I think the problem you will find as was explained before is the cost of
these liquids are very pricey and they only make them a few times a year
and if they have non and you want some you will have to wait. Just my two
cents worth.

Guenter,
Thanks for your response. I also had trouble finding a liquid with a
boiling point of 225, but according to an article mentioned earlier (
www.assemblymag.com ) the liquids of different boiling points can be
blended
to achieve what you need.
Thanks,
Jim Kittel

I believe the VP is still a good principle. However, the industrial partner
in LEADFREE that runs the VP trials told me that he has to use a liquid
with
a boiling point of 270 deg.C and that there is nothing available that boils
around 230 deg.
I had problem to believe this but also after asking again I got the same
answer.
Best regards
Guenter
