Hi

I would like to know if there are instruments/companies which produce any dielectric or substrate material with relative permittivity(dielectric constant) between 10 and 100 ? If yes, I would like to know if it's hard to do? and is it possible to create a substrate with a relative permittivity of for exemple, 16 or 66.2 precisely ?

Thank you
 


Not inexpensively and not for less than $200. Ceramic in general is more expensive compared to softboard.

Do you know what would be approx. the cost of 500 g of substrate with er=16? Does er level influence the subsrate price? Can we make any er between 10 and 100 with ceramic or softboard?
