Introducing the 950 Series IC Test Fixture
Ideal for Devices or Packages Under 100 Pin Count
The goal of the 950 Series is to maximize the efficiency and ease of your testing process. It seamlessly integrates with your current test systems and is compatible with both RTI's MultiTrace and Manual Switch Boxes. Whether you're testing devices or packages up to 100 pins, this fixture has you covered with its single Yamaichi 100-pin cable interface.
What distinguishes the 950 Series is its exceptionally low profile. The small size of this design allows for versatile use in cramped spaces, such as under a microscope, inside an environmental chamber, within an EMI shield, or even beneath a Thermal Forcing head. Wherever your testing needs may be, the 950 Series effortlessly adapts, making precise and detailed testing effortless.
Customization is made easy with the 950 Series, thanks to its support for different daughter and extended daughter cards. Breakout areas on these cards allow for the flexibility to add small components or collocate test points for additional hookup opportunities. This makes it easy to adapt the fixture for bench-top testing or other specific needs. Plus, if you need to perform temperature-dependent tests, the heated options with built-in copper heating elements and temperature sensors will come in handy.
Improve your testing process with the 950 Series Test Fixture. It's versatile, compact, and customizable—just what you need for thorough and precise testing in any environment.
Daughter Cards & Extended Daughter Cards for the 950 Series
Daughter Cards
Daughter cards are a pivotal component of the 950 Series IC Test Fixture, designed with versatility and precision in mind. Each daughter card boasts a unique copper pattern that enables semi-permanent programming via solder bridges to VDD and Ground rails. This flexibility allows you to easily customize the card for specific testing needs. Additionally, small SMT components can be integrated between any pin, ground, or V+ to further enhance the card's functionality. Whether you're testing standard devices or need specific custom configurations, daughter cards offer a robust and adaptable solution.
Key Benefits:
- Easy Customization: Quickly program the card to meet your specific testing requirements.
- Enhanced Testing Flexibility: Integrate small components to adapt to various testing scenarios.
- Reliable and Stable: Ensure consistent performance with semi-permanent programming.
- Versatile Connectivity: Seamlessly connect to different devices for comprehensive testing.
Extended Daughter Cards

Extended daughter card with 950 series
Building on the capabilities of the standard daughter cards, extended daughter cards offer additional features for more complex testing scenarios. These cards include a breakout area that merges test points, providing ample space for additional hookups and connections. This design is beneficial when the DUT board needs to be accessed on a bench or under a microscope, as the extended daughter card allows for extensive testing without the direct support of the 950 Series base. With the same customizable copper pattern and the ability to add small components, extended daughter cards ensure comprehensive testing and analysis with greater ease and precision.
Key Benefits:
- All the Benefits of Standard Daughter Cards: Enjoy easy customization and reliable performance.
- Additional Hookup Opportunities: Use the breakout area to add more connections easily.
- Enhanced Accessibility: Effortlessly access the DUT board on a bench or under a microscope for detailed testing.
- Comprehensive Testing Capabilities: Perfect for complex testing scenarios, ensuring thorough analysis.
Meet demanding test requirements with versatile daughter cards and extended daughter cards.
Heated Options
Heated Mini Cards

The heated mini cards feature a built-in copper heating element and a temperature-sensing device. These cards rely on the 950 Series base to provide signals to the pins under test and monitor temperature. The operation of these heated mini cards requires RTI's temperature controller to ensure precise thermal regulation during testing.
Heated Socket Lids
Unlike the heated daughter cards, heated socket lids connect directly to the temperature controller. These lids do not require a heated 950 Series base, making them versatile for various testing environments. They provide an efficient solution for temperature testing by contacting the topside of the DUT.
Heated 950 Series Fixture Base

Heated 950 series connects to temperature controller
The 950 Series base is available with or without heater interface components. The heated base version integrates seamlessly with other heated options, providing a comprehensive solution for temperature-controlled testing. However, bases without heater interfaces may not be upgradable, so selecting the correct model for current and future testing needs is crucial.
Temperature Controller

Temperature controller manages heated 950 series
RTI's temperature controller is designed for device-level thermal regulation in a compact, benchtop form factor. It uses a single loop dual output temperature control system with Auto Tuning (AT) and precise PID control capabilities for fast and accurate performance. The controller manages temperatures from ambient to +100°C, with custom configurations available for higher temperatures. Temperature measurement is performed using a thermocouple or a thin-film RTD sensor embedded in the copper heating block, ensuring accurate monitoring close to the DUT.
The heated options for the 950 Series IC Test Fixture provide a versatile and comprehensive solution for temperature-sensitive testing applications. Whether using heated daughter cards, socket lids, or the fixture base, RTI ensures precise temperature control and reliable performance for various testing needs.
