There is a requirement of fast DC test such as open/short of any DUT pins, though complete performance test is not requested. Simplified IC test before and after burn-in, screening before the final test or before shipment are some of these examples.For this type of application, fast and inexpensive open/short tester is more suitable than the full DC tester that has plentiful test functions. ESPIER 2001 is suitable for such an application. Not only open/short test but a little more sophisticated test such as input leakage test, supply current test and write/read test of a specified memory location may be included.
