One of our costumer ask for dielectric constant certification on all
batches of PWB.
There are PWB fabricator that certifies it?. Is it a PBW fabricator or base
material fabricators responsability?.
Could press parameters afects so much the Er? (more then ± 5%).
Knows somebody the Er for fiver glass and Er for epoxy resin?.
There is a way to calculate it?.
I know, a lot of questions but I will realy apreciate your answers.

                                Thank in advance.
