Connecting to GND and VCC planes while routing

AKSHAYA

Hi

    I have created a board with four layers. The inner layers are ground and VCC and the VCC and GND nets of the circuit made electrically connected to these planes by changing the net name. How we can connect the top and botton VCC and GND tracks to these planes. Is it possible using via, burried via or blind via. Whether we can put vias where ever connections are required or we have to connect using only one two vias. If vis is to be used what should be  the specifications of thermal pad and anti pad?. I am using only SMD pads.

Hope somebody may be able to help me

  •  Hi

    Not to be rude, you questions covers so many aspects and it is not easy to explain 

    I would recommend you to attend some classes whcih will enable you to understand why certain things are done

    My reply will answer your question but will not explain why 

    Please go throught the documents available at

    <CDSROOT>\SPB_16.2\doc\algroroute

    <CDSROOT>\SPB_16.2\doc\algroman

    and search in google for pcb design tutorial

    I got 10200000 hits

    the first one seems really good

    also search for PCB DFM guidelines which will explain the via dimensions and every other aspect
