本文通过超声楔焊过程,理论分析了塑性变形和界面的切向移动是提高焊接质量的两个主要因素,根据上述两方面因素,结合我们目前的多元光导碲镉汞器件流程中半过渡延伸电极形成区焊区的特点,提出了适合该工艺压焊区薄膜的最佳厚度在500nm以上,膜层要有良好的欧姆 In this paper, ultrasonic wedge welding process, the theoretical analysis of the plastic deformation and the interface of the tangential movement of the welding is to improve the quality of the two main factors, according to the above two factors, combined with our current multi-light guide HgCdTe device flow semi-transient extension electrode The formation of the characteristics of the zone welding zone, put forward for the process of welding the optimal thickness of the film in more than 500nm, the film should have a good ohm
