Hello Victor,

There is no allowance for a fractured solder joint as any fracture can
further propagate during thermal cycling and cause an open circuit.

Fellow TechNetters:

   Is there a percentage associated with the statement "Fractures Solder" in
the above stated IPC STD section?
I did not a similar statement, Fractured Solder, for Surface Mount Devices
and Surface Mount Area.
Is there an acceptable percentage of the solder joint lead interface that
can be fractured?


Victor,
