There is really only one benefit: Low cost of ownership. The advantages listed above result in low initial cost, high test yields, and long probe life – all the necessary ingredients for low cost of ownership. And these benefits are available in test contactors (sockets) / probe heads that support a huge variety of device types, plating, pitches and application requirements.
cBoa Contactor / Probe Head
Uncompromised performance radial probe for the toughest test conditions
cBoa contactors and probe heads are the solution for contacting high frequency devices for package test or final test at wafer. The robust design and materials of the cBoa probe withstand the rigors of high-volume test by providing longer life and higher yield. The homogenous DUT side plunger provides longer run times between cleaning and increased probe life.
The cBoa features a stainless-steel spring for tri-temp testing and performs in operating temperatures of -55°C to +155°C. With a bandwidth up to 27 GHz, cBoa can be used to test some of the highest frequency devices.
The enhanced compliance window accommodates package stack height tolerances well.

Gemini Kelvin Contactor / Probe Head
Industry preferred high performance, high value, low cost true kelvin QuadTech contacting solution
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.
At 3.22 mm test height, the Gemini Kelvin is an excellent all-around spring probe with low inductance, high bandwidth, and excellent current-carrying capacity. The 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.
ICON Coaxial Contactor
Coaxial production solution for testing high end digital applications to 60 Gbps
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 ICON’s 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).
Mercury Contactor / Probe Head
Industry preferred high performance, high value, low cost QuadTech contacting solution
Mercury probes and contactors are excellent spring probes for the laboratory though they were designed with the robust qualities needed for high-volume production test. Their unique design ensures excellent plating quality for low, consistent resistance, long life, and high-test yields. Mercury probes are available with minimum pitches of 0.3 mm, 0.4 mm, 0.5 mm, and 0.8 mm, to provide the best performance at any device pitch. Mercury probes have bandwidths of up to 22 GHz, and can carry over 3 Amps of current. The Mercury is an excellent choice for any test application.
