Gold-Plated E-Waste Edge Connectors/RAM Fingers
Electronic Scrap / Precious Metal Reclamation Material · Generic Electronic Component Manufacturers (e.g., Intel, Micron, Samsung)
Pattern: Standard Industrial PPCB (Printed Circuit Board) Edge Connector Fingers
Type
Electronic Scrap / Precious Metal Reclamation Material
Maker
Generic Electronic Component Manufacturers (e.g., Intel, Micron, Samsung)
Material
Hard Gold Plating (typically 99.7% gold/0.3% cobalt) over Nickel and Copper base layers
Dimensions
Standard RAM/Expansion Card width (approx 0.5 - 1.0 inches length); estimated total weight in bag is 100-200 grams
Description
A collection of gold-plated 'fingers' harvested from scrap Random Access Memory (RAM) modules and expansion cards. These strips are prized for their gold content and are a staple of the precious metal refining industry.
Key Features
High-purity gold plating on flat copper-nickel fingers; distinct parallel rectangular contacts; uniform industrial finish
Material & Composition
Hard Gold Plating (typically 99.7% gold/0.3% cobalt) over Nickel and Copper base layers
Finish & Decoration
Industrial Electrolytic Plating; functional parallel contact surfaces for electrical conductivity
Hallmarks & Stamps
None; industrial components typically lack purity stamps; markings may exist on the original PPCB substrate
Construction Details
Machine-cut from larger Printed Circuit Boards; involves fiberglass (FR4) substrate removal
Functional Features
Low-resistance electrical contact points designed for high-frequency data transmission and corrosion resistance
Handle & Grip Details
N/A; Small industrial strips with serrated edges from mechanical cutting
Craftsmanship Details
Precision industrial mass production featuring high-speed electrolytic plating and automated mechanical shearing
Authentication Indicators
Visual identification of standard PPCB trace patterns; typical yellowish hue of industrial hard gold plating; lack of artisan hallmarks
Origin & Manufacturing
Global industrial electronic manufacturing hubs (China, Taiwan, South Korea, USA)
Era & Period
Modern Computing Age (c. 1990 - Present)
Age Estimate
Late 20th to early 21st Century (likely mid-2000s computing hardware)
Cultural Significance
Represents the 'Urban Mining' movement and the global effort to recover precious metals from electronic waste (e-waste)
Condition Notes
Scrap condition; mechanically sheared from boards, containing fiberglass dust and adhesive residue; tarnished base metals on edges
Value Estimate
$50 - $120 per pound depending on current gold spot price and purity of the specific batch
Care & Maintenance
Store in a chemical-resistant bag; avoid skin contact if fiberglass dust is present; refine only with proper safety equipment and legal permits
