DC/DC converters are widely used in industrial, aerospace and other fields. The reliability of DC/DC converters is very important for the whole electronic system. Overheat is the key factor infecting the reliability of DC/DC converters because of the power density of the device. Three-dimensional thermal analysis modules include heat distribution analysis and thermal stress analysis at 25 °C in this...
This paper described a ceramic ball grid array (CBGA) and its second level reliability. The CBGA uses a substrate with high coefficient of thermal expansion (CTE) and leadfree soldering. The reworkability of the BGA package and board was also studied. The results have shown that this package is reworkable without a significant reliability reduction in the board level reliability. The reliability of...
This paper intends to provide a contribution for a better understanding of the self-heating effect in BAW SMR by developing a predictive 1D-model. Knowing the power dissipated inside the SMR, the presented model allows us estimating the temperature distribution inside the different layers of resonators used to build BAW filters. Model is compared with both experimental measurements and Finite Elements...
