Contactor - xWave

Minimized number of connection interfaces

→ Best signal quality

→ Highly reliable and robust

→ Best suited for production environments

→ Patent # 9842793

→ Additional Patents Pending

PCB

Coplanar waveguide on leadframe

Spring probes connect through regular PCB traces

Contactor - xWave

Wafer level probe solution up to 100GHz and pitches down to 100um

• Shortest signal path from die to tester bypassing PCB

• Same core technology used for package test on handler

• Field replacable spring probes, leadframes, connectors/waveguides

OTA is actively running in volume production at a European IDM

Summary

– Main growth markets

• Diffuse market boundaries

• Both IoT and ADAS applications use 5G infrastructure

– Production equipment

• Diffuse boundaries – Handler/Contactor/Tester are an

integral part of the cm and mm wave test solution

• Contactors and test instrumentation both define test

quality

• Embedded antennas require handling equipment to offer

part of the signal conduit
