[0002] In the production of low-density PCB (circuit board) samples, manual soldering is often used to produce a small number of PCBAs (PCBs after SMT) because of time cost and flexibility. When there are few devices, generally less than 100, skilled workers can be asked to solder directly. The most time-consuming and error-prone workflow for manual soldering is to find the location of the corresponding material on the BOM. Because SMT materials are relatively small, the material model cannot be distinguished from the appearance. Generally, PCBs with higher density will not be placed on the PCB with silk screen, so it is necessary to compare and query multiple documents to confirm the material. When the material is greater than 100 and less than 1,000, if the SMT cycle is long, manual direct soldering is difficult to quickly and accurately locate the components because the PCB has no silk screen, and soldering is prone to errors.

[0068] It should be noted that, for the aforementioned method embodiments, for the sake of simplicity, they are all expressed as a series of action combinations, but those skilled in the art should be aware that the present application is not limited by the described order of actions, because according to the present application, certain steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily required by the present application.

[0069] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0071] The system for assisting PCBA welding includes: a file system unit 100, a positioning unit 200 and a display unit 300. The file system unit 100 is used to load silk screen, component coordinate files, BOM tables and PCB physical pictures; the positioning unit 200 traverses the component coordinate files according to the positions of the components clicked in the PCB physical pictures to determine the coordinates of the clicked components; finds the information of the corresponding components in the BOM table according to the coordinates of the components; obtains the silk screen position of the components according to the information of the components in the BOM table; the display unit 300 is used to display the loaded BOM table, PCB physical pictures and the silk screen position of the clicked components in the PCB physical pictures determined by the positioning unit 200.

[0072] Manual soldering has more advantages in terms of cycle and cost in PCBA sample development and small-batch trial production. The system for assisting PCBA soldering based on the present invention solves the problem that the PCB has no silk screen during manual soldering of PCBA samples and components are difficult to locate quickly and accurately. When the number of materials is greater than 100 and less than 1000, the soldering position of the materials can also be quickly and accurately located. Compared with SMT, the development speed of equipment is greatly accelerated and the cost is reduced.

[0073] Further, such as Figures 3 to 5 As shown, the PCB physical image displayed by the display unit 300 includes an enlarged image of the PCB physical image and a thumbnail of the PCB physical image. Based on the thumbnail of the PCB physical image, the approximate position of the clicked component in the enlarged image of the PCB physical image can be summarized, providing directional guidance for installing components during the PCBA assembly process. Combined with the enlarged image information of the PCB physical image, it assists the welding personnel to quickly locate (find) the welding position of the components.

[0074] Specifically, the silk screen is a DXF file, which records the text, numbers or symbols printed on the PCB to assist in identifying and installing components during the PCBA assembly process. The component coordinate file includes the coordinates of each component, and the position of the component on the silk screen can be found through the coordinates of the component. The BOM table includes the quantity, name, description and cost of materials, components and parts required to assemble the PCBA. The PCB physical picture is a real picture of the front side of a PCB or a real picture of the back side of a PCB.
