Issues to Consider in the Production of High-Frequency Microwave Printed Circuit Boards (PCBs)

Engineering Context / Abstract High-frequency microwave PCB production requires tighter material, geometry, and process control than conventional FR-4 fabrication because the board itself forms part of the RF transmission structure. At microwave and millimeter-wave frequencies, small changes in dielectric constant, dielectric thickness, trace width, copper profile, via geometry, solder mask, or surface finish can alter...
