100+g Trimmed Gold-Plated PCB Edge Connector Fingers - 1990s Telecom and Electronics Scrap for Precious Metal Recovery
Condition
Single lot available. Weighed at 100+g on an Ohaus LS 200 scale - photos show the actual scale reading. Fingers are trimmed edge connector strips cut from 1990s-era telecom boards and older electronics. Photos show the specific pieces you will receive. Contacts show oxidation and surface patina consistent with age; green fiberglass PCB substrate remnants visible on many strips. Mix of widths and pin counts. No returns on scrap purchases - what you see in the photos is what ships.
Carefully packed and shipped same business day from our Idaho warehouse. Online since 1999. Honest equipment and straightforward service.
No hassle resolution if there is an issue. Serving customers since 1999.
Product Overview
Gold-plated PCB edge connector fingers, trimmed from circuit boards originating in 1990s telecom equipment and older electronics. Older telecom-grade hardware is known for denser gold plating due to the reliability demands of that era. These are sold strictly as raw material for precious metal recovery - not as functional components.
Key Features
- Confirmed weight: 100+g (verified on Ohaus LS 200 scale - photos document the reading)
- Source: 1990s telecom equipment and older vintage electronics
- Trimmed edge connector strips - minimal excess PCB substrate on most pieces
- Mixed lot: varied finger lengths, widths, and pin counts
- Gold-plated contacts - older telecom-grade boards associated with thicker electroplated hard gold
- Oxidation and surface patina visible - consistent with age, does not affect gold content
- Green fiberglass substrate remnants visible on several strips
- Sold as-is for precious metal recovery - no functional use
Applications
- Hobbyist and small-scale gold refining via aqua regia or chemical leaching
- Electrolytic gold recovery
- E-scrap precious metal reclamation
- Feed material for professional gold refineries
- Urban gold mining and e-waste recycling projects
Frequently Asked Questions
What is the confirmed weight of this lot?
100+ grams, verified on an Ohaus LS 200 scale. The scale reading is visible in the product photos.
Are these double-sided fingers or single-sided?
The lot is mixed. Photos show both single and double-sided strips. Examine the photos to assess the mix before purchasing.
What is the gold content or expected yield?
Not confirmed. Actual gold yield depends on plating thickness, refining method, and process efficiency. Older telecom-grade boards are generally associated with thicker gold plating, but yield can only be determined by assay or XRF analysis. Estimate accordingly.
Are returns accepted?
No. Scrap purchases are final. The photos show the exact lot you will receive - examine them carefully before purchasing.
What refining method works for these?
Common approaches include aqua regia dissolution, copper chloride chemical leaching, and electrolytic recovery. Method selection depends on your setup, scale, and experience. This lot makes no claims about refining suitability for any specific process.
Somewhere in the 1990s, these contacts were doing serious work inside telecom racks that ran 24 hours a day. Now the boards are gone and the gold is still here - ready for whoever has the chemistry and the patience to bring it back out.
