Frequently Asked Questions

 Why do you do offer DFM Now! Free?

DFM Now! is provided at no cost to give hobbyist and small PCB designers the ability to verify their PCB design data is good before sending out to manufacturing. There are over 30,000 DFM Now! users worldwide from: United States, Germany, England, Italy, South Africa, Australia, India, Japan, China, and more.

Do I have to upload my CAM files (i.e. Gerber/Drill/ODB++) to some website and wait for a response?
No. You do not need to upload your design files to some website and wait for their response.  DFM Checks are performed instantly & securely right on your computer.
Does DFM Now! perform a full-featured DFM and Netlist Check for free?
Yes.  DFM Now! will freely perform a full-featured DFM and Netlist Check typically found on software tools costing thousands of dollars - it is not a limited check.  If your design has passed, DFM Now! will let you know by displaying a "Success Icon"  -- which means your design is now ready for manufacturing. 
What happens if my Design contains violations?
If your design contains any violations DFM Now! will display a color-coded  summary which specifies the type of violations and the total counts of each.  This summary gives all DFM Now! users a good idea of problems in their design, and an opportunity to go back to repair them in their layout tools. 
Will DFM Now! pinpoint DFM and Netlist violations if they are detected?
No. DFM Now! will not pinpoint violations that are detected. If you would like to know coordinate locations of each violation, Net names for all Shorts & Opens, the ability to interactively browse each violation (with dynamic zoom-in), generate detailed reports (with pictures), and more - would require our popular CAM tool FAB 3000

Can I Save and Export files from DFM Now? 

No. To save and export files (such as Gerber, Drill, ODB++, DXF, etc.), would require our popular CAM tool FAB 3000
