Appendix A Analytical tools






A.1 Introduction

Analytical tools are necessary to insure high-quality, high-reliability semiconductor packages for end market use, and are employed for quality assurance and reliability testing. And in the unlikely event package failures do happen, analytical tools will facilitate the failure analysis to determine the root cause.

A.2 Types of analytical tools

Basically, there are two categories to consider: destructive and nonde-structive. Logically, it makes sense to employ nondestructive tests first, especially on live parts in a quality assurance situation or when the number of samples is limited to a few or one. Once nondestructive testing is exhausted, destructive tests could be turned to for further ...
