The FORMULA® HF Ultra Test System is a functionally complete automated means of measurement for VLSI circuits and provides:
- High readiness of equipment for measurements and tests
- Automation of all stages of the measurement process and data management
- High-speed Multisite mode
- Operating modes with automated probes, automatic loaders, test equipment and instruments
- Reliability in round-the-clock operations
- User-friendly, fully functional software
- Quickly interchangeable test fixtures
- Automatic diagnostics and metrological calibration
FORMULA® has modular bus architecture that implements the principle of custom configuration of equipment with a choice of primary and secondary devices corresponding to the range of measurement and testing tasks.
Use of the FORMULA® HF Ultra for testing of VLSI circuits under the environmental conditions
The design, hardware and software of the FORMULA® HF Ultra Test System create optimum conditions for testing microcircuits, including for testing combined with measurements, for example, using ThermoStream units and flow climatic chambers.
Measurements under temperature effects directly on the spring base, without using cables, and without loss of signal quality are supported.
One of the priorities in the design of the system was to develop methods for the ATE to signal transmission back and forth to the device under test (DUT) with minimal signal loss and distortion.
An original new-generation contact system, designed for measurements under both normal conditions and in the temperature range from –60 °C to +125 °C, was developed especially for the FORMULA® HF Ultra Test System.
Reliability, convenience, fast installation, and attachment and replacement of test fixtures are achieved by using a precision spring device, special frames for large test fixtures and POGO-PIN contacts that guarantee at least a million test fixture connections.
The ATE is equipped with means for integration with external equipment, including probes, test equipment and external instruments.
The measurement unit rotation manipulator has an electrical lead with electronic control, which provides optimum workstation ergonomics in all operating modes.
FORMULA® HF Ultra Test System software complex
The FORMULA® Test System software complex FormHF is the GUI-based environment designed for all stages of the measurement process.
The FormHF software complex is essentially a system for automation of the laborious process of development and debugging of test programs which has been adapted for use by a wide range of technical specialists without using programming languages. It supports all standard methods for testing microcircuits.
Graphic interpretation of measurements enables fast assessment of measurement results reduces the time for test development and debugging to a few days.
Test fixtures
The FORMULA® delivery package includes standard installation frames for test boards and complete documentation for independent development of accessories by the Client.
The design of the frames permits accessories of various dimensions.
