Ideally, the electrical engineers can simply suggest the circuit components as the software is capable of automatically place and route them properly on the design. At certain cases, engineers may require to do minor editions to achieve a particular desirable effect if they wish to create experimental circuitry designs.
The design that is created with the help of the PCB layout software is printed either onto the copper clad circuit board or onto a specially designed trace sheet. Next, the PCB is then soaked in an etching solution to wash off the unwanted conductor from the board. This leaves just the final PCB circuit design.
This specific process has the benefit of eliminating the lengthy trial and error testing process while designing the experimental circuits. Apart from these benefits, some highly technical PCB layout software are also capable of alerting the users about existing flaws, dangerous configurations and errors in the design before they are finally etched in the circuit boards.
