| titleOfInvention | Weak Acid Tin Plating Solution for Chip Plating |
| abstract | The present invention relates to a weakly acidic tin plating liquid for chip plating, and more particularly, the concentration of divalent tin ions in the tin plating liquid is 4 to 50 g / L; Free acid; Complexing agents; And a phenolethoxylate-based additive, an ampoalkoxypropionate-based additive, or a mixture thereof, and relates to a weakly acidic tin plating solution for chip plating, wherein the pH is adjusted to 3.5 to 5.0. According to the present invention, environmental pollution caused by lead eluted from tin-lead series solder can be prevented, and since it is a neutral to weakly acidic plating solution, there is little damage to chip components, excellent smoothness of plating film, and good solderability. Tin plating can be obtained. |
