I am assuming that you'll get your screen done elsewhere. You can do it yourself but its not easy to reach good yield. Anyways, after you get your circuit in a screen form, you basically paint a clean copper clad/laminate. After a while, you'll etch the board and then drill the holes. Later the paint can be removed with any off-the-shelft (...)

Can I use a 1 m long waveguide at 200 MHz, if it is filled with distilled water (then the wavelength will be about 18 cm), and made from copper-clad PCB laminate with the Cu layer on the outside? Won't I have problems with total internal reflection at the water/PCB dielectric interface?
1. My first question is about measuring relative dielectric constant Er of copper clad laminate. I read about ring resonators and other microstrip methods. But what if we do not have Network Analyser or any Spectrometer able to deal with high frequencies? Is using a RCL-meter is the only alternative? I just made RCL-measurement of raw (...)
Prepreg has a specific function in multi-layer PCB. The full name is preimpregnated bonding layer, which should already answer part of your questions. If you are interested to understand the possible ways to combine copper-clad laminates, prepreg layers and copper foils to multi-layer PCB, you should study the PCB (...)
