Automatic Test Equipments Are For Integrated Circuit Testing

The testing equipment used to detect faults in the operation of electronic devices by creating stimulus signals and capture responses from electronic devices under test is known as electronic test equipment.

Automatic test equipments are for integrated circuit testing.

The major draw back of this scheme is the huge monetary cost of an ate. Ate tests can be both simple and complex depending on the equipment tested. Automatic test equipment or automated test equipment ate is any apparatus that performs tests on a device known as the device under test dut equipment under test eut or unit under test uut using automation to quickly perform measurements and evaluate the test results. A wafer prober is a machine automatic test equipment used to test integrated circuits for electrical testing a set of microscopic contacts or probes called a probe card are held in place whilst the wafer vacuum mounted on a wafer chuck is moved into electrical contact.

In circuit test equipment provides a useful and efficient form of printed circuit board test by measuring each component in turn to check that it is in place and of the correct value. Automatic test equipment ate is a machine that is designed to perform tests on different devices referred to as a devices under test dut. If any faults are detected then identified faults can be traced an rectified using electronic testing equipment. An application specific automated test equipment system for testing integrated circuit devices is described.

Automated test equipment automated test systems automated testing equipment automatic test systems. Automatic test equipment ate refers to any equipment used to perform assembly line type testing of produced items. Generally the term is applied to equipment that is used in testing integrated circuits and printed circuit boards during the manufacturing process. As most faults on a board arise out of the manufacturing process and usually consist of short circuits open circuits or wrong components this form of testing.

Testing modern vlsi circuits is a complex affair. In one embodiment of the present invention the automated test equipment system includes an interface board that recreates the native motherboard environment of the device under test. Industries use a fully automated test setup called ate automatic test equipment which comprises of almost all standard test equipments controlled by a central controlling unit. An ate uses control systems and automated information technology to rapidly perform tests that measure and evaluate a dut.

The critical part of the machine involved connecting the integrated circuit ic to a differential pressure source while establishing electrical connection to the ic for flash programming of the ic with quadratic linearization coefficients. The testing usually takes place in a production environment where automated relatively high speed testing is important.
