摘要
介绍了酸性镀铜光亮剂 ,并与使用较多的两种国外酸铜光亮剂的阴极极化曲线、镀液的深镀能力、均镀能力、耐温工作范围等作了对比。酸铜光亮剂耐高温可达 40℃ ,其深镀能力、均镀能力与国外酸铜光亮剂相当。其阴极极化曲线也与国外酸铜光亮剂的阴极极化曲线形状相似 ,峰值电位和峰值电流相近 ,极化值与极化度近于相等。
A brightener for acidic copper plating had been presented. Cathodic polarization curve, covering power, throwing power and operation temperature range of the brightener had been tested and had been compared with those of two kinds of abroad brightener. The cathodic polarization curve of the brightener is similar to those of the abroad ones'. Covering power, throwing power, polarization value, polarizability, peak point potential and peak point current of the brightener are also almost equal to those of the abroad counterparts.
