2 layer layout help
I am having trouble laying out my 2 layer board.. I have attached a jpg and the Protel PCB file that I'm using. My problem is that I don't know if it will be stable enough.. there's nothing too high speed on it (RS 232 and a FTDI USB chip). I have been reading High-speed digital design by Johnson, and in one section, he recommends using one layer with horizontal power stripes across hte whole board, and the other layer having perpendicular ground stripes (and placing components in between). Is this method much better than what I have? I submitted my file for quote, and the PCB guy saying I would be better off fitting all teh components on the top layer, and using the bottom for a solid ground plane. However, I don't see how I will be able to route all the signals on the top layer!! Any suggestions?
