[0002] Prepreg, also known as "PP sheet", is one of the main materials in the production of multilayer boards. It is mainly composed of resin and reinforcing materials. The reinforcing materials are divided into several types such as glass fiber cloth, paper base, and composite materials. The prepreg (adhesive sheet) used in the production of multilayer printed circuit boards mostly uses glass fiber cloth as the reinforcing material. The treated glass fiber cloth is impregnated with resin glue, and then heat-treated (pre-baked) to make the resin enter the B stage to make the sheet material called prepreg. A cutting device is often used in the process of prepreg processing.
