Abstract

The invention discloses a method for acidic copper plating of hardware. The copper plating comprises of, by mass, 250g / L of copper sulfate, 70g / L of sulfuric acid, and 35mg / L of chloride ion; the copper plating comprises of, by concentration volume, 7.5ml / L of BFJ-210M[um], 0.8ml / L of BFJ-210A, and 0.8ml / L of BFJ-210B; and the copper plating comprises of, by electric current density, 6A / dm<2> of cathode, and 5A / dm<2> of anode. Plating solution is prepared and the method includes the steps that 1, 1 / 2 volume of distilled water is added to a cylinder to be used; 2, the calculated amount of copper sulfate is added to the cylinder to be used; 3, activated carbon solution is added to the cylinder to be used, and the solution concentration is 2g / L; and 4, the calculated amount of sulfuric acid is added to a plating bath. The method for the acidic copper plating of the hardware realizes rapid brightening and has excellent filling degree, and high filling degree can be obtained even in the lowelectric current density region; and the deposition speed is high, at 4.5 amperes per square decimeter of the electric current density, a 1 micron copper layer can be plated per minute, and thereforethe plating time is shortened, thereby greatly increasing the copper plating speed of the hardware.

Description

technical field [0001] The invention relates to the technical field of copper plating equipment, in particular to a method for acid copper plating of hardware. Background technique [0002] The acid copper plating process is suitable for the intermediate plating layer as a decorative plating layer, used for plating various lighting, hardware tools and daily necessities, and is also widely used in plastic plating, PCB plating and electroforming. The traditional copper plating solution tends to cause potholes on the surface of the hardware during the copper plating process, and the solution deposition rate is slow, which reduces the copper plating efficiency. Contents of the invention [0003] The object of the present invention is to provide a method for acidic copper plating of hardware to solve existing technical defects and technical requirements that cannot be met. [0004] In order to achieve the above object, the present invention provides the following technical sol...
