Karl,
We see between 10 and 30 new designs a week come in and I estimate that
30 to 40% of those do not have thermal relief on the via sizes. This
design is being used by my customers and I have not hear any negative
feed back.
I have not seen this used on technologies using more than 2 power and
ground planes, although I don't know why it would not apply there also.
