8. Sustainability Aspects: Obsolescence • Standardized Industry Life Cycle Definition • Standardized Statistical Prediction Tool • Component Life Parameters, u, s • For any given part you must consider; • Part Type and Functionality • Manufacturer(s) and number of sources • Part Technology and Process • Part Package

9. Sustainability 6 Std Component Life Cycle Phases • = Mean (Max) Sales of Unit Components per Unit Time s = One Standard Deviation in Sales/Time

10. Life Cycle of a Component • Special Histogram of Production as Measure by Component Sales/Time (# shipped/time) • Concept Assumes Component Sales follow monotonically increasing to peak, then monotonically decreasing to obsolesence • Life Cycle is Measured Relative to Peak of Sales • +/- 1s from Peak = Mature Product • -1s to –2s from Peak = Growth Product • -2s to –3s from Peak = Introductory Product • +1s to +2s from Peak = Declining Product • +2s to +3s from Peak = Phase Out Product • +3s and higher from Peak = Obsolete Product • Limitations of Product by Demographics, Geographics • Cautions and Warnings • Compatibilities or Incompatibilities • Specific Label Applications or Misapplications • Safety Rules

11. Sustainability Life Cycle of Common Analog IC’s

12. Sustainability Life Cycles of IC Processes

13. Sustainability Life Cycles of IC Process Voltages

14. Sustainability Life Cycle Phases of IC Packages

15. Sustainability Aspects: Obsolescence • For each IC in your BOM, perform an analysis • Separately Consider the 4 Major Aspects • Type (only for analog IC’s) • Process • Package • Voltage • For each Aspect, Find u+(2.5)s, u+(3.5)s dates • Use u, s in years • +2s to +3s from Peak = Phase Out Product • +3s and higher from Peak = Obsolete Product • Find worst case values (earliest of the four categories) • Create a separate IC BOM table of obsolescence analysis with above data • ID all parts above the 2.5s, Separately ID all above 3.5s

16. Obsolescence Table Example • Sample calculations for a few suspect IC’s (Present Date p = 2000.8) • In this case, the present date was subtracted from the window points and any negative value means there is a potential issue

17. Sustainability Aspects: Appendix • Assume Microcontroller is Special Consumer • For Digital and other IC’s don’t use Type attributes
