Hey guys, 

I just realized. What we are paying are called taxes BUT - it's probably
a royalty fee, as the IRS must have the patent on air-breathing money
earning bipeds, it's just that no one has challenged the patent yet..

Very  interesting.

Does that mean that patent cover the solder mask open  window and trace
width?. If you simply change nothing on your design, but  open up a slot
in the solder mask on the trace side of the pad you will get  a
"keyhole"
effect in the final soldered joint  automatically.

Hi John,

Thinking like a lawyer are you?... RoHS is having that effect on a lot
of
good engineers lately... ;-)

Actually I would argue that you are probably right but would need to
make
certain by reading the claims which could as a counter point might  have
a claim
to equivalence, something which could possibly be construed  from a well
crafted claim. Therein lies the art...

Best,
Joe
