The printed circuit boards are can be much difficult to design if you are beginner, however learning the layout design of PCBs is not that difficult. The most difficult thing in the PCB layout design is making the layouts and intersecting these layers along if PCB is multi-layered. You may be requiring the use of the copper layers and making the traces on both sides of the PCBs.
To have a perfect design of the Printed Circuit Board, you are required to have the schematics which you would require to simulate. The basic simulations is of great importance because this is going to be the basic structure of your PCB layout. You can use different software fort the schematics such as Proteus and Multi-sim etc. The following is a basic picture of the schematics.
The PCB layout is something which appears on the board is acting as the basic feature of your gadget. The PCB layouts can also be made through different software however, EagleCad and Diptrace are adopted by students at most worldwide. The technique is either to import the schematics to the software and then auto route it or make the entire layout yourself. You have to put the elements being used in the schematics and then join the elements, these are appearing as the copper routes on the PCB board.
