Purity
24K / 999.9 Gold Content (Bond Wires)
Gold Type
Yellow Gold (Pure Industrial Bond Wires)
Weight
Trace amount (Micrograms of gold per unit)
Description
This is a 5050 SMD (Surface Mount Device) LED component, typically found in LED strips. While primarily an electronic part, it contains high-purity gold in the form of 'bond wires'—microscopic threads that connect the semiconductor die to the lead frame. In the world of precious metal recovery (e-waste scrapping), these items are collected for the refinement of the 24K gold contained within.
Key Features
Visible internal gold-colored bond wires under the silicone lens; six lateral solder leads for electrical connection.
Color & Finish
The gold bond wires exhibit a high-purity yellow gold luster; the housing is white polymer/silicone.
Hallmarks & Stamps
None (Industrial manufacturer batch codes usually present on original reel)
Dimensions Estimate
Approximately 5mm x 5mm (Standard 5050 SMD package)
Gemstones & Inlays
No gemstones; contains a semiconductor light-emitting diode chip and microscopic gold wires.
Clasp & Closure
Solder pads (6-lead configuration for electrical mounting)
Chain & Links
Not applicable (Rigid semiconductor package)
Craftsmanship Details
Precision automated assembly; ultrasonic wire bonding used to attach the micron-thin gold wires.
Authentication Indicators
Characteristic yellow luster of 5n (99.999% purity) gold wires used in precision electronics to prevent corrosion.
Origin & Maker
Generic electronic component manufacturer (likely Southeast Asia/China)
Era & Period
Contemporary (Technological Era, 2010s-present)
Age Estimate
Modern production (Last 5-10 years)
Cultural Significance
Represents the 'Urban Mining' movement where gold is reclaimed from obsolete technology rather than traditional mines.
Condition Notes
Used/Scrap (Shows evidence of desoldering or mechanical removal from a PCB).
Value Estimate
Negligible as a single unit ($0.0001 range); significant value only when accumulated in multi-kilogram quantities for industrial refining.
Care & Maintenance
Store in a static-safe container if intended for use; store in a refinement bin if intended for gold recovery.

Interesting Facts
Gold is used in electronics not for its value, but because it is an excellent conductor and does not tarnish or rust, ensuring long-term reliability of the electrical connection.
