MPI Corporation — AI supply-chain exposure

MPI Corporation supplies the probe cards and engineering probers used to test chips at the wafer stage, the tooling that touches each die to check it works before it is cut and packaged. Its reach into logic, RF and photonics test gives it a foot in the parts of the chain, like optical interconnect, that AI networking increasingly leans on. It is a picks-and-shovels vendor to the verification step: as devices grow more complex and harder to prove out, that test tooling becomes a quiet gate on how fast good silicon can actually ship.
