The invention relates to a method for electroplating an LED pin with a high-gloss silver coating. The method comprises the following steps: 1, adding the LED pin; 2, carrying out thermal degreasing and electric degreasing of the surface of the pin by sodium carbonate; 3, carrying out acid activation; 4, electroplating copper; 4, electroplating silver; and 6, carrying out cleaning, drying and protection treatment of the obtained coating, wherein the acid activation adopts a mixed solution containing 40-80g/L of hydrofluoric acid and 5-15g/L of sulfuric acid; the copper plating is two-step copper plating and comprises cyanide copper plating and copper sulfate plating; and the above silver plating technology is characterized in that materials used in the silver plating comprise 20-50g/L of silver nitrate, 140-200g/L of hydantoin, 30-70g/L of potash, 5-15g/L of boric acid, 120-140g/L of potassium citrate and 10-15mL of a brightener, silver plating is carried out at 20-100DEG C, the cathode current density is 0.1-2A/dm<2>, and a 99.99% pure silver plate is used as an anode. The method enables the gloss of the obtained coating to reach 1.7-1.8 in case and the extremely-thin silver coating (1mum) to be guaranteed, so demands of the subsequent welding quality and the conductive performance can be fully satisfied.
