#106410 - thank you kai i will try with solid gnd
Responding to: ???'s previous message
hello kai,

I was really neglecting the ground plane. But i do agree its good for noise immunity. now can we have ground plane using some good conducting foils just beneath the ckt pcb and connect it to ckt gnd.

I know this is silly but for testing purpose can we do this to give solid ground plane.
Or I can put my ckt in some aluminium box and connecting the box with gnd.

thank you,
