Ron,

I have been looking into the same subject (the compatibility of no clean 
fluxes with Fluorinert.)

Some of our assemblies operate while immersed in Fluorinert.  The Fluorinert 
is used to provide cooling and prevent arcing (due to the high dielectric). 
 I am wondering if no clean flux could react with the Fluorinert (which in 
my experience is anything BUT inert).

I am also wondering about the use of no-clean flux in general when 
associated with high voltage (up to 12 kV) circuits.  Does the no clean 
residue decrease the dielectric withstanding voltage?

     Hello TechNet!

     Does anyone have any experience with No-clean flux and Flournert.
     Flournert is an inert liquid, I understand, however, will it or
     No-clean flux be affected by one or the other???

     Flournert is used in Vapor Phase operations and potentially other
     uses.  Will it affect the No-clean flux or will the No-clean affect
     the flournert?  I guess compatibility is the word?

     Are there any flournert suppliers, flux suppliers, chemists, or folks
     who have got some experience in this area??  I would appreciate some
     education on this subject.

     Thanks
     Ron H
