PCB production starts with a large piece of sheet material. Due to the limitations of PCB production equipment and manufacture capabilities, the factory has requirements for its minimum and maximum processing size. Therefore, under the guidance of manufacture instruction (MI), the raw material of PCB (Copper Clad Laminate) needs to be cut into the processing size by automatic cutting machine before production. (Copper Clad Laminate, short for CCL, is a type of material made of electronic glass fiber cloth or other reinforcing materials dipped in resin, laminated with copper foil on one or both sides and heat pressed.). In order to maximize the utilization of CCL, manufacturers design PCB panelization in advance and get the appropriate processing size. While cutting, size of panelized boards, PCB thickness, sheet material types, copper thickness, and spacing between components and the edge of the board are all factors to be considered.
