*Separate Electric furnace and other system like Electronic scale
-Because Electric furnace temperature is very high
so we need to protect other system.

04. The incidence of failure following single-visit endodontic therapy
Richard B.Pekruhn. J Endod 12:68-72. 1986
Introduction
- Single-visit 근관 치료와 multiple-visit 근관 치료사이의 실패율 유의차 없음
- Single-visit 근관 치료는 다음 세 가지로 분류
① 초기접근, 근관 형성, 근관충전이 single-visit 근관 치료로 완료
② 통증
Ag-Cu계가 이용되고 있고 리플로우용 솔더 페이스트로는Sn-3.0wt%Ag-0.5wt%Cu 솔더가 대부분 이용되고 있다.
그러나 위 솔더들의 원자재가격 상승 및 고온, 고진동 하에서 접합강도의 취약성을 보완하기 위해 최근 Sn-0.3wt%Ag0.7wt%Cu와 같은 Ag의 함량이 1.0wt% 이하인 낮은 Ag 조성의 무연솔더 적용이 검토되고 있
