I am Ananya. Different PCBs are made up of different materials. I have a certain knowledge that as distance increases, impedance increases and loss in signal occurs in PCB. I wanted some information on the material losses in different PCB materials over distance. Which kind of material suffers higher loss and which is better. I would be grateful if i could get some references for the same.
Since we are not a PCB manufacturer, we do not have this information. I suggest you work with your local PCB vendor to understand what choices they offer and how it affects your performance.
We support power applications. We try and use good RF techniques: Low impedance ground plane (thin board with multiple vias) and small loop areas. This also give good thermal performance. If you are looking for someting more like impedance matching you will have to consult with a good RF engineer, which would be a different group.
