Aeronautics safety strongly depends on the Quad Flat Non-Lead (QFN) reliability, whose junction temperature must remain as low as possible during operation. The power must remain below 0.1W, making the QFN64 model most relevant under these operating conditions. This study aims at improving the thermal design and reliability of the QFN64 device for embarked electronics. Numerical results are confirmed by thermal and electrical measurements carried out on prototypes for all ...
