Hi,
my customer sometimes will observe around 20MHz noise on VCC2(yellow line below), and the communication will be interrupted when there is noise:
They tried to unsolder VCC2 of the device to the pads and add a wire between VCC2 of the device and the pad on PCB to filter out the noise and the communication won't be interrupted any more. The wire act like an inductor.
So they think it would good for them to add a bead on VCC2.
Is it okay to do this? Are there any risk of adding bead to VCC2?
