通过银粉的不同形貌、粒径以及级配研究其对无铅导电银浆烧结后膜层的电阻率和附着力的影响。选取了平均粒径为0.50,0.91,2.09,3.36μm的球形银粉和4.3μm的片状银粉,首先将5种银粉各自制备成无铅导电银浆,选出银浆性能最优的银粉,再将此银粉搭配纳米级银粉和片状银粉制备无铅导电银浆。通过扫描电子显微镜(SEM)观察浆料烧结银膜的形貌,用四探针测试仪测量烧结银膜的电阻率,通过拉伸试验测试烧结银膜的附着力,讨论了银粉形貌及粒径对无铅导电银浆烧结膜附着力和电阻率的影响。结果表明,当为纯球形银粉或片状银粉时,球形银粉制备的银浆电阻率和附着力最优,且球形银粉粒径为0.91μm时最优,电阻率为33.3μΩ·cm,附着力为3.193 N;添加纳米级银粉能改善银浆的电性能,在添加量为4%时最优,电阻率为30.9μΩ·cm,附着力为3.253 N;添加片状银粉的含量在8%时最优,电阻率为27.7μΩ·cm,附着力为3.478 N。
Abstract：The effect of particle size and morphology distribution of silver powders on electrical resistivity and adhesion of silver film was investigated. Four kinds of spherical silver powder with mean particle size of 0. 5,0. 91,2. 09,3. 36 μm and one kind of flake silver powder with mean particle size of 4. 3 μm were adopted. Firstly,five kinds of silver pastes were prepared and the optimal performance of the silver paste with silver powder was attained,then the powder was mixed with flake silver and nano-silver powder and the lead-free conductive silver paste was obtained. The morphology of the paste sintered silver film was observed by scanning electron microscope( SEM),and the electrical resistivity was analyzed by the four-point probe meter,and the adhesion was tested by pull test.The effects of particle size and morphology on electrical resistivity and adhesion of silver film were discussed. The results showed that when morphology of silver was spherical and particle size was 0. 91 μm,the optimal electrical resistivity and adhesion of the silver paste could be obtained. And electrical resistance was 33. 3 μΩ·cm and adhesion was 3. 193 N. Nano-silver powder could improve the electrical properties of silver. And when the addition was 4%,the optimal electrical resistivity and adhesion of the silver paste could be obtained. And electrical resistance was 30. 9 μΩ·cm and adhesion was 3. 253 N. When the flake silver content was 8%,the electrical resistivity and adhesion of the silver film were the best. And electrical resistance was 27. 7 μΩ·cm and adhesion was 3. 478 N.
