Understanding Prepreg in PCB Manufacturing What is Prepreg? Prepreg, short for pre-impregnated, is a composite material used in the manufacturing of PCBs. It consists of a reinforcement fabric, typically made of glass fibers, that is pre-impregnated with a partially cured thermosetting resin, such as epoxy or polyimide. The resin is in a semi-solid state, allowing…
