1.Can you please explain what
a Flip chip is, I know it is a processor but why is it called
Flip Chip is a relatively new technogy
that enables PIII to be manufactured in socket 370 format
Intel refer to it in their prcessors as
"flip-chip pin grid array, or FC-PGA"
It comes from a company called Flip
Chip Technologies who license the technology out.
The technology itself is to do with the process called "wafer
bumping" which involves creating a solder "bump"
on the main silicon wafer. This bump is used to take the signal
out of the processor on its journey to the pins that connect
it to the motherboard.
As chips become faster then the number of
circuits on a single chip increase and the "width"
of the silicon tracks on the wafer decrease. This means that
newer technologies such as flip chip are required in order
to get the signals out of the wafers reliably. The faster
pentium III procesors for example use flip chip technology.
