REL-2079 -C-A Reliability Report for AME4624/4625 Series Product Approved by Prepared by Amy Shen Quality & Reliability Dept. Manager Eric Chen Quality & Reliability Dept. Engineer Conclusion: The AME4624/4625 series product has successfully met AME’s reliability standard that is required on all AME, Inc products. Furthermore, QRA Dept. of AME, Inc monitors the reliability continuously to make sure that all AME4624/4625 series product will still meet AME’s reliability standard in the future. Table of Contents: Ⅰ、General Description Ⅱ、Product Information Ⅲ、Failures In Time Calculation Ⅳ、Product Reliability Test Result Ⅴ、Package Reliability Test Result Ⅵ、IR-reflow Test Result Ⅰ、General Description: The AME4624/AME4625 analog switches feature low ON resistance, single-pole, double-throw (SPDT) with wide operating single power supply voltage range, from 1.8V to 5.5V. The AME4624 offers break-before-make switching while the AME4625 offers make-before-break switching. AME4624/AME4625 has 1Ω max ON resistance when +5V power supply is used. These products also have fast switching speeds, tON = tOFF = 50nS max. AME4624/AME4625 are available in SOT-26 & TSOT-26. Ⅱ、Product Information: Ⅲ、Failures In Time Calculation: Use HTOL test information mentioned in sectionⅣ, FIT (Failures In Time) can be calculated as below: FIT = ( x 2 (ν , CL ) × 10 9 ) /( 2 × S × H × AF ) = ( 4 .61 × 10 9 ) /( 2 × 77 × 1000 × 280 .59 ) =106.69 (pieces per 109 hours) @ 40℃ with 90% Confidence Level. Where AF is acceleration factor setting activation energy to 1.0eV as zero failure.
