Analog and Mixed Signal Devices

cPython Kelvin Contactor/Probe Head – provides superior electrical and thermal performance with significant cost savings. This makes cPython Kelvin ideal for lab and high-volume production test of analog and mixed signal integrated circuits – for applications such as power control, A-D and D-A converters, audio, video, power amplifiers, photonics, optical MEMS and sensors. cPython Kelvin probes are electrically isolated and mechanically independent force and sense paths for true Kelvin contact for taking accurate measurements, even under high current conditions.

cmWave and mmWave up to 100 GHz

xWave Contactor/Probe Head – utilizes patented hybrid contacting technology to optimize RF performance and provide robustness for production testing of the most challenging cmWave and mmWave devices. Inside the xWave contactor are embedded patch antennas and coplanar waveguides for both wireless and wired communication.

High-End Digital Applications to 60 Gbps

ICON Coaxial 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).

High-End Digital and Large I/O Count Devices

Atlas Contactor/Probe Head – offers electrical performance that allows the customer to test to the true performance of the device. Atlas WLCSP test contactors achieve mechanical reliability with a rigid “cruciform” tip applied to Cohu’s QuadTech flat probe technology. The Atlas offers a short electrical path, with lower capacitance and inductance, that is ideal for functional and AC parametric testing of WLCSP devices that require high system bandwidth and throughput gains in large multisite test applications.

High Volume Production Test

cBoa Contactors/Probe Head – 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 homogeneous DUT side plunger provides longer run times between cleaning and increased probe life.

QuadTech Contacting Solution

Mercury Contactor and Probe Heads – 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.

RF Contactor for FBGA and Wafer-Level Packages

ACE Contactor/Probe Head – offers optimal RF performance for fine pitch FBGA, QFN and wafer-level packages for Power Amplifiers, RF switches and mobile communications. Supporting pitches down to 0.4 mm and superior performance for current consumption, gain, standard deviation, and power efficiency.
