Mrph12 Posted March 20 Share Posted March 20 I Have been working for some time on detecting double-die Errors. Can someone help me determine which DDR this may be? Link to comment Share on other sites More sharing options...
Coinbuf Posted March 20 Share Posted March 20 (edited) Strike doubling not a DDR. Edited March 20 by Coinbuf Link to comment Share on other sites More sharing options...
Mike Meenderink Posted March 20 Share Posted March 20 I second that opinion. Strike doubling. Link to comment Share on other sites More sharing options...
Greenstang Posted March 20 Share Posted March 20 A Doubled Die is not an error, it is a variety. What you have is Machine Doubling, aka Strike Doubling, not a DD. Link to comment Share on other sites More sharing options...
