Gosh, with all due respect, I'm sure the equipment is using the Galden 
fluid for vapor and that drag out if any is minimal. No environmental 
concerns as far as I can tell.

I think vapor phase will be the comeback kid in the years to come because 
of the even distribution of heat. (We do not have any lead-free soldering 
issues here)

What I'm really talking about out is how inconsequential our impact on 
global warming compared to the enormous volcanic eruption in Chile. Some 
of the photo's are incredible. Maybe Steve can post them. I think they are 
available from the UK's Daily mail website.

What's happening right now in Chile is a huge environmental disaster and 
no one, no laws, no regulations can do anything about it. It just shows 
how inconsequential we really are.

Re: [TN] Vapor phase






Ioan,
Ask the supplier what is the global warming potential of the materials
they are proposing as the thermal transfer material.  Then you have to
decide if you can live with the answer.

Also, RF cans with small holes can be problematic.

Subject: [TN] Vapor phase

Dear Technos,

 

I would like to get your expert opinion on the latest developments in
the vapour phase technology. The last time this topic has been discussed
here this was still an environmental hazard.

 

Here's the latest sales pitch:

 

Dear Convection Oven Users:

With Energy Costs Skyrocketing, You have a cheaper, efficient, and a
better yield Alternative!!

Low Operating Cost, 110 Volt Machine, Run Lead and Lead Free
Sequentially!! 

High Yield, Run your Lead Free Boards at 230 Degrees Uniform Temperature
Distribution, No Circuit Board Delamination, Uses Environmentally
Friendly Teflon 2 Liquid No Hazardous Florocarbons!

 

The questions are:

*       Are the advantages real, should I prefer vapour phase over
convection in day by day reflow operations, from the technical point of
view?

*       Would the technology finally be environmentally friendly?

 

Thanks,

 

Ioan
