Eric,

My two cents . . .

The lazy part of me wants to just make the change, but the engineer (anal
retentive?) part of me re-profiles the board.

I save all profiles on the computer so when I get the occasional question on
what does the thermal profile look like, I know what I saved and what I'm
running today are the same.

HI all!

As we are starting to do more and more wave soldering, the question of profiling
and recipe changes has come up.

Specifically, should one run a new profile for every single recipe change?  i.e.
the first profile looked good, but a couple of IC leads aren't soldering as well
as they should, so I want to bump the preheat up a couple of degrees.
Or does one just make the change?

Thanks,
