Description

Kelvin Four-Wire Testing (4-Wire Kelvin Method)

Also known as 4-Terminal (4T) Testing, 4-Wire Testing, or 4-Point Probe Method, this is an impedance measurement technique that uses separate pairs of current-carrying and voltage-sensing electrodes. Compared to traditional two-terminal (2T) sensing, Kelvin testing allows for significantly more accurate measurements by eliminating lead and contact resistance errors.

Currently, this method is primarily used for circuit testing in SOP (Small Outline Package) devices, ensuring high precision in resistance measurements for semiconductor validation, quality control, and R&D applications.

Why Choose Our Kelvin Test Sockets?

1. Unmatched Precision for Demanding Measurements

Our Kelvin test sockets leverage true 4-wire (4-point probe) technology, eliminating lead resistance errors for high-accuracy impedance measurements—critical for SOP, QFN, BGA, and advanced IC packages.

2. Engineered for Reliability & Repeatability

  • Gold-plated spring probes ensure <10mΩ contact resistance and long-lasting performance.
  • Self-cleaning contacts reduce maintenance downtime in high-volume production testing.

3. Customizable Solutions for Your Needs

  • Optimized for your specific package type (SOP-8 to BGA-256+) and frequency range (DC to 6GHz+).
  • Modular designs support quick conversion between different DUT interfaces.

4. Speed Up Your Testing Workflow

  • Low-insertion-force (LIF) design prevents device damage during placement.
  • Compatible with automated handlers for high-throughput production environments.
