material, add a new material, automatically generate the corresponding code, and insert the new data into the database.

[0055] Those skilled in the art will appreciate that various aspects of the present invention may be implemented as systems, methods, or program products. Accordingly, various aspects of the present invention may be implemented in the following forms: entirely in hardware, entirely in software (including firmware, microcode, etc.), or in a combination of hardware and software, collectively referred to herein as "circuits," "modules," or "platforms."

[0075] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0076] Example 5 This embodiment provides a material coding rule generation method applied to the electronic material management link, as well as a complete coding example in which the last eight digits of the description code are a nominal value code + a conventional attribute code type.

[0077] S1. The material code consists of eleven pure Arabic numerals, of which the first three are classification codes, the last eight are description codes, and the last digit is reserved for the manufacturer number. If no manufacturer is specified, the default value is 0.

[0078] S2. The first three digits of the material code are the material classification code. The first digit distinguishes the surface mount package and plug-in package of the material, the second digit distinguishes the basic type of the material, and the third digit subdivides the specific type of the material.

[0079] See also Figure 1 The first digit of the three-digit classification code is used to distinguish between SMD and plug-in components. In this embodiment, 1 is a SMD component and 2 is a plug-in component. The second digit of the three-digit classification code is used to distinguish the basic type of material. In this embodiment, 1 is a capacitor. The third digit of the three-digit classification code is used to subdivide the specific type of material. In this embodiment, 0 to 9 are used to distinguish a total of 18 different types of capacitors, namely SMD and plug-in.

[0080] S3. According to the classification code determined in step S2, a coding rule table is formulated for the last eight description codes. Each classification code corresponds to a coding rule table, and a coding rule table corresponds to multiple classification codes.

[0081] See also Figure 2 ,for Figure 1 The description code rules of all 18 capacitors shown are as follows, except for SMD capacitor 118 and plug-in capacitor 217. Figure 2 As shown, there are 8 digits in total, including 4 nominal digits + 1 precision digit + 1 package digit + 1 withstand voltage digit + 1 manufacturer digit.

[0082] See also Figure 3 , Figure 3 Based on Figure 1 and Figure 2 The established rules are for a complete encoding example where the last eight digits of the description code are the nominal value code + the general attribute code. The material to be encoded is a chip capacitor with a nominal value of 680pF±5% 50V and a C0603 package. The first three digits of the classification code are 110. In the last eight digits of the description code, the nominal value is encoded as 680pF. The basic unit of capacitance is defined as nF. When written in scientific notation, 680pF = 6.8*10 2 pF=6.8*10 (-1) nF, with a weight of -1<0 and a mapping of 7, the 4-bit nominal value is coded as 6807; the 5th bit is ±5% accuracy, coded as 3; the 6th bit is 0603 package, coded as 3; the 7th bit is 50V withstand voltage, coded as 6; the 8th bit is unspecified manufacturer, coded as 0. Therefore, the complete 11-bit code for this part is 11068073360.

[0083] Example 6 This embodiment provides a complete coding example in which the last eight digits of the description code are the model code + the serial number code.

[0084] See also Figure 4 , Figure 4This is an example of a complete code where the last eight digits of the description code are the model code + serial number code. The type is an unprogrammed chip, and the first three digits of the classification code are 160. The last eight digits of the description code indicate the chip model is STM32F107RCT6, so the model code is 32107. The sixth digit indicates the package is LQFP64 10X10MM, the first package of this chip, and the package code is 1. The seventh digit indicates the first version of the chip, and the code is 1. The eighth digit indicates that the chip has no manufacturer specified, and the code is 0. Therefore, the complete 11-digit code for this material is 16032107110.

[0085] If the chip has two pre-programmed versions, and both Program A and Program B are pre-programmed, the chip type is a pre-programmed chip, and the first three digits are 161. The chip model and package in the last eight digits, i.e., digits 1 to 6, remain unchanged. If the 7th digit contains two pre-programmed versions, Program A is coded as 1 and Program B is coded as 2. Therefore, the complete 11-bit codes for the two different pre-programmed versions are 16132107110 and 16132107120.

[0086] In summary, the present invention provides an electronic material coding method and system based on the combination of classification codes and description codes. Through the pure digital coding rules of the combination of classification codes and description codes, the efficiency and accuracy of electronic material management are significantly improved. The classification code directly identifies the material type, and the description code is embedded in the nominal value, package and other key parameters. The meaning of the code can be quickly interpreted without relying on the database; the code is generated based on the rule table to ensure that the materials with the same attributes correspond to unique codes, and the problems of serial numbers being easily duplicated and "one item with multiple codes" are completely solved; the pure digital structure is adapted to the ERP / MES system, supporting automatic procurement, inventory warning and production batching, and reducing the risk of manual intervention; the classification code and the rule table are dynamically expanded to adapt to new material types or parameter changes, avoiding reconstruction of the coding system; the PCB version serial number, manufacturer code and attribute association design file realize full-link traceability and quickly locate quality problems; the nominal value is compressed by scientific notation, the unit is unified and the attribute code mapping is mapped, reducing human errors and training costs, and it is estimated to reduce management costs by 15% to 20%.
