Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plating apparatus capable of removing whiskers generated by tin plating by electrodeposition and a plating method using the plating apparatus,

The present invention relates to a plating apparatus for plating tin on copper and a plating method using the plating apparatus. More particularly, the present invention relates to a plating apparatus for plating copper on tin and then effectively removing whiskers through electrodeposition to improve plating quality, The present invention relates to a plating apparatus capable of removing whiskers generated by tin plating by electrodeposition which can produce a high quality plating product by performing an electroplating process and a plating method using the same.

Generally, in plating a metal plate, plating is performed by immersing a product to be plated in a plating bath and bringing the product into contact with the plating solution.

In this case, plating is performed through a chemical reaction. If plating is performed only by a chemical reaction, whiskers are generated during the chemical reaction, so that the plating surface is not smooth, and accordingly, a separate surface treatment process for smoothing the plating surface is required.

The surface treatment process mainly uses a heat treatment method. Conventionally, since the surface treatment is performed by heating the outside by providing a heating furnace on the outer side of the plate material, the temperature of the heat treatment can not be finely controlled. There arises a problem that the plating is not finely plated on the side of the plate to be plated.

In order to solve the above problem, in the prior art 1 (reflow equipment and method for tin plating process of metal plate), induction heating is applied to heat both sides of a plate, And the plating quality can be increased according to the through-flow.

However, in the prior art document 1, high-frequency heating is performed on both sides of the metal sheet when passing the high frequency through the metal sheet, so that the outside of the metal sheet is heated first, and then the outside is melted and flowed down.

In addition, since a separate flattening operation is not performed, only a reflow effect by high-frequency heating can be expected, and the plating quality is lowered due to cooling immediately after the plating surface is not uniform due to melting.
