Initially PCBs were designed manually by creating a photomask on a clear mylar sheet, usually at two or four times the true size. Starting from the schematic diagram the component pin pads were laid out on the mylar and then traces were routed to connect the pads. If you have many questions of PCB Design, please come here!

It is started from which frequency range that we need to apply the high speed PCB design rules ? Reply 2016-05-12 17:05:13

I'm wondering that starting from which frequency range we need to apply the high speed PCB design rules and techniques ?

If the electrical length of a trace is longer than 1/10 wavelength, you need to treat it as a transmission line. The 1/10 wavelength applies to the speed of the signal on the PCB, which is less than the speed of light.
