Hi ya'll!

Most all my reflow profiling experience has been with the typical Sn63Pb37 
alloys. But we'll be getting some products in here later on that will require 
that we use a SN96AG04 alloy (they're boards that go into oil well drill head 
instumentation, hot stuff down there!) Liquidous will be up around 221-229º 
C. 

So should I follow the same rules of thumb when it comes creating a profile 
for this stuff...ya' know; don't ramp more than 2-4º C per second, pre-heat 
and soak above 150º C for around a minute and a half, then spike it until 
you're 20-30º above liquidous, and try to be less than a minute while you're 
above liquidous? Or is there some special stuff I should do differently with 
this higher melting point temperature alloy?

'preciate it!
