Features & Benefits


Mechanical robustness: Rated for hundreds of thousands of IC package insertions for high-volume production test environments
Versatile and cost effective: Easy replacement of contacts to reduce MTBA, improving up-time and lowering cost-of-test
Thermal Conditioning Channels (TCC) Technology: Ability to efficiently thermal condition IC package and test contactor components to maintain ±2°C test temperature
Short Wiping Stroke (SWS) Technology: Micro-wipe provides consistent performance results while minimizing debris generation. Ideal for today’s shorter lead geometry configurations
Advance Contact Finish (ACF) Technology: Extends maintenance intervals by reducing plating transfer buildup and loose debris
