Discoloration inhibitor after reflow of tin-based alloy plating film |
| abstract |
Disclosed is an anti-discoloration agent that can be industrially put into practical use and can prevent discoloration that occurs after reflow of a tin-based alloy plating film. An anti-discoloration agent after reflow of a tin-based alloy plating film comprising phosphoric acid and optionally adding glycol ether to an aqueous solution containing an organic sulfonic acid. By immersing the tin-based alloy plating film in the above anti-discoloring agent bath, washing it with water and drying it, it is possible to obtain a plating film with good reflow characteristics and a plating film that does not cause discoloration after reflow. It becomes. [Selection figure] None |
