초록

신뢰성물리학 분석(RPA, reliability physics analysis)은 reliability 설계 및 개발 기법으로 수명을 예측하고 성능을 향상시키기 위한 과학적인 접근 방식이다. 본 논문에서는 해군 함정 무기체계에 탑재/운용되는 회로카드조립체에 신뢰성물리학을 적용하는 방안을 제시하였다. 우선, 운용되는 주변 환경을 분석하고 회로카드조립체 기초 정보를 기반으로 PoF 분석 툴인 Sherlock SW를 활용하여 수명을 예측하는 프로세스를 제시하였다.

Abstract

Reliability physics analysis(RPA) is a scientific approach to predict lifespan and improve performance with Reliability design and development techniques. In this paper, a process of applying Physics of Failure to Printed board assemblies(PBA) mounted and operated on naval ships was presented. First, it analyzed the ambient environment in which PBA are operated in ships, obtained basic information on PBA necessary for POF analysis, and presented a process of predicting lifespan using Sherlock SW, a POF analysis tool.
