专家回复:QFN sawn or micro-lead pins are fully encapsulated and do not allow for as much movement – mainly associated to high power components due to temperature changes Cracks in the mould compound can lead to failure of the MOSFET LFPAK pins allow for thermal expansion due to temperature difference between the MOSFET & PCB and also mechanical strain due to PCB bending & flexing | |
