| titleOfInvention | Copper surface treatment solution, copper surface treatment method using the same, and method for manufacturing printed wiring board |
| abstract | (57) [Summary] [Problem] To be able to use formaldehyde as a reducing agent in a stable state for a long time, to improve the working efficiency, and to suppress the amount of highly dangerous formaldehyde discharged outside the factory. Provided are a copper surface treatment solution, a copper surface treatment method using the same, and a method for producing a printed wiring board. A copper surface treatment solution containing formaldehyde and tetraboric acid or a salt thereof. And a. Contacting the copper surface with an aqueous solution containing an oxidizing agent to form copper oxide on the copper surface; b. Reducing the oxidized copper surface by contacting the oxidized copper surface with an aqueous solution containing alkali borohydride; c. A copper surface treatment method for reducing copper oxide formed on the copper surface by the step of further reducing the copper surface by contacting with a copper surface treatment solution containing formaldehyde and tetraboric acid or a salt thereof, And a method of manufacturing a printed wiring board. |
