Gold Bonding Wire and Plating in SMD LED Linear Strip
Raw Gold / Industrial Electronic Component · Yellow Gold (Industrial Fine Gold)
Purity: 99.99% (24K) pure gold bonding wire; likely 10-50 micro-inches of gold plating on contact pads
Type
Raw Gold / Industrial Electronic Component
Purity
99.99% (24K) pure gold bonding wire; likely 10-50 micro-inches of gold plating on contact pads
Gold Type
Yellow Gold (Industrial Fine Gold)
Weight
Negligible per unit (approximately 0.001g to 0.005g of recoverable gold per linear meter of high-density strip)
Description
This is a linear LED (Light Emitting Diode) lighting component, not a piece of jewelry. It contains microscopic quantities of high-purity gold used for 'bonding wires' that connect the semiconductor chip to the lead frame. Gold is prized in these electronics for its superior conductivity and resistance to oxidation, ensuring the light remains functional over thousands of hours.
Key Features
Microscopic 24K gold bonding wires; gold-plated contact pads for corrosion-resistant soldering; high-density SMD arrangement on a white reflective substrate
Color & Finish
Vivid yellow metallic bonding wires visible under magnification; matte white housing with gold-tone solder pads
Hallmarks & Stamps
None (Industrial components utilize batch codes or manufacturer logos printed on the PCB reverse, typically not hallmarked)
Dimensions Estimate
Standard 8mm or 10mm wide PCB strip; LED chips approximately 2.8mm x 3.5mm (2835 SMD) or 5.0mm x 5.0mm (5050 SMD)
Gemstones & Inlays
No gemstones; functional phosphor coating over gallium-nitride semiconductor dies
Clasp & Closure
Not applicable; typically features an adhesive backing (3M tape) or friction-fit connectors
Chain & Links
Not applicable; parallel/series circuit trace construction on a flexible or rigid copper-clad laminate PCB
Craftsmanship Details
High-precision automated robotic wire-bonding and surface-mount technology (SMT) assembly; clean-room manufacturing standards
Authentication Indicators
The bright yellow glint within the encapsulate is characteristic of 99.99% pure gold bonding wire used in semi-conductor packaging
Origin & Maker
Likely East Asian manufacturing (China, Taiwan, or South Korea); typical of brands like Samsung, Osram, or generic industrial suppliers
Era & Period
Contemporary High-Tech Era (Post-2010)
Age Estimate
Circa 2015-2024, based on the SMD (Surface Mount Device) architecture and high-density chip placement
Cultural Significance
Represents the 'Electronic Gold' movement—the transition of gold's value from purely decorative or monetary to an essential component of the digital and green-energy age
Condition Notes
Appears to be in New/Unused condition; no thermal degradation or solder marks visible on the exposed chip faces; Excellent structural integrity
Value Estimate
Melt value is effectively zero for individual units; value is derived entirely from functional utility as a lighting component (~$5-$20 per meter retail). Requires mass industrial refining (tons of material) to recover significant gold value
Care & Maintenance
Keep away from moisture and static discharge (ESD). If cleaning is required, use 99% isopropyl alcohol and a lint-free swab; do not use jewelry cleaners
