Many friends will encounter the situation of graphic misalignment when using wonderfulpcb DFM Services software to import Gerber files. The reason for the misalignment of graphics is that there are unknown objects outside the design file frame, and the canvas size of each layer is different, which causes the coordinates to change with the canvas size when the EDA software converts the Gerber file, resulting in graphic offset. So how to align the graphics of the Gerber file? The following wonderfulpcb DFM Services takes you to fly!
Board layer graphic alignment
1. Single layer alignment
The first step is to close other layers and only display the layer to be moved and the reference alignment layer. Double-click the layer to close other layers, display only one layer, and then click to open another layer.
The second step is to open the grab center, that is, to grab the center of the graphic object. You can open the grab center in the lower right corner, or you can set the grab center in the menu bar, Settings-Object Paving.
The third step is to find the common point of alignment. The layer with a check mark is the operation layer, and the moving layer is the operation layer. Grab the center of the common point of the moving layer, press the Ctrl+D shortcut key, click the common point of the moving layer, and move it to the position of the common point of the alignment layer.
Align the graphics.
2. Local graphics alignment
Local graphics alignment is the same as single-layer alignment. The premise is to first select the local object to be aligned, then press the Ctrl+D shortcut key, click the common point of the moving layer, and place it on the common point of the alignment layer to align locally.
3. Multi-layer alignment
The general application scenario of multi-layer alignment is to compare the differences between file A and file B after the design file is revised.
When the imported second file is not aligned with the first file, alignment is required.
The alignment operation is similar to single-layer alignment. First close other layers and open the layer to be aligned. Open one layer of file A and one layer of file B. The file to be moved needs to open the influence layer of other layers.
Press the Ctrl+D shortcut key again, click the common point of the moving layer, and place it on the reference point of the alignment layer to align all layer files.
Coordinate file graphic alignment
When using Gerber files for assembly analysis, if the coordinates are not aligned with the board graphics, perform alignment operations.
- Select a component.
- Select the pad. Select the PCB package corresponding to the component. If the package has multiple pads, hold down the Ctrl key and use the mouse to select continuously to select all PCB package pads.
- Click the alignment button to align the file. If the bottom layer coordinates need to be aligned synchronously, select Synchronous movement of the bottom layer. If the bottom layer does not need to be synchronized, there is no need to check the synchronous movement alignment.
Component library graphic alignment
When using assembly analysis to match the component library, if the component library and the PCB package pads are not aligned, the component library can be moved to align.
- You can choose to display the graphics of the PCB file for easy viewing and alignment, displaying circuits, solder mask, silk screen, and drilling.
- The component library can be rotated at a 45-degree angle.
- The middle of the 4 arrows is the step distance of movement, which can be adjusted up or down.
- Click the arrows up, down, left, and right to move in four directions.
In the past, when using wonderfulpcb DFM Services software, the alignment of graphic layers was not very convenient, and some users even did not know how to use it, which made it impossible to work. Therefore, wonderfulpcb DFM Services software has optimized the graphic alignment function, hoping to provide users with a better experience.
