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.
