I've made a test to check violations on a test PCB. I am getting DFM violations, but only to a max of 50 violations.
When I run this same DFM check in FAB3000, I get 4000+ violations. Is it possible to change the maximum of DFM violations displayed/detected in preflight?
Yes you're correct, by default FAB 3000 purposely limits DFM violation count to 50 (per specific DFM Rule) and a total of 500 DFM violations reported - instead of permitting unlimited violations (like 4000+ DFM reported errors).
There are two reasons for this limit:
- Information Overkill: Usually reporting every DFM violation (like 4000+ violations) gets to the point of information overkill for the customer (like Google search returning 200k results - when typically the first few page results are adequate).
- Bigger reports and slower performance: Continuing to perform DFM analysis until every violation is detected requires more time and resources with bigger DFM Violation reports.
To increase the number of Violations permitted upwards, please assign the Max per Rule and Max Total variables (see below).
