The Companion Guide to... DFM Essentials: Tips for Designing for Manufacturing

This book is a comprehensive reference for PCB designers aiming to optimize their designs for manufacturability. It covers essential topics including preferred manufacturing data formats (like ODB++), fabrication notes, material specifications, layer stackups, controlled impedance, solder mask and surface finishes, and special requirements such as via fills and back-drilling. This guidebook also outlines common CAM issues and emphasizes early collaboration with fabricators to avoid costly design errors. Authored by American Standard Circuits and ASC Sunstone Circuits, readers will find this book reflects decades of expertise in delivering high-performance, reliable printed circuit boards.

The Printed Circuit Designer's Guide to... DFM Essentials

One of the biggest challenges facing printed circuit board designers is not understanding the cost drivers in the PCB manufacturing process, particularly the manufacturing of advanced technology PCBs. Design for Manufacturing (DFM) is defined as the practice of designing printed circuit boards that meet not only the capabilities of the customer’s assembly manufacturing process but also the capabilities of the board fabrication process to provide the highest reliability at the lowest possible cost. The guidelines offered in this book are based on both ASC recommendations and IPC standards with the understanding that some may require adjustment based on the material set, fabricator processes, and other design constraints.
