摘　　要：采用傅里叶变换红外光谱仪、扫描电子显微镜X-射线能谱仪、X-射线粉末衍射仪、热裂解气相色谱-质谱联用仪对一种阻焊剂的化学成分进行研究,通过对测试结果的综合分析,确定出该阻焊剂主要由氮化硼和丙二醇单甲醚醋酸酯组成,其中氮化硼重量百分含量约占30%。The composition of an unknown solder resist was analyzed with Fourier transform infrared spectrometer,scanning electron microscope energy dispersive X-ray spectroscopy,X-ray powder diffractometer and pyrolysis gas chromatography mass spectrometry.The composition and proportion of this solder resist were determined based on these experimental results.The solder resist was certified to be mainly composed of boron nitride and 2-acetoxy-1-methoxypropane,and boron nitride accounted for about 30% through the evaluation of weight percentage.
