MK..


nicely pointed out...

IconicPCB:
Is stainless steel really a requirement?

I mean if fluid is inert it ought not contribute to corrosion process in any way.

Why does it need to be stainless steel why not ordinary galvanized sheet metal ?

zapta:
Can't this type of reflow be achieved using less expensive liquids?  For example, using a pressure cooker to increase the vapors temperature.

IconicPCB:
A pressure vessel brings in problems of its own.
Licensing of operator and inspection of equipment come to mind immediately.

Trying to achieve the thermal profile I suspect becomes a bit more complicated.

I was thinking of a home setting for hobby purposes.  Profile may be controlled by controlling the pressure in addition to the heat and possibly using solder paste with lower melting temperature.

Edit: Glycerin for example has a sea level boiling temperature of 554F,
