Mechanical Reliability: Updated Results From A Spherical Bend Test ProgramAuthors: John McMahon, P.Eng., and Brian P. Standing
Company: Celestica Inc.
Date Published: 10/14/2012 Conference: SMTA International
Celestica has been conducting an ongoing testing program to assess Lead free compatible materials and area array packages against the currently accepted levels of process strain. The latest phases of this work have been designed to extend our understanding of component construction dependencies, to begin investigations into some other package types and to compare more materials.
This paper outlines the theory and practice of the test vehicle design, the assembly and test method used to generate data and selected test results. There is also a discussion on the complexities involved in generating predictions of survivable strain in manufacturing operations.
