    Substrate relative permittivity

    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

    Some ceramic materials with permittivity in the 20 to 40 range. https://en.wikipedia.org/wiki/Cerami...mic_capacitors

    thanks. do you know how it is possible to have a permittivity of 16? and is it possible to create inexpensively (for exemple less than 200$) some materials with any permittivity from 10 to 100?

    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?
