Hi all, I'm looking for ideas on interpreting the data I've taken on my EMScan. For anyone not familier with EMScan, it maps the currents flowing on a PWB using 3 dimensional loops under a 5 mm square grid.
I have taken a number of charts at different frequencies that show banding across the longest side of the board. At first glance it would ook like I'm seeing the board resonate, but I can't be sure. Anyone interested in proffering opinions as to what could be going on? I'm assembling the charts into an acrobat file that I can mail on request. I didn't want to flood the list with an attachment that could be almost a MB. Thanks in advance. Derek N. Walton Owner, L. F.
