Abstract :
The key contender packaging systems for high specification surface mountable (SMT) DC-DC power converters are reviewed. Various substrate, leadout and encasing options are examined for reliability and true surface mountability. Both open-frame and moulded designs are studied. Thermal performance comparison data are presented. Mechanical performance criteria, evaluating the power converter as an SMT component are outlined. Manufacturing and end-user process issues are discussed. Electrical design caveats are outlined
