2.9 LGA1366 Socket NCTF Solder Joints
Intel has defined selected solder joints of the socket as non-critical to function (NCTF)
for post environmental testing. The processor signals at NCTF locations are typically
redundant ground or non-critical reserved, so the loss of the solder joint continuity at
end of life conditions will not affect the overall product functionality.
Figure 2-7
identifies the NCTF solder joints.
.
Note: For platforms supporting the DP processor land C3 is CTF.
