i am doing a timer project in pic16f877a to control 3phase motor. to prevent emi i am using rc snubber in the motor side then using line filters in the microcontroller supply side then i am also using 5v TVS diode, more than this to prevent external emi i am covering the whole pic board with aluminium box and connecting the aluminium box to the negative supply(-) that is ground exactly telling 7805 voltage ic center pin that is pin2. my doubt is that can i cover the entire board with aluminium box and connect to 7805 center pin that is ground 0v?
