MNF is a Ucamco proprietary input format for electrical test equipment. Using MNF rather than IPC-356-A results in much higher troughput for the flying probe test. The reason is that MNF contains more information than the IPC-356-A, extra information that is needed for a flying probe tester to run at full speed.
Ucamco, Gardien, IGI and Mania have licenses to MNF and an official format description. All other products using MNF are unlicensed and developed without official format description, with the resulting integrity risks.
If you are interested in obtaining the MNF format description and a license to use its IP, including regularizing an established situation, please contact us at email@example.com or call us at +32 9 216 99 00
