【Abstract】 Based on the existing bath composition used for electroplating copper on copper substrate, an excellent copper electroplating bath composition for fabrication of printed circuit board（PCB） by modified full additive process was obtained using simplex optimization as follows: CuSO₄·5H₂O 71-84 g/L, H₂SO₄ 96-108 mL/L, Cl^- 44-65 mg/L, accelerant 0.5-0.9 mL/L, and wetting agent 13-20 mL/L. The result of verification test showed that the copper coating on aluminum plate obtained from the given electroplating bath is uniform and stable. The coefficient of variation（COV） of coating thickness is decreased to 2.71%-4.39%, which is favorable for the improvement of PCB products made by full additive method.更多还原
