This book is the foundation building book for all engineers starting out to design PCBs. It teaches good habits designing a PCB, first for connectivity, and secondly, introduces the four most important principles to reduce noise. A seven-step process is presented: developing a plan of record, creating a Bill of Materials, completing the schematic, completing the layout, completing the assembly, conducting bring up and troubleshooting and documenting the project. Each step is developed in detail. In particular, the emphasis in this book is on risk management: what can be done at each step of the process to reduce the risk of a hard-error which requires a complete re-spin, or a soft error, which requires some sort of on-the-fly repair.
