RF design with PCBWAY FR4 prototype PCB's

Marcus Simons asked May 14,2024

For a 2 and 4 layer FR4 -based PCB, what is the Permeability Er of your FR4 material? and what is the exact layer stackup?

I need these for proper RF design:

Total thickness of ~1mm and ~1,6mm is what we use most

Can you give us this info? Other customers will like this info too, I am sure.

Many thanks,
