Jim Jenkins nervously writes:

I was just approached by one of our engineers whose customer told her that
the Air Force has issued a directive disallowing the use of no-clean fluxes
on any of their hardware.  The customer is flowing down that requirement to
us.  Do any of you know of this directive or what they could be referring
to?

Doug Pauls, ever calm and collected, responds.

Jim, this is the first I have heard of anything along these lines and we
build LOTS of stuff for the Air Force.  On the other hand, we clean our
hardware, so they may not feel the need to talk to us on this issue.  I
would think that levying such a requirement on *existing* hardware would be
next to impossible since you affect thousands of contracts.  You might want
to determine if this is a requirement for NEW designs.  Since many
companies do manufactur hi-rel equipment with no-clean processes, I would
be curious as to the technical rationale for such a requirement.
