Interconnects are critical to the formation of electric circuits that are used to realize electronic devices. With the continued growth of heterogeneous integration and the every expanding array of electronic devices, the ability to predict the life expectancy and damage state of electronics is critical. The adoption of new materials, new end use applications, and new package geometries presents a perpetual challenge to the reliability scientist tasked with assuring a low risk for failure during warranty and/or mission period. To the end, CALCE is dedicated to:

  • Providing failure models and analysis methods for estimating life expectancy of solder interconnects.
  • Providing constitutive and fatigue model constants for relevant solder materials.
  • Providing analysis of relevant factors that may influence solder interconnect life expectancy.
  • Providing test methods and interpretation of test results for assessing interconnect field life and improving interconnect life estimates.
