Hello Everyone,
        A question has been brought to me.  What is the smallest soldermask
relief to a surface mount pad being used in today's world.  I'm being told
that a 5 mil relief is a good safe number, however, with parts that are 10
mil pitch that a 3 mil or less should be used.  What have some of you run
into?
