Hello,
I am making a 4-Layer PCB.
When I made 2 layer PCB, I put GND plane on Top and bottom layer. But when I am doing 4 layer I have top, bottom, GND and power layer. But I do not know what should I do with the GND and power layer. Do I still have to do GND plane on top and bottom layer?
What is the GND and Power plane for?
Should I make three GND plane: 1 on Top, 2. Bottom and 3. On GND layer?
I am confused?
And what do I do with power plane?
