for gold recovery
what parts of the led or LCD tv are composed of gold
Gold is used in small amounts within LED and LCD televisions, primarily for its excellent conductivity and resistance to corrosion on critical connectors. While modern, thinner televisions often contain less gold than older models, several components still contain recoverable gold.
The primary components that contain gold include:
Finger Strip Boards (COG - Chip on Glass): These are thin, long boards located along the top or side of the LCD screen, which connect to the main display panel. They are known for having gold-plated "fingers".
TCON (Timing Controller) Board: The ribbon cables and contacts connected to the TCON board are often gold-plated.
Printed Circuit Boards (PCBs):
Main Board: Contains various Integrated Circuit (IC) chips,, pin connectors, and sometimes gold-plated traces.
Control Boards: Often contain gold-plated pins in plugs and, in some cases, on the surface of the boards.
Internal Connectors and Pins: Connector pins, sockets, and ribbon cables often have gold-plated contacts.
IC Chips and Transistors: Many chips, including Ball Grid Array (BGA) chips (especially "gold corner" BGA chips) and some smaller transistors, have gold-plated bonding wires inside.
LED Backlight Strips: Specific to LED TVs, the LED backlights themselves may contain gold-plated dots or microscopic gold bonding wires.
Component Parts: Certain capacitors, resistors, and ceramic fuses, especially on the TCON board, can contain trace amounts of gold.
On average, a standard flat-screen TV contains about
