  1. What are the typical price differentials between 2,4,6 and 8 layer
    boards?

  2. Hi

    I haven't checked from 2 to 4 boards lately, but from 4 to 6 layers it
    is about 10% more expensive. Going from 35u to 70u layer stackup is
    about 5%.

    The thing about 2-4 and 4-6 layers is that the EMC can possibly be
    greatly improved and sometimes the board can be shrinked relative to
    the price increase so that it really do not cost anything to go to
    more layers

    Regards

    Klaus

    PS Be carefull with 70u, since the soldering quality can decrease due
    to problem with the stensil and etching
     
  3. Sounds like 6 layer might be the optimum for a high quality audio DSP
    board. That way I can get a separate analog power and ground.
