METHOD FOR MANUFACTURING THIN PLATE HAVING HEATING AND AMORPHOUS CHARACTERISTICS THROUGH PLATING

摘要

The present invention relates to a low-temperature bonding method for a low-temperature bonding brazing alloy. The present invention comprises a low-temperature bonding method for a low-temperature bonding brazing alloy. In addition, the present invention comprises a method for manufacturing a thin plate through plating, the method comprising: a step of preparing a water-based alloy plating solution comprising at least two metallic salts including a first metallic salt and a second metallic sa an electrode preparation step for preparing an anode and a cathode, the cathode being selected from among metals forming passive films and being prepared by attaching a peeling assist tape having a resistance against to acid or alkali; a step of configuring an electroplating circuit by immersing the anode and the cathode into the water-based alloy plating solution; a step of applying a reduction potential or current to the anode or the cathode by inputting, to a control unit for controlling the electroplating circuit, the value of a voltage between +2 V and -4.5 V or a current corresponding thereto on the basis of a 25°C standard hydrogen electrode according to the value of the reduction potential of the metallic salts to be plated; a step of forming at least two multilayered amorphous metallic plating films on the cathode due to the standard reduction potential difference between the metallic salts; and a step of obtaining a thin plate by removing the peeling assist tape from the cathode and separating the at least two multilayered amorphous metallic plating films, followed by washing and drying. The present invention enables a low-temperature process by replacing foil, filler, powder and paste used in brazing. Therefore, it is possible to reduce substrate damage or defects a due to heat generated from brazing, and there is an effect of contributing to energy saving because the process is performed at low temperatures.
