How would you control an assembly with a fractured solder joint and keep the integrity of the solder joint?  The solder joint could easily continue to degrade and cause field failures.

The IPC standard states that all clipped leads must either be reflowed or checked under 10X magnification. Is this just a standard for single sided boards? If you have a double sided board and a good fillet on the component side of the board and you clipped the leads on the solder side what would be the cause of concern if a joint is fractured on the solder side?
