Elmer; Thanks for the response, I know the smaller devices can be fully tested before packaging, and I has felt that they would test the CPUs that way prior to packaging, as the packages are very costly.
I have seen these multiple finger test jigs being used on entire wafers, touching the pads for testing, and then advancing to the next die. Is this just a quick go/nogo test for CPUs such as these, to winnow the candidates prior to full packaging?

I would think they would be able to make a single die tester that would be able to at least determine if they had a fully functioning device after the on wafer testing had cut down the numbers.
