LED plating uses stamped LED brackets made of copper alloy, iron-nickel alloy, aluminum and other materials as substrates. Multiple metal coatings are electrolytically deposited to realize five core functions: light reflection, electrical conduction, heat dissipation, die bonding & wire bonding, anti-oxidation and anti-corrosion. This process directly determines the brightness, light decay, service life and soldering reliability of LEDs.
Silver plating systems are the mainstream in the industry, while nickel-palladium-gold composite coatings are adopted for high-end automotive-grade and high-power LEDs.
