Characterizing materials and components |
Characterization methods for any new materials or components proposed Plan for tracking and managing lead-free electronics (LFE) Plan for addressing Parts Integrity |
Component and materials criteria established Parts obsolescence issues defined Identify initial LFE, risks, & mitigations Parts Integrity requirements & processes defined |
Parts obsolescence issues addressed LFE items and issues addressed Processes that prevent Parts Integrity risks implemented & initial risks identified |
Identification of all LFE items used, identification of risks, and mitigations in place Verification of Parts Integrity via approved procedures Parts Integrity risks identified & mitigations in place |
Establish suitable replacements for discontinued components Implement LFE mitigations Replacement parts meet same level of integrity as original parts |
