Robust polymer-based composites with high thermal conductivity (TC) and electromagnetic interference shielding effectiveness (EMI SE) hold great promise for applications in rapidly developing electronics. Traditional containing inorganic fillers often suffer from increases processing difficulty, density, significant deterioration mechanical properties. Herein, we report the first time a flexible multilayered all-polymer composite of poly(p-phenyl-2,6-phenylene bisoxazole) (PBO)...
研究了230℃,5×103A/cm2条件下液-固电迁移对Ni/Sn-9Zn/Ni线性焊点界面反应的影响.在液-固电迁移过程中,Ni/Sn-9Zn/Ni焊点表现出明显的反极性效应,即阴极界面金属间化合物（IMC）持续生长变厚,并且一直厚于阳极界面IMC.由于排除背应力的影响,Sn-9Zn液态钎料中Zn原子的反常迁移行为归因于其有效电荷数在高温下为正值,即在电子风力作用下Zn原子向阴极界面定向迁移,从而导致焊点在液-固电迁移过程中发生反极性效应.回流焊后,Ni/Sn-9Zn/Ni焊点两侧界面上均生成了较薄的Ni5Zn21层.液-固界面反应过程中（无电流）焊点两侧界面IMC均随时间延长而生长变厚,从而消耗钎料中的Zn原子并使界面处的相平衡发生变化,导致界面IMC由Ni5Zn21转变为[Ni5Zn21＋（Ni,Zn）3Sn4].与之相较,液-固电迁移过程中阴阳两极界面IMC的类型一直为Ni5Zn21,并未发生IMC类型的转变.这是由于,在电子风力作用下,阴极界面附近钎料中Zn原子的含量充足,Zn与Ni反应生成Ni5Zn21型IMC;同时,电子风力也阻碍了Zn原子向阳极界面的扩散,从而抑制...
