SOLDER RELIABILITY SOLUTION SOFTWARE: APPLICATION NOTES
AVAILABLE UPON REQUEST TO LICENSED USERS OF THE SRS SOFTWARE

A few application examples giving input parameters (as entered in the SRS software) and comparison of life predictions to
accelerated test results. Input data is tabulated in detail so you can replicate the analysis for yourself.

 AN # 1: "Comparison Of CBGA And LCCC Failure Data And Life Predictions", EPSI Inc. Technical Note,
1999.

Validation of SRS model against thermal cycling test results for LCCC & CBGA assemblies.
CBGA analysis files available upon request. Ask for files: CBGA200L.SRS and CBGA300S.SRS.

AN # 2 available as .pdf file (3 pages).

 AN # 2: "Fine-Pitch PQFP Assembly Reliability", EPSI Inc., Technical Note, Jan. 6, 1999

Illustrates the application of the SRS model to PQFP assemblies. Two independent examples.
Includes review of test data, tabulated input, and comparison of test failure times to life predictions.
PQFP analysis files available upon request. Ask for files PQFP_L.SRS and PQFP_Y.SRS

AN # 2 available as .pdf file (3 pages).
