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
