Test Procedures, Calibration Procedures, Replacement Procedures
Typical Replacements Include
Batteries
Sensors
Filters
Mechanical Wearout Components such as drive belts, pulleys, etc
Manual Section should show pictoral and textual replacment steps
Manual should indicate who should perform the maintenance (authorization, training level, etc)
Relationship to product warranty

5. User Manual
Service
Specified for repairs above and beyond normal maintenance
Service Strategies Include (Select 1 or more)
Field Repair by User
Requires service manual and replacement part depictions
Requires a concise list of replacement parts and procurement
Specialized Service Center
Requires specific replacement parts list
Specific testing equipment and skills
Factory Repair or Replacement
Still Requires replacement parts list documentation
Requires repair process chart (mimics mfg test processes)
Assembly/Dissassembly
Default-Disposal
Requires disposal strategy, No repair strategy
Must identify specific disposal procedures for ALL batteries

6. User Manual
Warranty
Specified for a period of time or number of operations
Must specify how to exercise the warranty
Teams should show (in ppt slide) relationship between warranty period and reliability calculations
Reliability analysis yields MTBF
MTBF under simplified conditions indicates when ~63% of population has failed
In genral, Warranty Period << MTBF

Corrective Action

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 = )
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
