In the process of electronic product development, scheme selection, schematic diagram design, BOM production, PCB design and then PCB and PCBA production will go through multiple version iterations. In the process of hardware development, the iteration of BOM files and the version iteration of PCB design are the most common, so the corresponding version control is very important. Only by clearly understanding the differences between different versions can we ensure the high quality of the final product after several iterations. Quality delivered.
Using an efficient and convenient comparison tool can get twice the result with half the effort, so after a month, Huaqiu DFM welcomes the release of a new version again in order to serve you better !
Combined with feedback from loyal users, and in order to have a more practical and convenient experience, the following functions have been optimized:
BOM comparison function
01
Interface optimization
The interactive interface is updated to a high-definition version, and the position of the import and export buttons is more obvious, and the user experience is smoother.
02
Function optimization
① Default sorting: The comparison results are displayed according to the original BOM line.
② Difference priority: The comparison results are displayed in priority according to the lines with differences.
③ Clear data: Check this button to close the BOM comparison tool and clear the data in the tool at the same time.
④ Comparison results: The lines with differences will be reported in red, and the specific positions of the differences will be displayed.
⑤ File header: When the header is not recognized correctly, the header can be adjusted.
⑥ Prompt for repeated bit number: After importing the file, click BOM comparison, and a pop-up window will prompt when there is a duplicate bit number.
⑦ Row and column data: Display the position of the row and column selected by the mouse.
⑧ Modify parameters: Select the position to be modified with the mouse, and click Modify to modify the parameters in the BOM file.
⑨ Tag details: When the tag is repeated, or the tag is missing, it will be displayed below.
PCB/Gerber file comparison
01
Interface optimization
Like the BOM comparison tool, it provides enhanced guidance on the interface of opening the comparison file, which is convenient for new users to import and export files. The supported file formats are: Allegro, PADS, Altium, Gerber, ODB files, etc.
02
Function optimization
① Comparison range: The position to be compared can be detected according to the entire range, within the profile, and a custom range.
② Contrast coefficient: The difference points can be compared according to the pixel size of the graphics.
③ Comparison data: Clear the comparison results and delete the _1 layer. When ticked, all layers in the comparison can be cleared.
④ Comparison layer selection: You can check the selective comparison of the layers that need to be compared.
⑤ Comparison and difference display: it can display all results, display differences, and give priority to differences.
⑥ View the comparison results: Click View to locate the position of the specific difference in the board.
⑦ Compare file operation: Click "Compare" to compare the differences, click "Close" to close the operation window and clear the data.
⑧ Single-layer comparison: select the original file, the comparison file layer, and select the layer to be compared.
⑨ Add comparison layer: Click the plus button to add a selection layer.
⑩ Delete the comparison layer: If you need to delete the comparison layer results separately, you can click the delete button to delete.
Adhering to the original intention of developing free and efficient software for the majority of hardware engineers, Huaqiu DFM has been working hard to optimize and develop useful functions, adding more usable scenarios, etc.
It is currently the first free PCB manufacturability and PCBA assembly analysis software in China, with a library of 3 million+ components, which can easily and efficiently complete assembly analysis. For the analysis function of PCB bare board, 19 major items and 52 detailed inspection rules have been developed. For the analysis function of PCBA assembly, 10 major items and 234 detailed inspection rules have been developed.
It can basically cover all possible manufacturability problems, can help design engineers check manufacturability problems before production, and can meet various scenarios required by engineers, minimize the number of iterations of product development, and reduce costs.
