属の中においても半田付が可能な稀少価値の高い部類に
属する。Nickel plating generally has excellent color fastness, so it is not only used for decorative items, but also has high heat resistance, and is a rare and valuable class of high-melting point metals that can be soldered.

まう問題がある。However, because the surface of nickel-plated metal wire does not have a stable oxide film (which acts as a protective film), it may undergo abnormal oxidation and discoloration under harsh conditions, i.e., environments such as corrosive gases. There is a problem in that the value as an electronic component is reduced.

ならない必要がある。Conventionally, it is known that metal wires are coated with a higher fatty acid solution on the surface of tin-plated or solder-plated metal wires, but these have low heat resistance (melting point of tin is 231.8℃, and solder is Depending on the use of the plated wire (most of which are mixtures of lead and tin with a temperature below 450°C), it may be necessary to use nickel-plated wire or strip (the melting point of nickel is 1452°C).

．． A protective film is formed on the surface of the nickel-plated wires and strips using a solvent solution with a concentration of about 6 to 1.2, which maintains the gloss of the product and improves solderability. If the acid treatment according to the present invention is not performed, the discoloration will be large due to atmospheric oxidation or irritating gases, the solderability will be extremely poor when used as a component, and satisfactory soldering will not be possible unless a strong flux is used. could not.

法をとることができる。By the method of the present invention, it is possible to give nickel-plated wire excellent properties such as heat resistance and discoloration resistance that conventional tin and solder-plated metal wires do not have. The surface oxide film is thermally decomposed at 1°C (10 minutes) and does not have any adverse effect on the diode characteristics. Also,
By appropriately changing the concentration of the acid in the solvent solution, a method can be used to form a film by coating with an applicator and continuously passing through an acid bath.
