ESD SP5.2.1:2012

This standard practice establishes an alternative test method to perform Machine Model (MM) component level electrostatic discharge (ESD) tests when the component or device pin count exceeds the ESD simulator tester channels. This alternative test method (Supply Pin Ganging) is limited to components with greater than 512 pins or balls. Since many of the tester parasitic properties of a higher pin count ESD simulator cannot be reproduced using a low pin count ESD simulator, the test results will be similar, but not identical. This document references ANSI/ESD STM5.2 (MM) test method which will override this standard practice (ANSI/ESD SP5.2.1) if there are any conflicts in testing a component. If an ESD simulator above 512 pins is not available, then this standard practice can be used as a guide to ESD stress components with greater than 512 pins or balls using a lower pin count ESD simulator.
