Product Overview
Trimmed printed circuit board edge connectors featuring gold-plated contact fingers on FR-4 substrate. Cut from assorted legacy computer memory modules and expansion bus cards. Sourced for precious metal recovery, hydrometallurgical refining, assay study, and small-batch chemical leaching processes.
Key Features
- Gold-plated contact fingers over copper trace on rigid circuit board substrate.
- Assorted contact styles including standard expansion bus and memory card contact pitches.
- Trimmed close to the contact area to minimize excess substrate material.
- Total lot weight corresponds to the 102-gram label designation.
Applications
- Recovering contact plating in chemical refining processes using acid-peroxide or aqua regia baths.
- Benchtop precious metals reclamation experiments and hydrometallurgical process testing.
- Educational demonstrations of gold precipitation and electro-refining techniques.
Frequently Asked Questions
What substrate material are these fingers on?
The contacts are on rigid green and brown printed circuit board material, typically fiberglass-reinforced epoxy (FR-4).
Are these fingers tested for gold yield or thickness?
No assay, thickness measurement, or chemical yield testing has been performed on this scrap material.
What condition is this scrap and what am I taking on?
This is untraced circuit board scrap sold as-is for reclamation. Photos are of the actual stock, and the buyer assumes all processing, refining, assay, and recovery risks.
Pound for pound, old expansion slots and memory sticks carried real plating to keep high-frequency signals clean across copper traces. Now it is up to the refiner to bring that shine back into the crucible.
