Standard PCB
For PCB designers, the must-read IPC standard is the IPC-2221. The IPC-2221 is the generic standard that covers almost every aspect of PCB design. The standard details how electrical considerations such as PDN bus layouts, conductor clearance, and impedance control should be implemented on a PCB.
