The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] During the production and rework of PCBs (printed circuit boards), it is often necessary to locate specific components quickly and accurately.

[0023] Traditional positioning methods usually rely on manual search, that is, searching by comparing one by one on the PCB board or referring to drawings. However, with the increasing complexity and integration of modern electronic products, the number of components on the PCB board is increasing, and the spacing between components is getting smaller and smaller, which makes manual search particularly difficult. A new technical means is needed to solve the above technical problems.

[0024] In view of this, an embodiment of the present invention provides a method, apparatus, terminal device and storage medium for generating a PCB rendering, which can reduce the time required for manual component search by automatically generating a second PCB rendering.

[0025] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0026] Figure 1 The present invention provides a schematic diagram of a method for generating a PCB rendering provided by an embodiment of the present invention, which can be applied to a terminal device. The terminal device can be a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, etc.

[0027] Specifically, the above-mentioned method for generating a PCB rendering may include the following steps S101 to S103.

[0028] Step S101, when a manufacturing order number is detected, a first PCB rendering is displayed according to the manufacturing order number, and a component actual position data file is obtained according to the manufacturing order number.

[0029] In an embodiment of the present invention, the PCB rendering generation device detects whether a manufacturing order number is input, which can be received through a user interface (UI), such as scanning a QR code, manually inputting, or automatically importing from an ERP (Enterprise Resource Planning) system.

[0030] A valid manufacturing order number is detected and the corresponding Gerber file is retrieved from the database based on the order number. Gerber file is a standard file format in the PCB design industry, used to describe the layout, shape, copper layer and other information of the circuit board. Parse the Gerber file and display the overall PCB rendering.

[0031] At the same time, the actual position data file of the components related to the circuit board is obtained according to the manufacturing order number. The actual position data file of the components contains the precise position information of each component on the circuit board.

[0032] Step S102, when human-computer interaction information interacting with the first PCB rendering is detected, positioning data is generated according to the human-computer interaction information, and the positioning data includes the position numbers of the three target components and the coordinates of the three target components in the first PCB rendering.

[0033] In an embodiment of the present invention, interactive operations on the user interface, such as mouse clicks, drags, keyboard inputs, etc., are monitored.

[0034] When it is detected that the user interacts with the displayed first PCB rendering, the user's operation intention is identified, such as selecting a specific component, and it is verified whether the number of components selected by the user meets the requirements (three target components in this example).

[0035] According to the three target components selected by the user, the position numbers (component identification) of these components are extracted from the first PCB rendering. At the same time, the system records the pixel coordinates of these components in the first PCB rendering. The position numbers and pixel coordinates are combined into positioning data.

[0036] Optionally, it is indicated that three image areas corresponding to three target components are selected in the first PCB rendering to form human-computer interaction information. The first PCB rendering is displayed through a user interface, and the image contains multiple layers of information, such as a top layer, a bottom layer, a circuit layer, etc. The user can view the details of the image through functions such as zooming and panning on the interface. After detecting the user's interactive operations, these operations are converted into human-computer interaction information. The human-computer interaction information includes the image area coordinates of the three target components selected by the user, the order of selection, etc. According to the human-computer interaction information, positioning data including the bit numbers of the three target components and their coordinates in the first PCB rendering is generated. The bit number is a unique identifier of the component, and the coordinates describe the position of the component in the image. By allowing the user to directly select the target component in the first PCB rendering, the time for manual input and verification is reduced, and the overall work efficiency is improved.

[0037] Step S103, generating a coordinate system parameter according to the positioning data and the component actual position data file.

[0038] In an embodiment of the present invention, the positioning data and the component actual position data file are used to generate a coordinate system parameter. This parameter is used to unify the coordinate system in the first PCB rendering and the coordinate system in the component actual position data file.

[0039] It should be noted that, through the coordinate system one parameter, the coordinates in the component actual position data file can be converted to the same coordinate system as the first PCB rendering image for subsequent processing.

[0040] Step S104, generating a second PCB rendering according to the coordinate system first parameter and the component actual position data file.

[0041] In an embodiment of the present invention, a second PCB rendering is generated based on the coordinate system parameters and the component actual position data file. This rendering shows the actual position and layout of all components on the PCB, which can be used for inspection, error detection or confirmation before and after production.

[0042] Compared with the prior art, the embodiments of the present invention have the following beneficial effects: when a manufacturing order number is detected, a first PCB rendering is displayed according to the manufacturing order number, and a component actual position data file is obtained according to the manufacturing order number; when human-computer interaction information interacting with the first PCB rendering is detected, positioning data is generated according to the human-computer interaction information, and the positioning data includes the position numbers of three target components and the coordinates of the three target components in the first PCB rendering; a coordinate system parameter is generated according to the positioning data and the component actual position data file; a second PCB rendering is generated according to the coordinate system parameter and the component actual position data file. By automatically generating the second PCB rendering, the time required for manual component search can be reduced.

[0043] Figure 2 1 is a schematic diagram of a specific embodiment of step S101 of the method for generating a PCB rendering in an embodiment of the present invention. Step S101 also includes the following specific implementation methods.

[0044] Step S1011, displaying the overall PCB rendering according to the Gerber file corresponding to the manufacturing order number.

[0045] In an embodiment of the present invention, an image rendering technique is used to convert a Gerber file into an image that can be displayed on a user interface, for example, information such as circuits, pads, solder resists, etc. in a Gerber file is parsed and presented to a user in a graphical manner.

[0046] After displaying the overall PCB rendering, detect whether the user has issued a face selection command based on the interactive interface. Faces usually refer to different layers of the PCB, such as the top layer, bottom layer, circuit layer, solder mask layer, etc. Users can select specific faces through buttons, drop-down menus or other interactive elements on the user interface.

[0047] Step S1012, when a selection instruction for a plane is detected, the overall PCB rendering is switched to a first PCB rendering corresponding to the plane according to the Gerber file.

[0048] In an embodiment of the present invention, a valid face selection instruction is detected, corresponding face information is extracted from the Gerber file according to the user's selection, and the image displayed on the user interface is updated, so that the user can view different levels of the PCB.

[0049] In the embodiment of the present invention, the user can view and analyze different layers of the PCB, which helps the user to better understand the layout and circuit information of the PCB, thereby speeding up the error correction speed of the second PCB rendering generated subsequently.

[0050] In the field of PCB design and manufacturing, the first PCB rendering and the component actual position data file are two important data sources. The first PCB rendering is usually used to describe the layout and circuit information of the PCB, while the component actual position data file contains the actual position information of all components on the PCB. However, since these two data sources may use different coordinate systems, it is difficult to combine them. Based on this, the present invention proposes an optional embodiment.

[0051] Figure 3 1 is a schematic diagram of a specific embodiment of step S103 of the method for generating a PCB rendering in an embodiment of the present invention. Step S103 also includes the following specific implementation methods.

[0052] Step S1031, determining the actual coordinates corresponding to the three target components in the component actual position data file according to the bit numbers in the positioning data.

[0053] In an embodiment of the present invention, after the human-computer interaction information is detected and the positioning data is generated, the positioning data is parsed. The positioning data includes the position numbers of the three target components and their coordinates in the first PCB rendering.

[0054] According to the bit number in the positioning data, the actual coordinates of the corresponding target components are retrieved in the component actual position data file. The component actual position data file is a database or file containing the actual positions of all components on the PCB.

[0055] The coordinates (pixel coordinates) in the first PCB rendering obtained by analysis are aligned with the actual coordinates (physical coordinates) in the component actual position data file. This step can achieve the conversion and unification of the coordinate system so that the two can be compared and calculated under the same coordinate system.

[0056] Step S1032, generating a coordinate system parameter according to the actual coordinates and the coordinates in the positioning data.

[0057] In an embodiment of the present invention, a coordinate system parameter 1 is generated according to the result of the benchmarking operation. The coordinate system parameter 1 is used to unify the coordinates in the component actual position data file into the same coordinate system as the first PCB rendering in subsequent steps, so as to generate a second PCB rendering.

[0058] In the embodiment of the present invention, through the coordinate alignment operation, the coordinates in the first PCB rendering and the coordinates in the component actual position data file can be in the same coordinate system, thereby improving the accuracy of the generated second PCB rendering.

[0059] Optionally, step S1032 further includes: Step S10321, performing a calibration operation between the actual distance and the pixel distance according to the actual coordinates and the coordinates in the positioning data, and obtaining a coordinate system parameter.

[0060] In an embodiment of the present invention, the proportional relationship between the pixel coordinates and the actual coordinates is determined according to the resolution and size of the first PCB rendering. The pixel coordinates are converted to the actual coordinates, or the actual coordinates are converted to the pixel coordinates, to ensure that the two are consistent in the same coordinate system.

[0061] According to the result of the benchmarking operation, a coordinate system parameter 1 is generated. The coordinate system parameter 1 includes a scale factor, an offset, etc., which is used to unify the coordinates in the component actual position data file into the same coordinate system as the first PCB rendering in the subsequent steps.

[0062] By performing a calibration operation between the actual distance and the pixel distance, the coordinates in the first PCB rendering and the coordinates in the component actual position data file can be made consistent in the same coordinate system, thereby improving the accuracy of the generated second PCB rendering.

[0063] Step S103 also includes the following specific implementation methods.

[0064] Step S1033, performing a coordinate unification operation on the component actual position data file according to a parameter of the coordinate system, to obtain the target component actual position data file.

[0065] In an embodiment of the present invention, all coordinates in the component actual position data file are converted using a coordinate system parameter.

[0066] After the coordinate unification operation is completed, a new data file is generated, namely the actual position data file of the target component. All coordinates in this file have used the coordinate system corresponding to the first PCB rendering.

[0067] Step S1034, generating a second PCB rendering according to the target component actual position data file.

[0068] In the embodiment of the present invention, through the coordinate unification operation, the actual position of the component and the position in the first PCB rendering are consistent in the coordinate system, thereby improving the accuracy of the rendering.

[0069] There are many factors in the PCB manufacturing process that may cause the actual position of the component to be inconsistent with the position in the first PCB rendering. For example, machine errors, data input errors, component placement errors, etc. may all cause this problem. Traditional inspection methods usually rely on manual review or simple automated inspection tools, which are often inefficient and prone to missing problems. Based on this, the present invention proposes an optional embodiment.

[0070] The following specific implementation is also included after step S104.

[0071] Step S201, judging whether there is abnormal coordinate data in the actual position data file of the target component according to the Gerber file corresponding to the manufacturing order number.

[0072] In an embodiment of the present invention, after performing a coordinate unification operation on the component actual position data file according to a coordinate system parameter, it is checked whether each coordinate data in the target component actual position data file matches the expected position in the first PCB rendering.

[0073] Step S202: If there is abnormal coordinate data, the abnormal area corresponding to the abnormal coordinate data is highlighted in the second PCB rendering.

[0074] In an embodiment of the present invention, if the system detects that there are abnormal coordinate data in the actual position data file of the target component, that is, the actual position of one or some components is inconsistent with the expected position in the first PCB rendering, these abnormal areas will be highlighted in the second PCB rendering.

[0075] Specifically, highlighting can be achieved by changing the color, border, or other visual attributes of the abnormal area so that users can easily identify potential problems.

[0076] In the embodiment of the present invention, by detecting and highlighting the area corresponding to the abnormal coordinate data, it is possible to help the user find potential errors in time, thereby improving the repair efficiency.
