COMPONENT HAVING ELECTRODE DISSOLUTION PREVENTION LAYER, AND MANUFACTURING METHOD THEREFOR |
摘要 |
Provided is a method for manufacturing a component having an electrode corrosion preventing layer by performing the low-cost, high-yield and highly reliable soldering, can be provided. The method for manufacturing a component includes: a step of preparing component 10' having electrode 2; a step of contacting first organic fatty acid-containing solution 3a with electrode 2; a step of adhering first molten solder 5a onto electrode 2 by contacting first molten solder 5a with electrode 2; a step of ejecting a gas flow or a liquid flow to adhered first molten solder 5a to remove excess first molten solder 5a in first molten solder 5a adhered onto electrode 2; and a step of cooling electrode 2 from which excess first molten solder 5a has been removed to less than a melting point of first molten solder 5a. First molten solder 5a includes a component forming electrode corrosion preventing layer 4 made of an intermetallic compound layer on a surface of electrode 2 by reacting with a component included in electrode 2, and the contact of first molten solder 5a with electrode 2 is performed by allowing a liquid flow of first molten solder 5a to collide with or spread over electrode 2while moving component 10'. |
