ProductsKelvin IC Sockets
Advanced Solutions for High-Precision Measurement
Seiken’s Kelvin IC Sockets are built to simplify four-terminal (Kelvin connection) measurements, delivering highly accurate low-resistance testing that surpasses the limits of conventional methods. Designed to support ultra-compact chips—including those smaller than 1mm²—our sockets are perfectly suited for today’s increasingly miniaturized and high-density integrated circuits.
Kelvin measurement demands specialized fixture designs, Seiken provides complete end-to-end support—from custom fixture design to full manufacturing—ensuring absolute integration into your testing environment.
Key Features & Advantages
01 Flexible pin layout for complex testing needs
Unlike traditional sockets, Seiken’s Kelvin IC Sockets allow fully customizable pin layouts, as long as pitch conditions are satisfied. Whether measuring between 100 and 1000 electrodes per chip or conducting simultaneous multi-chip measurements, our solutions offer the flexibility to adapt to a wide range of advanced testing requirements.
02 Easy pin replacement and excellent maintainability
Seiken maintains the same ease of pin replacement as all of our IC sockets, ensuring simple maintenance and minimizing downtime. With small-lot production available starting from just one unit, our Kelvin sockets are ideal for both prototype development and low-volume manufacturing runs.
