摘要:
针对传统染料类整平剂通孔镀整平能力较差的问题，在酸性催化条件下合成了简单高效的4-苯基咪唑基季铵盐整平剂，并利用核磁氢谱、红外光谱、飞行时间质谱对其结构进行表征。采用电化学循环伏安法、计时电位分析法、哈林槽电镀性能测试、金相切片观察法等一系列手段对其整平性能展开研究。结果表明：4-苯基咪唑基季铵盐整平剂具有极高的整平能力，在温度25 ℃，电流密度1.6 ASD条件下采用哈林槽进行60 min电镀实验测试，仅4 mg/L浓度的整平剂便能够显著提高通孔镀的深镀能力(TP)值至93.33%．
Abstract:
The objective of this study was to address the issue of inadequate levelling capabilities exhibited by conventional dye-based levelling agents in through-hole plating. To this end, a straightforward and effective 4-phenylimidazolyl quaternary ammonium salt levelling agent was synthesized under acid-catalytic conditions. The structural characteristics of this agent were then elucidated through the utilisation of nuclear magnetic resonance (NMR) hydrogen spectroscopy, infrared spectroscopy and time-of-flight mass spectrometry. The levelling performance was investigated through a series of methods, including electrochemical cyclic voltammetry, chrono-potential analysis, Hall bath plating performance testing and metallographic section observation. The findings demonstrate that the 4-phenylimidazole-based levelling agent exhibits an exceptionally high levelling capacity. A mere 4 mg/L concentration of the agent was observed to markedly enhance the throwing power (TP) value of through-hole plating by 93.33% in a Hall bath plating experiment conducted for 60 minutes at a temperature of 25 °C and a current density of 1.6 ASD
