Description of calceFAST "Plug-ins"

• calceFAST includes the Failure Model Analysis Manager which provides an interface to CALCE Failure and Analysis Plug-ins.

• Failure Model Plug-ins included with calceFAST include modeling solder fatigue for BGA, CSP, PLCC, PQFP, LCR, LCC and LCCC packages. It supports different interconnects type like, J-lead, gullwing, thruhole, PGA, solder-ball and die inserton mount packages.

• Many failure model plugins provide the ability to simulate the effect of multiple stress conditions, modify distribution parameters, refine different material and stress types with adding capabilities and export-import different package types.

• In addition to applying multiple stress conditions, many failure analysis plug-ins allow you to conduct a Monte Carlo simulation. This capability allows you to obtain failure distributions based on defined distributions on model inputs.

• The software also includes a Statistical Analysis Plug-in using Weibull, Lognormal and Normal distributions.

• A failure model plug-in for fatigue analysis for plated through holes which estimates PTH fatigue life when PTH is subjected to repeated thermal cyclic loads is provided. This plug-in can be used to calculate stress and strain inthe barrel with cycles to failure.

• A failure model plug-in for assessing the overstress failure due to a imposed shock load is also provided. This plug-in allows you to determine whether a part attach will survive a given shock load.

• In addition to the Failure Model Analysis Manager, the calceNFEM is also provided. CalceNFEM is a nested finite element program that allow the user to examined durability of BGA interconnects.
