Electronic scrap


Electronic scrap is an especially fertile source of value. The value is not always obvious, because small quantities of precious metals are typically hidden in large quantities of base metals, plastics and ceramics.

It makes sense to save defective or obsolete electronic components. There’s gold and silver in those relays and contact points, pc boards, semi-conductors, transformers and diodes, grid wires, anodes and wave guides. Platinum group metals are hidden in thermocouples, tube grids, switches and igniters.

And that’s only the beginning. Any or all precious metals may turn up in connectors, sealed headers, lead frames, integrated circuits, slip ring assemblies, laminates, batteries, capacitors, resistors and transistors.

The percentage of precious metals in electronic scrap may be very small. But its value may be very high. Capacitor and resistor production rejects. Their leads contain gold.

Ceramic substrates bear platinum, palladium and ruthenium.

Solder salvaged from pc board soldering operations. The solder is tin, lead, and gold. Miscellaneous electronic scrap (containing precious metals). Batteries salvaged from digital watches and hearing aids. Their power source? Silver oxide.
Pin boards recovered from obsolete computers. Blanking scrap - gold on beryllium copper. The gold plating on the pins is never obsolete.
