It is easier to use that more sophisticated programs but can t do simulations. Easytrax shows the PCB looking thru it from the Top to the Bottom layer.
Components go on the top layer and most wiring tracks go on the bottom layer.
Generally try to separate traces by widths about equal to the trace width. Make your board as small as possible to reduce manufacturing costs. For Ground Plane, DO NOT layout your tracks on the bottom layer. You MUST submit the ECE Shop PCB Request form. You will need to run Easyplot.exe on your .PCB file to generate the Gerber files.
