Most ICs are tolerent to 400 degrees celsius for up to 10 seconds when
heat is applied to the pin. In IR assited reflow ovens, most
components on the board are subject to 275 degree C heat upwards of 45
to 90 seconds. Total reflow process time for surface mounted
components in a reflow oven is between 5 and 7 minutes. Most of that
will determine the pallete material that act as carrier for the PCBs.

FR4/5 laminate material will withstand heat around 300 degrees C for 7
to 10 minutes without discoloration or delamination.

I haven't had a chance to see one in person. But from the commercial, it
appears to look like an arc. That can't be good for sensitive electronics. I
think I'll stick to my Hakko or my butane until I've had a chance to use
one.

No it is not an arc. One possibility is a conductive ceraminc alloy.
That would at least explain the rapid heat and cool down periods.
There are ceramics that can conduct and dissapate heat rather rapidly.

As for the Hakko, the hot air Hakko reflow units are real good for
surface mount devices. The only other item that I found better for
large ICs, 208 pin TQFPs is a hot plate.

Depends what you're soldering... for very small low mass jobs... that
cool heat soldering iron might be fine. For electronics work...
probably not very useful.

I did and every time I needed it for what IT IS, it worked very well.

Still using the same batteries it came with. At least a year now. Used it
about 6 times
in situations that required a device as it is advertised.

How many watts is one of these things equal to?

You want that in "Bird" watts?

LOL... think you've exposed the root problem here. That thing couldn't
be anywhere near the power of a regular soldering iron in the 30-50W
range.

That type of soldering iron is not intended for that kind of use.
Instead it is actually a good iron for small surface area heating and
even surface mounted parts.

Alkaline AA batteries are rated between 1600 to 1900 milliamp/hour.

Well... you guys can play around with your little toy soldering iron.
I'll continue to use my http://www.hexaconelectric.com/thermo.html
