Hi, You can use something called a via to connect a trace on one side of the board (green trace) to a trace on the other side of the board (red trace). A VIA is used when traces cross one another. It's a similar idea to the link you'd use on a stripboard. It's best to try to place your components in a similar position to the way they appear in your schematic to start with. Placement is an iterative process, so do it in stages then stop and try doing it again. As you spend time with the layout better routes for the traces will suggest themselves. It's probably best if you try to do the board yourself as you will learn a lot more this way. If you have any problems ask away, there are many helpful people on here who can assist.
David.
