A method of testing integrated circuit die for presence of a crack includes performing back end integrated circuit fabrication processes on a wafer having a plurality of integrated circuit die, the back end fabrication including an assembly process. The assembly process includes a) lowering a tip of a first manipulator arm to contact a given die such that pogo pins extending from the tip make electrical contact with conductive areas on the given die so that the pogo pins are electrically connected to a crack detector on the given die, b) picking up the given die using the first manipulator arm, and c) performing a conductivity test on the crack detector using the pogo pins to determine presence of a crack in the given die that extends from a periphery of the die, through a die seal ring of the die, and into an integrated circuit region of the die.
