it looks like a gun, and has a hole in the end of its big fat tip to 
suck solder out as it melts... very handy, but expensive.

if you don't have one, the best option is to cut apart the socket with 
the knife you are using for the board rework.

just take it slow and careful, and don't overheat any of the PCB holes, 
and you'll be fine.

I recommend using desolder braid for cleaning the holes. those desolder 
pump things never do what I want... or maybe I only ever tried cheap 
crappy ones??

NOOOO!!!! don't "repair" previous mods!!!
:-)

my board has those too.

they are already done, and make your usint work as it's meant to, as is.

the new mods on top of the old mods make your board work as you want it to

just remember - nothing is particularly hard, but you need to be slow 
and deliberate with what you do.

"measure twice, cut once"

also, try and be as non-static as you can be when handling the board - 
don't wear polyester and shuffle your feet on carpet.
:-)

if you have any static dissipative plastic (silver or pink - used in 
packing sensitive electronic stuff) use that when moving about with the PCB.




anyway - I ended up going and helping my mum change over her outlook 
express archives on her old computer to outlook on her new 
comnputer..... so that was a fine way to burn an evening, and I got no 
further with my mods.

I'm still hoping to have a report on my finished rev2 emax board by the 
end of the week.
