최근 우리나라는 카드3사의 개인정보 유출 등으로 보안 산업에 대한 관심이 높아지고 있다. 경영자들은 개인정보 유출 등 보안 사고에 의한 피해가 어떠한 재무적 위험보다도 더 위험한 요소로 인식하고 있다. 지식정보보안 산업은 과거 물리보안 및 네트워크 보안에 서 최근에는 사회 안전 및 시설보안 등 융합 산업 보안으로 진화하고 있다. 관심분야도 방화벽이나 Anti-virus 등에서 스마트폰보안 및 지능형영상보안 등 융합보안 산업으로 변해 가고 있다. 융합보안은 시설경비나 출입통제 중심에서 최근에는 공공기관 및 대기업을... -

지금 까지 전자패키지 접합에 사용되어온 Sn/37Pb 솔더는 낮은 용융온도와 우수한 물리적 특성, 그리고 저렴한 가격 등으로 널리 사용되었다. 그러나 납의 독성으로 인한 환경문제와 인체 유해성이 문제화되면서 이를 대체할 무연솔더의 요구가 시급한 실정이다. 또한 제품의 소형화에 따른 접합부의 미세화로 인한 접합부신뢰성이 요구되고 있다. 본 연구에서는 현재 Sn/37Pb 솔더를 사용하여 제품에 사용되고 있는 48 $mu$BGA 패키지를 사용하여 Sn/Ag 계열 의 두 무연솔더인 Sn/3.5Ag/0.75Cu와 Sn/2.0Ag/0.5Cu/2.0Bi를 접합하여...
