Hello, when shielding sensitive eletronics is the thickness of the metal shield im= portant? As I'm gonna pot my small circuit into epoxy, I'm tempted to use cheap alum= inium foil to shield the circuit (which seems necessary since I increased the clo= ck speed (PLLx16), and the environment is disturbed, at 1/16s speed it never c= rashed although all the EMI).
