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.

Test Contactor/Probe Head
Atlas
-
QuadTech™ probe solution with cruciform tip strength that stands up to lateral force without bending, plus an enhanced compliance window to accommodate package stack height tolerance.Atlas™ test contactor 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.
