In this study, we use equipment measurement, mathematical modeling, and finite element analysis (FEA) simulation to observe the probe mark on the wafer bump.
Semiconductor packaging companies must perform wafer acceptance tests to qualify their copper pillar micro-bumping process.
Welcome to Level 3, Lesson 2 – All About Bump Testing, part of CTC’s free online vibration analysis training series. We hope you enjoyed and benefitted from the previous course and will continue to build your vibratio...
• Mean velocity and turbulence stress components computed in the Cartesian coordinate system are transformed to the local orthogonal coordinate system at a given location on the bump surface using the local wall-norma...
Plateau bump functions. Bumpfunctions can be made to have a nice prop-erty: they can have a plateau, by which we mean a nonempty open set in which the function is identically 1.
In an effort to identify potential methods to quantify the bump magnitude at bridge approaches, this TechNote provides background information on the concept of surface profile measurements and methods to quantify the ...
This manual is a guide advising what to consider and how to perform an optimal Cold Bump Pull (CBP) test. This manual focuses on solder ball testing, but the principles apply equally to most bump testing.
