Abstract

In this paper, the ultrasonic horn having the natural frequency with 60 [kHz] for the dissimilar material bonding of the glass and solder tried to be designed. The ultrasonic horn was designed through the relational formula including the aspect ratio of the input terminal and output terminal, length of the ultrasonic horn. The modal analysis was performed for the propriety analysis of the designed horn. The parameters and response was set through the basic experiment. The dissimilar material bonding strength analysis using the ultrasonic transducer was done. The optimal process parameters having maximum bonding strength was derived.

본 논문에서는 유리와 구리의 이종재료 접합을 위해 고유진동수를 60 [kHz]로 갖는 초음파 혼을 설계하고자 하였다. 초음파 혼의 입력단과 출력단의 단면비, 혼의 길이 등 관계식을 통해 설정하였으며 설계된 혼의 타당성 분석을 위해 모달해석을 수행하였다. 기초실험을 통하여 공정변수 및 반응변수를 설정하였으며, 초음파 공구 혼을 이용하여 이종재료 접합 강도 실험을 실시하였다. 또한 실험 결과를 통해 최적 공정조건을 도출하였다.
