PCB design in Design Spark

Let's just say you've mounted a new breadboard test circuit and once you finished you want to make it permanent. You could solder the entire circuit on a drilled pcb or make your own design of the PCB. In order to design a good pcb you have to follow some basic design rules. First of all make sure you gather all the information about your parts, components, and all the mesurements that you have to follow. Make sure you read all the datasheets, make sure you know all your CNC machine settings or the settings that your PCB manufacturer demands.
