摘 要:采用浸漬法以緩蝕劑氨基三亞甲基膦酸(ATMP)為原料、添加劑烷基酚聚氧乙烯醚(APEO)和鹵素鉀鹽的水溶液為封孔劑溶液在鎳鈀金電路板(PCB-ENEPIG)表面自組裝形成有機皮膜。通過(guò)電化學(xué)阻抗譜(EIS)、掃描電鏡研究了該有機保護膜的耐腐蝕性能及其形貌。實(shí)驗結果表明:有機自組裝膜對PCB-ENEPIG有較好的耐蝕作用,采用1.5 g/L ATMP、10 g/LAPEO、1 g/L碘化鉀得到的自組裝膜耐腐蝕性能最佳。

Abstract:A self assembly film on Ni, Pd, and Au printed circuit board (PCB-ENEPIG) surface was achieved by impregnating using amino trimethylene phosphonic acid (ATMP) as the raw material, a mixture of alkylphenol ethoxylates (APEO) and halogen salt in deionized water as solvent. Electrochemical impedance spectroscopy and scanning electron microscope were used to study the corrosion inhibition performance and morphology of self assemble film. The experimental results indicated that self-assembly film had a better corrosion inhibition effect on the PCB-ENEPIG while a highhas best corrosion resistance performance of the film was achieved using the recipe including 1.5 g/L ATMP, 10 g/LAPEO, and 1 g/L KI.
Key words:PCB-ENEPIG; ATMP2; self-assembly film; corrosion
