Looking for some up front info on using flash symbols before I dive into it. I have never used these before and am interested in seeing flashes in wysywyg mode. Can flash symbols only be used in padstacks on internal layers? As thermals? or can they be used on external layers such as top and bottom pads, soldermask and solder paste. We have a funky solderpaste stensil that requires multiple separated shapes that cannot be generated with one continuous shape which is needed for an ssm. Also is there any online documentation that explains the best way to use flash symbols? Like a Flash Symbol Users Guide? thanks, Mike Gnieski EMC2 Corp. Hopkinton, MA
