My Questions: 1-) If i create GND Plane on Bottom Layer(Blue) and add vias at around PCB.Is there any objection? (Look undermost image) Normal PCB With Faraday Cage PCB

You can add a copper shield, (blue color) but this cannot make a great advantage. The RED plane are the most important, reference (GND) and EMI shield plane. Skywalker. Last edited: Nov 29, 2013
