| Applications |
1. SP serves as grain refiner in acid copper baths.
2. SP will have distinct effects in conjunction with M, N, PN, GISS or AESS.
3. Too low concentration of SP in baths will course the loss of brightness and HCD roughness and burning; Too high
concentration of SP in baths will result to hazy plating layer, and it may have negative effects on LCD area. This could be
solved by adding a small amount of N or by electrolysis |
