Mr. Brucker,

     I'd attach your TechNet reply, but errantly zapped it this morning
     while scanning the Net.  I did read it though, and you bring up good
     points about inspection criteria.  We routinely perform a physical
     destructive analysis (DPA) of production boards, and I have cross
     sectioned many of these joints. My own experience is that they've been
     troublefree, and certainly achieve compliant heel and side fillets.
     Toe fillets are not a requirement for gullwing leads because the
     common presence of exposed copper from the shearing process, and
     occasionally the permissible toe overhang, can make those fillets very
     difficult to achieve. I see a request on the Net for info on palladium
     finished boards; I've not run into them yet. That could be a blessing.
