Industrial Yellow Gold (99.9% pure) used for high-conductivity plating and wire-bonding
Weight
Trace Amounts: Roughly 2-5 micrograms of gold per individual LED unit
Description
An industrial electronic assembly featuring Surface Mount Device (SMD) Light Emitting Diodes (LEDs). While primarily a technical component, these items contain high-purity 'four-nines' (99.99%) gold wire used to connect the semiconductor chip to the leadframe. The gold ensures maximum electrical conductivity and prevents oxidation in the high-heat environment of the LED light source.
Key Features
High-purity gold wire bonding and gold-plated copper leadframes for superior corrosion resistance and signal integrity in solid-state electronics.
Color & Finish
Vivid Golden-Yellow visible through phosphor coating; metallic silver-gold luster on lead terminals with a matte-to-satin industrial finish
Hallmarks & Stamps
No purity hallmarks; identification via manufacturer internal batch codes and electronic part numbers (typically SMD 2835 or 5730 packaging)
Dimensions Estimate
Each LED unit measures approximately 2.8mm x 3.5mm; internal gold wires are typically 25 microns in diameter
Gemstones & Inlays
None; yellow appearance is derived from a YAG (Yttrium Aluminum Garnet) phosphor resin coating over an InGaN semiconductor chip
Clasp & Closure
Mechanical solder joints on the copper/alloy leadframe terminals to a Printed Circuit Board (PCB)
Chain & Links
N/A; internal structure consists of microscopic 'wire bonds' created via thermosonic ball bonding
Craftsmanship Details
Precision automated manufacturing; micro-robotic wire bonding; chemical vapor deposition for gold plating; high-tolerance resin molding.
Authentication Indicators
Identification based on electronic component morphology; gold presence confirmed via industrial specification sheets for SMD-type LED fabrication.
Origin & Maker
Mass-produced industrial electronics (e.g., Samsung, Epistar, Cree, or generic Pacific Rim manufacturers)
Era & Period
Contemporary Digital Era (2010s-Present); High-efficiency solid-state lighting period
Age Estimate
Circa 2015-2024; based on the standard SMD packaging and dual-die phosphor configuration
Cultural Significance
Represents the shift of gold from a symbol of wealth to a critical functional metal in the global transition toward energy-efficient technology.
Condition Notes
Functional Industrial Grade; surface show signs of resin encapsulation and typical manufacturing residue; the gold is protected within the housing.
Value Estimate
Negligible 'melt' value per unit (less than $0.01 USD); value is found only in bulk recycling of thousands of units where total gold recovery becomes commercially viable.
Care & Maintenance
Keep away from moisture to prevent electrolytic corrosion of the non-gold base metals; require industrial recycling (Urban Mining) to recover gold content.

Interesting Facts
The electronics industry is the third largest consumer of gold globally. LED technology relies on gold's unique ductility to create wires thinner than a human hair that can withstand thousands of thermal cycles.
