Power Supply Boards
Switching power supply boards with copper and ferrite
Chemical Composition
Elemental breakdown by percentage weight.
Physical Properties
Material form, density, and contamination specifications.
Post-use power supply circuit boards; ubiquitous power conversion electronic component; LOW precious metal content; HIGH copper and base metal content (50-500g copper; 20-300g ferrite; 10-100g aluminum); ABSOLUTE HIGHEST supplier count commodity (412 suppliers; power supplies ubiquitous in ALL electronics); EXTREME volume-driven bulk commodity; copper-focused value recovery; hazmat complexity moderate (capacitors present; RoHS compliance variable); mass recycling commodity lowest-tier
- Copper windings 50-500g (power supply specification; highly variable acceptable)
- Ferrite core 20-300g (inert; acceptable)
- Aluminum 10-100g (valuable base metal; acceptable)
- Steel <50g (ferrous component; acceptable)
- Plastic 20-150g (inert substrate; acceptable)
- Silicon 5-50g (semiconductor; acceptable)
- Dust/corrosion typical (post-use acceptable)
- Solder <2g (minimal acceptable)
- Copper <50g per board (below power supply specification)
- Capacitors not removed (hazmat present; separation critical)
- Mercury components (hazmat extreme)
- Extreme contamination or degradation
Quality Assurance
Testing protocols, sampling methods, and acceptance criteria.
Required Test Methods
Spot Visual Power Rating Assessment
- Estimate power rating
- predict copper weight category
- confirm power supply type
- Power rating estimated (low/medium/high)
- copper weight range predicted
- Minimal spot inspection
- visual power rating assessment
- confirm power supply category
Capacitor Presence Visual Check
- Spot-verify capacitors typical presence
- confirm hazmat awareness
- Capacitors identified typical
- hazmat status known expected
- Sample visual inspection
- capacitor detection simple
- hazmat awareness confirmed
Bulk Commodity Classification
- Confirm bulk power supply commodity status
- cost-driven economics
- Commodity status confirmed
- bulk copper economics established
- Minimal classification
- commodity category confirmed
- bulk economics applicable
