hello! Ive been working with Diptrace for a couple of days now. Its for sure better than Eagle, atleast in my experience. Howrever, right now I am stuck with the idea of a ground plane. I followed a tutorial on line that used a battery connecter, a 7805 reg, couple of caps, a resistor and an LED...*the usual stuff* - What is a ground plane and why do I need it. Ive read a lot of articles on it but nothing really dealt with the above question. I know that the circuit I have is simple and dont need a ground plane, but I do need to understand the concept. -For first trail and error purpose, I did establish a ground plane (connected to the -ve terminal of the battery). But the layer chosen when I dropped the ground plane was "TOP" (in diptrace). So what does this mean? The top layer has the ground? and what about the bottom layer? Why cant I put the ground pour on the bottom layer?. -Im going to make this PCB *hopefully* with the art of DIY at home. So im going to be applying the toner transer method using a hot iron. Now, when I print this circuit and transfrer it to the copper board, where will I place the components them selves? On the other side of the board which will be completely etched? On the side where the image had been transfered and etched accordingly? I know these are basic and redundant questions, but I fialed to find an extensive explanation of ground plane in Diptrace (or atleast I couldnt find it). So im hoping that someone here would help me ..........PLEASE!!! and also I think im going bald.ive pulled out my hair over these basic questions!!!!
