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. DFM Checks are performed instantly & securely right on your computer. There are currently over 30,000 registered users of DFM Now! spanning across the globe from: United States, Germany, England, Italy, South Africa, Australia, India, Japan, China, and more.

Do I need internet access to run DFM Now?

No. DFM Now! 6.6 and above no longer requires internet access and will run perfectly fine on any computer -- whether connected to the internet or not.

Can I still use the previous version of DFM Now?

Unfortunately no. The previous version of DFM Now! was "advertising sponsored". The new DFM Now! no longer shows ads and will benefit many corporate/government users who were unable to run DFM Now! in the past due to Internet/Proxy restrictions.

Can I export data from DFM Now? How do I get advanced features like Netlist Compare, Merge/Panelize PCB's, Build Centroids, etc?

To export data or for more advanced features, you will need to upgrade to our popular CAM tool FAB 3000 (see below for a feature comparison).
