Tau Series Kelvin Contactors

High precision measurement for advanced, multi-function devices.

Mobility Automotive Industrial Advanced Process
Nodes

In today’s rapidly evolving semiconductor industry, advanced devices demand precise power delivery for
optimal functionality and processing capabilities. Unfortunately, fluctuating resistance in test circuits can
cause false test failures, leading to reduced yield and increased downtime. At TTS, we understand the
challenges semiconductor manufacturers face when it comes to testing high-performance devices. That's
why we're excited to introduce our Tau Series Kelvin Contactors, equipped with custom Kelvin contact
technology for power management and TTS high reliability spring probes for the remaining device I/O’s.
These contactors provide optimal resistance and voltage measurements while reducing the complexity of
the overall design compared to full array Kelvin testing. With TTS’s Tau Series Kelvin Contactors, our
customers can maximize yield, reduce maintenance downtime, and improve the overall cost of test.
