Could I supply you FR4 board to use for my jobs?

Postby drkirkby » Wed Aug 22, 2012 9:41 am

I want to place a microstrip antenna on a PCB. However, the resonate frequency of the antenna will be changed by the properties of the PCB substrate. Rather than use a PCB which has a well defined value of Er like Rogers, if possible I'd like to use cheap FR4, but measure the permitivity myself. Once I know the properties of the board, which I can measure with a network analyzer, I'll be in a position to change the dimensions of the antenna so it resonates at the frequency I want.

So would it be possible to send FR4 from you, where I know the properties, then you use that for making me a PCB?

I asked our manufacturing manager if your request was possible and received the following questions.

Does he want us to use the exact piece of material that we would send him initially for measurement (we send him a 14x16 .062, he does his analyzing, sends the piece back, we build his design on that piece? We can do that, but we would need to charge a bit more. Could you clarify what he needs?

Please feel free to contact support if you have any questions.
