Embodiment 1

[0055] Embodiment 1 discloses an electroplating process that can improve efficiency. The moving direction of the workpiece is the same as the length direction of the electroplating tank. The length of each tank is 1 meter, and the casting speed is 21.5 m / min. Above-mentioned a kind of electroplating process that can improve efficiency comprises the following steps:

[0056] 1. Hot water washing: Put the workpiece into water heated to 50°C for hot cleaning. After thermal cleaning, put the workpiece into water with a pH of 7.5 for washing. Wherein, the section number of the thermal cleaning tank is 1, and the section number of the water washing tank is 3.

[0057] 2. Degreasing: put the workpiece into the degreasing liquid, and power on for degreasing. The degreasing liquid includes degreasing powder with a concentration of 60g / L, and the Baume degree of the degreasing liquid is 8°Bé. The current is 25A and the temperature is 55°C. After degreasing, put the workpiece into wa...

[0071] Embodiment 2-6 discloses a kind of electroplating process that can improve efficiency, and its steps are identical with embodiment 1, and the cell number, electric current, pulling speed of the tank (not including washing tank) of each step are shown in the table below.

[0072] The node number of the groove of each step in embodiment 1-6

[0073]

[0074] Electric current (A), pulling speed (m / min) of each step in embodiment 1-6

[0075]

[0076] Among them, Embodiments 3-6 also disclose an electroplating tank, which is used in the steps of alkali copper plating, acid copper plating, nickel plating, pre-silver plating and silver plating. refer to figure 1 , the electroplating tank includes a mother groove 1 and a sub-groove 2 located in the mother groove 1, and a conductive seat 3 for conducting electricity is provided in the sub-groove 2, and the workpiece 4 passes through the mother groove 1 and the sub-groove 2, and is in contact with the conductive seat 3 ....

Embodiment 7

[0087] Embodiment 7 discloses an electroplating process that can improve efficiency. The difference from Embodiment 4 is that the total width of the conductive sheet 32 ​​and the conductive plate 7 is 25 mm.

Abstract

The invention particularly discloses an electroplating process capable of improving efficiency and an electroplating bath. The electroplating process capable of improving the efficiency comprises thefollowing steps of hot water washing, oil removal, activation, alkaline copper plating, acid copper plating, nickel plating, cyanogen electrolysis, silver pre-plating, silver plating, silver stripping, electrolytic cleaning, oxidation prevention, ultrasonic water washing and drying, wherein the pulling speed is 18-25 m / min, the total length of one side of the electroplating bath for alkaline copper plating, acid copper plating, nickel plating, silver pre-plating and silver plating in the moving direction of a workpiece is 37-44 m, the current of alkaline copper plating is greater than 12 A, the current of acid copper plating is greater than 8 A, the current of nickel plating is greater than 22 A, the current of silver pre-plating is greater than 5 A, the current of silver plating is greater than 3 A, and the yield of the workpiece is 98.5% or above. The electroplating process capable of improving the efficiency has the beneficial effects that the filling and leveling effect of the workpiece is guaranteed, the electroplating efficiency is improved, the capacity is increased, the energy utilization rate of the process and equipment can be effectively increased, and the energy-savingeffect is achieved.

Description

technical field [0001] The application relates to the field of surface treatment, more specifically, it relates to an electroplating process and an electroplating tank that can improve efficiency. Background technique [0002] Due to the advantages of small size, low power and long service life of LED, the application of LED is more and more extensive. The application of LED includes LED backlight, LED lighting, LED display and so on. [0003] The production process of LED products includes multiple processing techniques, and electroplating is one of the important processing links. Electroplating is the process of placing the workpiece in an electroplating tank filled with electroplating solution, and conducting a current on the workpiece, using electrolysis to coat a layer of metal on the surface of the workpiece, so that a layer of film is attached to the surface of the workpiece, basically including Washing, degreasing, acid copper plating and other steps. Electroplatin...
