Embodiment 1
[0010] A kind of technique of ultrasonic electroplating copper foil, its steps are as follows: 1, preparation electroplating solution, by 65g / L stannous chloride, 100ml / L sulfuric acid, 5g / L sodium ethylene sulfonate, 3g / L butynediol, 2g Ascorbic acid, 5g / L cerium carbonate, and the balance is distilled water to formulate the electroplating solution, and adjust the pH to 3 with ammonia water. 2. Pre-plating treatment, the copper foil 4 moves through the cleaning tank 1 at a speed of 10m / h, and is cleaned with deionized water in the cleaning tank 1, and 20KHz ultrasonic waves are added during cleaning, and the surface of the copper foil 4 is removed by ultrasonic cleaning with deionized water grease and impurities. 3. After the pre-plating treatment is completed, the copper foil 4 continues to move forward at a speed of 10m / h, and enters the tin plating tank 2 filled with electroplating solution through the pulley 5. The copper foil 4 is connected to the cathode of the DC power...
