Good morning JF

I believe I know what you are asking.  If I do then this is my reply.

Think of the fractured joint as a dam in a river that flows from one state to another as the Mississippi river. If you remove the dam we have water flow if you leave the dam everyone else is out to dry. So if that circuit is jointed to the other side yes you have a problem.  " I don't know why you would have a two sided board if they were not jointed". 
Question to others , would any one make this type of a board and why?
A two sided board that is not jointed together.

Hi Technetters,

It is stated in IPC-A-610C that a fractured joint is considered defect in
all classes.  Can anyone
confirm that it would be the same if the fracture is on the component side?
And why should
it be considered as defect if the joint on the secondary side is good.
Would the fracture
extend from the primary side to the secondary side?

Thanks in advance...

JF
