The board for the IR-12 Infrared Circuit Test unit was designed using Express PCB because the layouts are easy to make. I don't have many suggestions once you've learned the program. A few simple hints when using this program are to increase the thickness of your connecting traces to .030", from the default .010". Draw the traces and pads on the green (bottom) side of the board. When you iron them onto a PCB later, they'll be oriented correctly.
The program often defaults letters and lines to the red/top side, so I double check them. The components automatically get placed on the top side which is OK because the red pads will be on the bottom layer. If you make a custom component with specific lead spacing, remember to save and name it. Lastly, the pads for the components should also be enlarged a little from the default. I use .062" square or round pads with .029" holes or .070" square or round pads with .033" holes. When you drill the holes, it's much easier. If the pads are too small, I sometimes tear the copper traces off the PCB when drilling.
