Design for Reliability: PCBs - DfR Solutions

ConclusionoThe base knowledge and understanding of PTV Fatigue isrobustooDecades of testing and simulationUse of reliability physics is best practiceoDetailed understanding is still missingooKey expertise (process parameters, material properties, simulation,testing) is rarely in the same organizationNot a pure science activity (significant amount of human influence)oImprovements in out-of-plane CTE and plating properties havegreatly improved PTV performanceoAvoiding defects continues to be the biggest risk© 2004 - 2007 2010
