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,
