Kelvin Test Contactor/Probe Head
Gemini
At 3.22 mm test height, the Gemini™ Kelvin test contactor is an excellent all-around spring probe with low inductance, high bandwidth, and excellent current-carrying capacity. The device under test (DUT) side tip design accurately maintains its 100 µm spacing for the life of the probe. Customers report typical probe life of 500 k to 800 k package insertions, or over 2M touchdowns at wafer-level test. The offset tip allows manageable board layout with a board-side spacing of 0.4 mm.Gemini Kelvin probes and contactors provide a first-rate solution that effortlessly makes reliable, true Kelvin contact for high-volume final test of both singulated packages and wafer-level devices. Gemini Kelvin is an ideal solution for devices such as power controllers, A-D and D-A converters, power amplifiers and audio and video circuits.

Coaxial Test Contactor
ICON
The ICON™ test contactor designed specifically for maintaining the native impedance of the device-under-test (DUT) through the contactor to the test system, maximizing high frequency power transfer by minimizing signal reflections (Return Loss).The metal body is a Faraday shield/cage, which reduces cross talk (electromagnetic radiation) the primary cause of signal jitter. Along with this, the aluminum body blocks both static and non-static external electric fields (random noise). Featuring exceptional DC and RF performance and excellent thermal management.
