PCB Fabrication is the process of manufacturing PCB(Printed Circuit Boards). A PCB contains thin layer of copper foil and insulating layers dielectric and coating it by the solder mask. The solder mask could be of different colors like green, red, black, yellow, etc. The dielectric layers are typically laminated together with epoxy resin prereg. The dielectrics have capacitance and it is really an issue of how to eleminate the capacitance and many other environmental factors that depletes the PCB's quality
