Why EOL Parts Sourcing Demands Structured Control
Primary Supply Closure
Primary distribution channels typically close once components reach end-of-life, requiring alternative sourcing strategies.
Market Variability Risk
Secondary markets introduce variability in traceability, storage history, and handling conditions.
Inspection Criticality
Inspection depth becomes essential because in obsolete sourcing, the cost of a failed lot exceeds the cost of the component.
Supplier Qualification & Performance Governance
Structured Supplier Admission
Supplier participation is restricted and subject to formal qualification including documentation verification, capability assessment, and quality system review.
Performance Evaluation
Supplier performance is continuously evaluated using inspection outcomes, documentation integrity, and delivery reliability metrics.
Governance-Based Sourcing
Inspection history and transaction performance directly influence future sourcing allocation decisions and escalation testing depth.
In-House Inspection Workflow
Receiving & Documentation Review
Incoming lots are verified for packaging integrity, label and date-code consistency, part number accuracy, quantity confirmation, and ESD handling compliance. Documentation is cross-checked prior to inspection.
Digital Visual Inspection (30x–100x)
All units undergo DVI to detect resurfacing, remarking, oxidation, lead reconditioning, surface irregularities, and marking or font inconsistencies. Any anomaly triggers escalation.
Risk-Based Escalation Testing
When risk indicators are detected, advanced testing such as XRF analysis, X-ray imaging, decapsulation, die verification, and electrical testing is conducted through accredited third-party laboratories aligned with AS6081, AS6171, and ISO/IEC 17025.
Counterfeit Mitigation Protocol
Counterfeit risk is addressed through a structured, multi-layer authentication process.
100% Digital Visual Inspection (DVI) on received units.
Packaging, marking, and date-code consistency verification.
AQL-defined sampling based on lot size and risk classification.
Where risk indicators are identified, escalation testing is initiated through accredited third-party laboratories aligned with AS6171 and ISO/IEC 17025 standards.
Authentication depth scales based on supplier performance history, part criticality, and application sensitivity.
Shipment release is contingent upon inspection outcome.

Representative Inspection Evidence
Digital Visual Inspection (30-100x)
Detection of resurfacing patterns and lead reconditioning indicators.
X-Ray Imaging
Internal structure verification and bond wire alignment analysis.
Decapsulation & Die Verification
Die marking confirmation and manufacturer consistency validation.
Coplanarity & Lead Integrity Check
Measurement of lead alignment and planarity to identify reconditioning or mechanical stress.
Acetone Test & Marking Resistance
Surface marking verification to detect remarking or print alteration.
Key Functional / Electrical Testing
Basic functional validation where required to confirm operational behavior prior to release.
