WHO WE SERVE

Where the metal hides

Plating, board and assembly lines send precious metal out with their waste. We look for it in lead frames, rinse water and spent baths.

SEMICONDUCTOR

Where semiconductor assembly loses precious metal

A lead frame strip, before it is trimmed into individual packages.

Assembly and test lines run lead frames and finished packages past you every day. The gold sits as a thin plated layer on the leads and bond pads, not as bulk metal, so it never looks like much on its own.

It can be missed because reject trays and package waste may be priced as scrap copper, or binned, without the precious layer being weighed separately.

The first step is a tray. Send us your rejected lead frames or IC packages, we check them, and you get a number back.

PRINTED CIRCUIT BOARDS

What a board line throws away without weighing it

Board fragments and rejected packages, sorted for assay.

A board line produces etchant, rinse water and offcuts or rejected boards. Gold sits on the connector fingers and electroless nickel immersion gold (ENIG) pads, and copper runs through the whole board.

Waste disposal is priced by what it costs to remove, not by what the waste holds. The rinse water is worth testing for the metal it carries.

Send us a sample of the rinse water and a handful of board fragments. We test both and tell you whether either is worth collecting properly.

ELECTROPLATING

What a spent bath is still worth

Metal dross, the kind collected when a bath or tank is cleaned out.

Plating and surface finishing lines run baths that carry gold or silver, depending on what they are finishing. Rinse tanks pick up more of it, and dross collects wherever a bath is filtered or a tank is cleaned out.

A bath is run and topped up as a routine cost. When it is retired, it is handled as waste and priced by disposal cost, not by what is dissolved in it.

Send us a sample of the spent bath or a scoop of the dross. We check it and tell you what it is worth.

JEWELLERY AND PRECIOUS METALS

What is sitting in your sweeps and dross

Metal filings and sweepings collected in a small dish for assay Illustration

Bench sweepings, the kind that collect in a drawer for years.

Workshops generate bench sweeps off the floor and bench, polishing dust caught in the extraction filter, casting dross, and worn-out or broken findings.

Small amounts get swept into a bag and left in a drawer, because nobody has assayed them, or they get sold to a buyer who quotes by eye rather than a measured reading.

Send us a sample. We assay it and tell you what it holds.
