RF (cmWave) Probe with Bandwith up to 40 GHz, Homogeneous Tip, and Long Life

ACE™ test sockets offer 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, ACE features an innovative design that provides superior performance, improved yields and power efficiency.

ACE probe heads deliver exceptional electrical performance, both DC and RF. Manufactured from HyperCore™ base material, a proprietary material of Cohu’s Everett Charles Technologies, ACE probes have the electrical properties of BeCu with the non-oxidizing properties of a precious metal. The short signal path, sharp tips, and large contact area between plungers provide high current conductance and reliable contact with less force.

Compatible with all device types and platings; suitable for all test applications, including singulated devices, strip test and wafer-level test. The electrical and mechanical performance of ACE, combined with a long probe life, deliver a low overall cost of test, which is unprecedented for RF contactors.
