talking only about bipedals here.

(I don't think a small hot air pencil is good for ICs? enough volume?
i thought i will continue to use the hot air gun for the ICs, but it is 
clumsy
for the tiny ones...)

it is a question of "i have only time to build one - which one is better".

I hope to use the same compressor as i use for the solder paste dispenser,
so the air source would have a nice regulator. I also plan to use
the other side of the compressor for a vacuum (for now only manual) PnP.
I tried to use it as a "solder sucker" already, and it works.


By the way, another question, why is there no aluminium used for 
desoldering tips?
is it not making enogh contact to heat the joint? it would not be consumed
like copper and those rivets are just the right size... (good thing there 
are
ones of copper too... exchangeable and VERY cheap solder sucker tips: pop 
rivets.)

Well, i will see if i can make a appropriate heater for the hot-air...
