PollEx DFM is rule-based PCB verification software for manufacturing engineers. Using PollEx PCB as its basis PollEx DFM supports PCB design data in various ECAD formats. It allows users to detect design errors which result in costly manufacturing defects.

Reduces Time and Cost of Design to Manufacturing Process

Its features allow users to reduce expense and loss of time occurring in a mass production cycle. Numerous manufacturing defect items are checked against the PCB design data, and any design errors are reported at the point of error so that they are easily identified and corrected. Consequently employing PollEx DFM results in significant reduction of manufacturing defects.
