SENTRY is a handy and convenient to use tester, aimed at goods inwards inspectors and designed to measure the unique electrical signature (PinPrint) of components. The information collected is managed through a database and is used to compare known good devices against suspect components. Typically, SENTRY can easily detect missing or incorrect dies, lack of bond wires, inaccurate pinouts, and pin impedance variations. Simple pass or fail results are returned after testing, offering a high level of confidence in the authenticity of components.
