Hi Miguel!

I'm assuming you mean BGA sockets. There's two companies that know of that do
production sockets for BGA's, you might check them out. One is Advanced
Interconnection Corporation, check their sockets out at:

http://www.bgasockets.com
They have sockets that also incorporate heat-sinks in them...pretty
cool...literally..hehehe.

Another company is Wells CTI. They make what they call "Z-Lok" sockets. You
can put a BGA  in them and because of the way they grip the balls, it doesn't
deform them, so you can still put the BGA directly on the PCB after it's been
in the socket if you wanted to. You can view their sockets at:

http://www.wellscti.com/zlok.htm

One thing I'm familiar with about the Wells CTI socket is that it is a
'friggen BEAR to rework if you mess-up and don't get it down right the first
time!!! Some of you may recall my little "adventure" with this puppy about a
year ago...hehehe
