Description

Technical Field

[0001] The present application relates to the field of PCB design, and more specifically, to a method for adjusting the direction of silk screen printing of PCB components, an electronic device and a storage medium. Background Art

[0002] The PCB (Printed Circuit Board) of electronic devices is generally made of multiple layers of copper foil and dielectric materials laminated together. With the increasing complexity of electronic products and the continuous increase in functional modules, there are more and more components on the PCB, especially some data center communication products, which have hundreds or thousands of components on a PCB board. Among these hundreds of components, some components need to be distinguished in direction during production and assembly. In order to guide production and assembly, component direction indicator symbols need to be placed on the PCB design to guide the placement direction of assembled components. This direction symbol is generally on the silk screen layer and is called component direction silk screen.

[0003] During PCB layout design, after the component package is placed, the component direction screen is manually adjusted according to the free area. PCB boards are usually small in size, and the default direction screen position and size of the component package on the board are generally not suitable, so manual adjustment is required. Since there may be dozens or hundreds of component direction screens on a PCB board, the manual adjustment workload is huge, resulting in low adjustment efficiency. Summary of the invention

[0004] The purpose of the present application is to provide a method for adjusting the direction silk screen of PCB components, an electronic device and a storage medium, which can improve the adjustment efficiency of the direction silk screen in the PCB board.

[0063] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0064] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0065] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0066] In the description of the present application, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear to indicate an orientation or position relationship, it is based on the orientation or position relationship shown in the drawings, or is the orientation or position relationship in which the product of the invention is usually placed when used. It is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0067] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0068] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0069] After extensive research, the inventors found that when making component packages, the component direction silk screen is made into a circular, triangular and other shapes, and placed near the predetermined pins of the package. When designing the PCB, when calling the component package, the component direction silk screen is imported at the same time. When designing the PCB layout, after the component package is placed, the component direction silk screen is manually adjusted according to the free area position. PCB boards are usually small in area, and the default direction silk screen position and size of the component package on the board are generally not adaptable, and manual adjustment is required. Manual adjustment includes changing the component direction silk screen position, reducing the component direction silk screen pattern, deleting the component direction silk screen, replacing the component direction silk screen pattern, and drawing a new component direction silk screen pattern.

[0070] This method is to manually complete the search, judgment, deletion, replacement, addition, pattern making and other tasks. Since a PCB board may have dozens or hundreds of component direction silk screens, the workload is huge. It is also easy to be negligent, resulting in unsightly component direction silk screens, mistaken deletion, missing placement, multiple placement, unreasonable patterns, and wrong position placement. The aforementioned errors will directly affect the production and processing of PCBA. In severe cases, it will cause the reflow soldering and wave soldering production lines of the processing factory to stop. Or the PCBA produced by the factory is unusable and needs to be reworked. The aforementioned problems will increase labor costs, rework costs, design cycles, and project production cycles.

[0071] In view of the discovery of the above problems, the present embodiment provides a method for adjusting the directional silk screen of PCB components, an electronic device and a storage medium. The method can obtain the package names and bit numbers of all components on the PCB board, determine the information table of all components on the PCB board based on each package name and the corresponding bit number, determine whether the package name has a welding direction requirement for each package name in the information table, when the package name has a welding direction requirement, determine at least one bit number corresponding to the package name, determine the indicator pin number corresponding to the package name, determine the position of the component in the PCB based on each bit number, determine the position of the direction indicator pin of the component according to the position and the indicator pin number, generate a predetermined query area based on the direction indicator pin position, and when there is a component directional silk screen in the predetermined query area, determine whether there is an interference risk in the component directional silk screen, and when there is an interference risk in the component directional silk screen, adjust the component directional silk screen. It can automatically traverse the components on the PCB board, and determine whether the components have directional silk screen, and automatically determine whether the directional silk screen has an interference risk based on an established method, and automatically adjust the directional silk screen when there is an interference risk of the directional silk screen, without the need for manual intervention, thereby improving the efficiency of adjusting the directional silk screen. The solution provided in this embodiment is described in detail below.

[0072] This embodiment provides an electronic device that can adjust the direction of silk screen printing of PCB components. In a possible implementation, the electronic device can be a user terminal, for example, the electronic device can be, but is not limited to, a server, a smart phone, a PC (Personal Computer), a tablet computer, a PDA (Personal Digital Assistant), a MID (Mobile Internet Device), etc.

[0073] Please refer to Figure 1 , Figure 1 1 is a schematic diagram of the structure of the electronic device 100 provided in the embodiment of the present application. The electronic device 100 may also include Figure 1More or fewer components as shown, or with Figure 1 Different configurations shown. Figure 1 Each component shown in the figure can be implemented by hardware, software or a combination thereof.

[0074] The electronic device 100 includes a PCB component direction screen printing device 110 , a memory 120 and a processor 130 .

[0075] The software for adjusting the silk screen direction of PCB components is installed in the electronic device, and the PCB board and the electronic device interact through the setting ports of the PCB board and the electronic device, so that the electronic device can obtain the information of each component from the PCB board for adjusting the silk screen direction of the PCB components.

[0076] The components of the memory 120 and the processor 130 are electrically connected to each other directly or indirectly to realize data transmission or interaction. For example, these components can be electrically connected to each other through one or more communication buses or signal lines. The device 110 for adjusting the direction of silk screen printing of PCB components includes at least one software function module that can be stored in the memory 120 in the form of software or firmware or solidified in the OS (operating system) of the electronic device 100. The processor 130 is used to execute the executable modules stored in the memory 120, such as the software function modules and computer programs included in the device 110 for adjusting the direction of silk screen printing of PCB components.

[0078] Please refer to Figure 2 , Figure 2 For application Figure 1 A flowchart of a method for adjusting the direction of silk screen printing of a PCB component of an electronic device 100 is provided, and the method including each step is described in detail below.

[0079] S201: Obtain the package names and position numbers of all components in the PCB board.

[0080] S202: Based on each package name and corresponding bit number, determine the information table of all components in the PCB board.

[0081] S203: For each package name in the information table, determine whether the package name has a welding direction requirement.

[0082] S204: When the package name has a welding direction requirement, determine at least one bit number corresponding to the package name.

[0083] S205: Determine the package name corresponding to the indicated pin number.

[0084] S206: Based on each bit number, determine the position of the component in the PCB.

[0085] S207: Determine the direction indicator pin position of the component according to the position and the indicator pin number.

[0086] S208: Generate a predetermined query area based on the position of the direction indication pin.

[0087] S209: When there is a component direction silk screen in the predetermined query area, determine whether there is an interference risk in the component direction silk screen.

[0088] S210: When there is a risk of interference in the silk screen printing direction of components, adjust the silk screen printing direction of components.

[0089] Traverse all components on the PCB board and grab the package name and bit number of each component. There are many ways to implement the information table of all components on the PCB board based on each package name and corresponding bit number. In one implementation, Figure 3 As shown, the following steps are included:

[0090] S202-1: Query a predetermined information table for each package name.

[0091] The established information table includes the correspondence between each package name and bit number.

[0092] S202-2: When the bit number corresponding to the package name is found in the established information table, it is added to the bit number queue of the package name to form an information table.

[0093] S202-3: When the bit number corresponding to the package name is not found in the established information table, the package name and the corresponding bit number are added to the established information table to form an information table.

[0094] In one example, before storing with "package name" as the keyword and "bit number" as the data unit, it is necessary to first determine whether there is a queue with the current "package name" as the keyword in the established information table. If not, create a queue with the current "package name" as the keyword, and then store the bit number corresponding to the current package name in the queue corresponding to the package name to form an information table. If it exists, locate the queue with the same "package name" keyword in the established information table, and store the "bit number" corresponding to the current package name in the queue in an appended manner to form an information table.

[0095] In another example, before storing the data unit with the "package name" as the keyword and the hash value of the "bit number", it is necessary to first determine whether there is a queue with the current "package name" as the keyword in the established information table. If it does not exist, create a queue with the current "package name" as the keyword, and then store the hash value corresponding to the bit number corresponding to the current package name in the queue corresponding to the package name to form a hash table. If it exists, locate the queue with the same "package name" keyword in the established information table, and store the hash value corresponding to the "bit number" corresponding to the current package name in the queue in an appended manner to form a hash table.

[0096] The package names of all components in the PCB board are traversed, and it is determined whether there is a welding direction requirement for the package name, and the indicator pin position is determined based on the bit number corresponding to the package name, and a predetermined query area is generated based on the indicator pin position. When there is a component direction silk screen in the predetermined query area, it is determined by a predetermined method whether there is an interference risk in the component direction silk screen. When there is an interference risk, the component direction silk screen is adjusted by the established method to eliminate the interference risk.

[0097] In one example, the current package name is determined, and it is determined that the current package name has a welding direction requirement, the A position number corresponding to the current package name is determined, the indicator pin number corresponding to the current package name is determined, and the position of the component with the A position number in the PCB is determined. According to the position of the component with the A position number in the PCB board and the indicator pin number, the direction indicator pin position of the component is determined, and based on the direction indicator pin position, a predetermined query area is generated. When there is a component direction silk screen in the predetermined query area and there is a risk of interference in the component direction silk screen, the component direction silk screen is adjusted.

[0098] In another instance, when the current package name corresponds to multiple bit numbers, the position of the component of each bit number in the PCB board is determined for each bit number, and based on the position of the component and the indicator pin number of each bit number in the PCB board, multiple directional indicator pin positions of the component are determined, and based on the multiple directional indicator pin positions, multiple established query areas are generated. For each established query area, it is determined whether there is a directional silk screen of the component. When there is a directional silk screen of the component in the established query area, it is determined whether there is an interference risk for the directional silk screen of the component in the established query area, and each directional silk screen of the component with an interference risk is adjusted.

[0099] When there is no component orientation silk screen in a given query area, a new component orientation silk screen is set in the given query area.

[0100] For each package name in the information table, there are multiple ways to determine whether the package name has a welding direction requirement. In one implementation, for example Figure 4 As shown, the following steps are included:

[0101] S203-1: For each package name in the information table, query a predetermined database.

[0102] The established database includes the corresponding relationship between each first preset package name and component information.

[0103] S203-2: Determine component information corresponding to the package name from a predetermined database.

[0104] S203-3: Determine from the component information whether the package name has any soldering direction requirements.

[0105] Traverse each package name in the information table, that is, for each queue in the information table, grab the queue keyword, that is, the package name.

[0106] Compare the currently captured package name with the package names stored in the established database one by one. When there is a package name in the established database that is consistent with the currently captured package name, obtain the field value of whether there is a welding direction requirement corresponding to the matched package name, return the field value as the parsing result, and terminate this round of comparison and capture queue keywords. When the package name corresponding to the current package name is not matched in the established database, the next package name in the information table is captured until all package names in the information table are traversed.

[0107] It should be noted that the above-mentioned established database is a component management library. The library stores all component information. The component information includes the corresponding relationship between the package name, whether there is a welding direction requirement, the welding direction indication pin number and other information.

[0108] There are many ways to determine the package name corresponding to the indicated pin number. In one implementation, for example Figure 5 As shown, the following steps are included:

[0109] S205-1: Query a predetermined database for the package name.

[0110] S205-2: Determine component information corresponding to the package name from a predetermined database.

[0111] S205-3: Determine the indicated pin number corresponding to the package name from the component information.

[0112] Since the established data contains the correspondence between the package name and the pin number indicating the welding direction, the currently captured package name is compared one by one with each package name stored in the established database. When there is a package name corresponding to the currently captured package name in the established database, the indicating pin number in the component information of the matching package name is determined.

[0113] When there is a component orientation screen in a given query area, there are multiple ways to determine whether there is an interference risk in the component orientation screen. In one implementation, for example Figure 6 As shown, the following steps are included:

[0114] S209-1: When there is a component direction silk screen in the established query area, determine whether there is another direction silk screen in the established query area.

[0115] S209-2: When there are other directional silk screens in the predetermined query area, determine a first distance between the component directional silk screen and the other directional silk screens.

[0116] S209-3: When the first distance is less than the preset distance, it is determined that there is a risk of interference in the silk screen printing of the component direction.

[0117] When a predetermined query area is generated based on the direction indicator pin position, a circular area with a center coordinate point of the direction indicator pin position as a circle point and a preset distance as a radius is used as the predetermined query area.

[0118] It should be noted that the preset distance can be set to 1mm, 1.5mm, 2mm, etc., and the embodiment of the present application does not impose any specific limitation on this.

[0119] Search whether there is a specific parameter feature in the established query area, the specific parameter feature is used to indicate the direction silk screen of the component. When the specific parameter feature exists in the established query area, it is determined that there is a direction silk screen of the component in the established query area. When the specific parameter feature does not exist in the established query area, it is determined that there is no direction silk screen of the component in the established query area.

[0120] When there is a component directional silk screen in a given query area, query whether the given query area contains other directional silk screens. When other directional silk screens are contained in the given query area, the component directional silk screen and the other silk screens may interfere with each other, thereby affecting the performance of the final PCB board. It is necessary to determine the first distance between the component directional silk screen and the other silk screens, and determine whether there is an interference risk for the component directional silk screen based on the first distance.

[0121] As for the method of determining the first distance, the distance between the center point of the silk screen in the direction of the component and the center point of other silk screens can be used as the first distance. By comparing the first distance with the preset distance, when the first distance is less than the preset distance, it is determined that there is an interference risk in the silk screen in the direction of the component, and the silk screen in the direction of the component needs to be adjusted.

[0122] Another way to determine whether there is an interference risk for the component directional silk screen is as follows: when there is a component directional silk screen in a given query area, determine the pads in the given query area, determine a second distance between the component directional silk screen and the pads, and when the second distance is less than a preset distance, determine that there is an interference risk for the component directional silk screen.

[0123] Determine whether there is a solder pad in a given query area. When there is a solder pad in the given query area, the vertical distance between the center of the component directional silk screen and the solder pad can be used as the second distance, and the second distance can be compared with the preset distance. When the second distance is less than the preset distance, it is determined that there is an interference risk in the component directional silk screen; when the second distance is greater than or equal to the preset distance, it is determined that there is no interference risk in the component directional silk screen.

[0124] When there is a risk of interference in the direction of the silk screen printing of components, there are many ways to adjust the direction of the silk screen printing of components. In one implementation method, Figure 7 As shown, the following steps are included:

[0125] S210-1: When there is a risk of interference in the silk screen printing of the component direction, move the silk screen printing of the component direction.

[0126] S210-2: Determine whether there is a risk of interference in the silk screen printing direction of the moved components.

[0127] S210-3: When there is a risk of interference in the direction of the silk screen of the moved component, change the shape of the silk screen in the direction of the component.

[0128] S210-4: Determine whether there is a risk of interference in the silk screen direction of the component after the shape is changed.

[0129] S210-5: When there is a risk of interference in the silk screen printing direction of the component after the shape is changed, reduce the radius of the silk screen printing direction of the component after the shape is changed.

[0130] Exemplarily, when there is a risk of interference in the silk screen printing in the direction of components, adjustment is performed by at least one of moving the silk screen printing in the direction of components, changing the shape of the silk screen printing in the direction of components, and reducing the radius of the silk screen printing in the direction of components.

[0131] When there is a risk of interference in the component direction silk screen, it can be adjusted by moving the component direction silk screen, changing the shape of the component direction silk screen, or reducing the radius of the component direction silk screen.

[0132] In another example, the adjustment can be made in the order of moving the component directional silk screen, changing the shape of the component directional silk screen, and reducing the radius of the component directional silk screen. For example: when there is a risk of interference in the component directional silk screen, the shape of the component directional silk screen can be changed first to determine whether there is an interference risk in the component directional silk screen after the shape change. If there is no interference risk, the next package name in the information table is obtained for judgment. When there is an interference risk, the component directional silk screen after the shape change is moved, and it is determined again whether there is an interference risk in the component directional silk screen after the movement. If there is an interference risk, the radius of the component directional silk screen after the movement is reduced to avoid the interference risk of the component directional silk screen.

[0133] In another example, when there is a risk of interference in the component directional silk screen, the component directional silk screen can be moved first to determine whether there is still a risk of interference. When there is a risk of interference in the component directional silk screen after the move, the shape of the original component directional silk screen is changed to determine whether there is still a risk of interference. If there is still a risk of interference after changing the shape of the original component directional silk screen, the radius of the original component directional silk screen is reduced to reduce the component directional silk screen and determine whether there is still a risk of interference. If not, the next package name in the information table is obtained for judgment.

[0134] It should be noted that the embodiment of the present application does not impose any specific restrictions on the method of adjusting the silk screen of the component direction. It can be a combination of moving the silk screen of the component direction, changing the shape of the silk screen of the component direction, or reducing the radius of the silk screen of the component direction, as well as specifying the execution order of moving the silk screen of the component direction, changing the shape of the silk screen of the component direction, or reducing the radius of the silk screen of the component direction.

[0135] There are many ways to process the redundant silk screen in the PCB board. In one implementation, Figure 8 As shown, the following steps are included:

[0136] S301: The first ID information of the direction silk screen of each component in each predetermined query area is stored in the component direction silk screen table.

[0137] S302: Traverse all silk screens on the PCB board to determine whether the silk screen is a directional silk screen.

[0138] S303: When the silk screen printing is directional silk screen printing, determine the second ID information of the silk screen printing.

[0139] S304: Match the silk-screened second ID information with each first ID information in the component direction silk-screen table.

[0140] S305: When there is no first ID information consistent with the second ID information in the component direction silk screen table, the silk screen is deleted.

[0141] Determine whether there is a component direction silk screen in the established query area. If not, set a new component direction silk screen in the established query area, determine the first ID information of the new component direction silk screen, and store it in the component direction silk screen table. If there is a component direction silk screen in the established query area, determine the first ID information of the component direction silk screen and store it in the component direction silk screen table. Get all silk screens on the PCB board, determine all direction silk screens in each silk screen, and determine the second ID information of each direction silk screen. For each second ID information, match the second ID information with each first ID information in the component direction silk screen table. If the first ID information corresponding to the current second ID information does not exist in the component direction silk screen table, the current second ID information is considered to be redundant with the device direction silk screen, and the current direction silk screen is deleted. Avoid redundant component direction silk screens from misleading subsequent PCB processing operations.
