1) While importing FreePCB CAM files into circuit CAM
- If you find the package pads shorted out, then change the following settings
- Go as usual to Generate CAM files.
- In the window that pops up, set the Gerber file dimensions as follows
- Copper to copper fill clearance = 1
- Hole edge to copper-fill clearance = 1
- Leave the rest as it is.
- If you find the package pads shorted out, then change the following settings
2) When you import the FreePCB generated CAM files "drill" you will initially
- find that the drill holes occupy the entire screen and your actual board layout
- shrinks to a small size.
- Fix : Go to Config --> Format Configuration --> Excellon Tool list.
- There change the 3rd row 3rd column number from 3 to 4 by right clicking on that
- Change number 3 and then setting into 4 in the window that pops up.
