Elastomer-Free Cantilever Test Interface for Maximum Reliability and Yield
Durable. Long Lifespan. Higher Test Yield.
The ULTRA®-S cantilever spring contactor is engineered for high yield and consistent performance in the most demanding environments. Unlike traditional elastomer-based interfaces, ULTRA-S eliminates performance degradation caused by compression set, temperature, and humidity exposure.
- No Elastomer Degradation: Avoids the compression set and humidity effects typical of elastomers, ensuring stable mechanical and electrical properties over time.
- Superior Electrical Consistency: Reduced contact resistance drift and mechanical variability result in higher and more stable test yields.
- Lower Maintenance, Higher Uptime: With no elastomers to replace or manage in inventory, the system delivers increased test cell uptime and reduced maintenance costs.
Technical Advantages:
- Supports Kelvin Test at 0.4 mm pitch and above
- Handles high-current applications where conventional probe-based contactors fall short
- Stationary board contact design eliminates wear and extends contact insertion life
- Scales efficiently in high-parallel test setups, maintaining uniform contact force across sites
- Addresses RdSON-related probe contact issues
- Optimized for board pad offset and variable contact height scenarios
