    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (232 KB)

    Traditional algorithms for determining defective components using circuit card data can provide inconsistent results. Model-based tools and expert systems derive conclusions using circuit performance data, circuit theory and statistics. The authors have developed a predictive sensitivity approach which views failure paths and actual failure data to identify alternate fault-isolation strategies View full abstract»
