TFE

TFE supplies the custom-made components that chip makers use to test finished semiconductors before those chips ship inside phones, computers, and other devices.

Specifically, it provides all three elements of what the industry calls 'test resources', test boards, test sockets, and change-over kits, across every major stage of the semiconductor testing process. Listed on KOSDAQ, Korea's tech-focused stock exchange, TFE describes itself as the only domestic company that covers all four sub-processes of chip testing with this complete set of test-resource components. Its customers span chip designers, volume chip manufacturers, and assembly-and-test contractors in both the memory and logic semiconductor markets.
