以是否采用辅助烧结、银浆中石墨烯的不同掺杂量、烧结功率和基体材料开展了微波烧结银电极的研究。结果表明:采用碳化硅片辅助烧结和向银浆中掺杂微量石墨烯均可缩短微波烧结时间;在烧结功率为1000W时得到的银电极的电阻最小,为28.11mΩ,附着力最好,为1.97kg;烧结峰值温度的高低对微波烧结效果有一定影响。
Microwave sintered silver electrodes were studied with or without auxiliary sintering,different doping amounts of graphene in silver paste,sintering power,and matrix materials.The results shown that the sintering time can be shortened by using SiC-assisted sintering and doping a small amount of graphene into the silver paste.The resistance of the silver electrode obtained when the sintering power was 1000W was the smallest,which was 28.11mΩ,and the adhesion was the best 1.97kg.The sintering peak temperature had a certain effect on the microwave sintering effect.
