Purpose:
This experiment documents and monitors tin whisker growth on one lot of pure tin-plated multilayer ceramic capacitors (MLCCs) mounted inside a hybrid using conductive (silver) epoxy and then subjected to extensive thermal cycling followed by long term ambient storage.  The experiment was initiated in 2001 by a non-NASA entity who then donated one of their test samples to NASA Goddard tin whisker researchers for continued monitoring.  Details of this study and interim observations were formally published in June 2002 at the American Electroplaters and Surface Finishers (AESF) SUR/FIN conference in Chicago, IL.  The paper also discusses similar but unrelated experiments by others attempting to induce whisker growth on tin-plated MLCCs.
