高温烧结型铜电子浆料的导电性
针对铜电子浆料导电性能低、成本高等问题,以铜粉及有机载体为原料,通过手工将丝网印刷到陶瓷基板上,600℃烧结后制备出高温烧结型铜电子浆料,并利用四探针测试仪测试烧结后铜膜的方阻,分析有机载体、铜粉粒径大小及铜粉含量对浆料导电性的影响.结果表明,当有机载体中乙基纤维素质量分数为5%,浆料中10μm和1μm铜粉质量比为7∶1,总铜粉含量为80%时,烧结后的铜电子浆料导电性能最佳,方阻最低可达1.17Ω/□....

| Abstract_FL | To solve the problem of low conductivity and high-cost,a new copper electronic paste was prepared with copper powders and organic vehicle by hand screen printing on the ceramic substrate and then sintered at the temperature of 600 ℃.Four-probe tester was used to measure the square resistance of the sintered copper films,and the effects of organic vehicle copper powder size and content on electrical conductivity of paste were analyzed.The results show that when mass fraction of ethyl cellulose in organic vehicle is 5 ％,the mass fraction of copper powder in electronic paste is 80％,with mass proportion of 10 μm and 1 μm being 7 ∶ 1,and thus the sintered copper paste has the highest electrical conductivity and the minimum square resistance reaches to 1.17 Ω/□. |
