Test Contactor/Probe Head
cBoa
-
cBoa™ test contactors and probe heads are the solutions 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.The cBoa features a stainless-steel spring for tri-temp testing and performs in operating temperatures of -55°C to +155°C and bandwidth of up to 35 GHz @ -1 dB.

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.

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.

Test Contactor/WLCSP Probe Head
ACE
-
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.

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.
