how to design boards using high speed designing techniques

[pavani.karna459]

hi,
iam working as a pcb designer and at present working on proto type pcb design. i wanna know what is the difference between commercial, proto type and high speed designing. how we have to calculate track size and total finished board resistance. while i am designing analog and digital mixed boards interference problem occurring. how to solve it.

suggest me any guidance book for pcb designing from basic level and high speed design. iam unable to answer some of the questions what ever asking in interviews like what is ur making track size how u calculate track, how u will calculate finished board resistance and total current etc......

You have a lot of learning....
here is a list of links, documentation etc. that you may find useful, start with PCB related links...

You question is to ambiguous to provide a focused answer, such as track width, track width for what... Current capacity or to get a specific characteristic impedance?

Start by downloading the very comprehensive book at https://www.thehighspeeddesignbook.com/ Be prepared for a long learning curve.

Books:
Right the first time is a useful book for beginners as mentioned above.
High Speed Digital Design: A Handbook of Black Magic Hardcover – by Howard Johnson
Signal & Power integrity by -Eric Bogatin

There are several free calculation tools available on internet. You can check them. I found below links useful.
https://www.saturnpcb.com https://www.ultracad.com/ etc.

I would suggest from the initial post that Pavani learns to walk first, I think he has quite a long learning curve... I would leave the advanced detail of high speed till he get to grasp with the basics.....

Johnson's book is a classic.
Bogotin has a list of rules-of-thumb about when you can and can't ignore various effects, see https://www.edn.com/collections/4435129/Bogatin-s-Rules-of-Thumb
