Initially PCBs were designed manually by creating a photomask on a clear mylar sheet, usually at two or four times the true size. Starting from the schematic diagram the component pin pads were laid out on the mylar and then traces were routed to connect the pads. If you have many questions of PCB Design, please come here!

Does anyone know there a standard matrix of clearances part to part for Class 2 and Class 3 board design. IPC does issue a preferred matrix but they are so liberal they not so useful in the real world. Any suggestions would really be appreciated.
