Based on electric-current-assisted sintering (ECAS) of silver paste, we propose a novel hermetic sealing method for the metal package. The monitoring of the temperature field during the bonding process shows that hermetic packaging based on ECAS of silver paste is a local heating method which has little impact on the component. During the process of ECAS, the heating rate of sintered joint dropped a lot with the removal of organics, and the reliable sintered joint is gradually formed after the removal of organics. Increasing the current gets higher peak temperature of the sintered joint, which is beneficial to form a denser and robust joint. The hermeticity of the sealed specimen and the shear strength of the sintered joint are improved with the increase of peak temperature. When the peak-temperature reaches above 400 °C, the joint will be dense enough to ensure the leakage rate of specimen below the reject limit.

基于电流辅助烧结银浆的金属封装气密密封新方法

基于银膏的电流辅助烧结（ECAS），我们提出了一种用于金属封装的新型气密密封方法。粘接过程中温度场的监测表明，基于银浆ECAS的气密包装是一种局部加热方法，对组件的影响很小。在ECAS过程中，随着有机物的去除，烧结接头的升温速率下降很多，去除有机物后，逐渐形成了可靠的烧结接头。增大电流将获得更高的烧结接头峰值温度，这有利于形成更致密且坚固的接头。随着峰值温度的升高，密封试样的气密性和烧结接头的剪切强度得到改善。当峰值温度达到400°C以上时，
