welll after your breadboard testing...

you start with drawing efficient connection diagrams b/w components..

Peopole also use PCB s/w like PCB designer n all...

after that you get a plain PCB board...(not a U-PCB)

you draw your design on that using a marker ( a permanent marker)

THe marker ink covers the copper... and then you do something called "etching"

Etching is the process of dipping your marked pcb board into a soln of anhydrous FeCl3 + water + a bit of conc. HCl

This removes all the copper from the PCB except for places covered by the marker ink.... (takes lot of time though)

then you clean your board using spirit or ink remover to remove the marker ink...

then you drill at places where you were supposed to place the components n all... Thats it!!

Solder on!

hope this helps...
