They seem to spawn randomly in missions, sometimes replacing Cephalon Fragments.

However, it might also seem that if all cephalon fragments has been scanned for a certain planet/tile the Somachord fragments are guarateed to spawn (Got all 4 fragments for the grineer onslaught track in a row after finishing all cephalon scans)
