  Subject: [TN] Laminate Materials


  Hi,

   

  I am searching high performance laminates, prepregs and adhesives. I have found some laminates - FR4/406/408, Arlon33n/35n/85n...,Speedboard, N4000/6000..., RO3003/3006/3010...-  with their specifications, I want to get much more information about laminates such as:

   

  -Can I design a PCB with different laminates for each or some layers? 

  -Can I design a PCB with different laminate thickness for each or some layers?

  -If they can be done, how can the tolerans be determined?

  -If they can be done, how can we calculate the impedance?

   

  Moreover, I need addresses of PCB manufacturing companies for high speed/high frequency design.

  I am waiting your responce.

  Thank you,
