Re: Need e books for PCB designing and also to learn PADS pcb designer software.
I don't have any ebooks but you can get a lot of video tutorials about "EAGLE" PCB design software by Cadsoft on Youtube.
Just type EAGLE tutorials.
Also you can download the setup file of recent version of EAGLE from
While installing you can run the software as "freeware" and you can use it all the time.
