Abstract:
1. A method for tracing die units during manufacturing operations, comprising: assigning a first index string to a plurality of die strings that are in one-to-one correspondence to a plurality of die units, wherein the plurality of die units is associated with a source object, wherein ranges of indices encompassed by the first index string identify corresponding die strings of said plurality of die strings; upon transferring at least some of the die units from the source object to a receiving object, copying the plurality of die strings associated with the plurality of die units from the source object to a receiving object; assigning a second index string to the die strings associated with the die units transferred from the source object to the receiving object to indicate die units transferred to the receiving object; adjusting the first index string assigned to the plurality of die strings corresponding to the plurality of die units associated with the source object to create a third index string to indicate die units remaining in the source object; and associating the third index string with a plurality of die strings corresponding to the plurality of die units remaining in the source object.
