• Inspect packaging: Original vs reopened

Electrical Testing

• Continuity test: Basic connectivity
• Functionality test: Using test equipment
• Parametric test: Electrical characteristics

Advanced Testing

• X-ray inspection: Internal structure
• Decapsulation: Die inspection
• Thermal testing: Performance under load

Testing Equipment

1. Multimeter: Basic continuity and voltage
2. Oscilloscope: Signal analysis
3. Logic analyzer: Digital circuit testing
4. IC tester: Specialized test equipment
5. X-ray machine: Internal inspection

Maximizing Value Through Testing

• Document test results: Proof of functionality
• Test before selling: Identify defective parts
• Separate by condition: Tested vs untested
• Provide test reports: Builds buyer confidence
