Test Contactor
MiCon
-
The MiCon™ Test Contactor is spring pin footprint compatible supporting advanced temperature requirements as well as advanced power/current requirements. The footprint compatibility allows for easy and cost-efficient conversion from spring pin setups. The fully decoupled load board side of the spring ensure no degradation of the load board pad.MiCon features a single piece design, which ensures a long lifespan, low and stable contact resistance, high current carrying capability and an extended temperature range. The MiCon allows for testing at full specification values. The extended operating range accommodates device lead trim and form variability such as device alignment accuracy and device lead coplanarity.

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.

Test Contactor
cDragon
-
cDragon™ Test Contactor pin’s thermal design supports fast temperature control response and stabilization for repeatable at temperature testing of devices in a handler environment.The homogenous MEMS elastomer-free multi-beam pin delivers long life and high wear resistance. By design the cDragon’s pin decouples insertion motion from the test-interface-board side of the pin. This eliminates test-interface-board pad wear.

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.
