The is a planned update to the IPC-7351B "Generic Requirements for Surface Mount Design and Land Pattern Standard". While IPC-7351B has been the industry standard since 2010, the "C" revision introduces significant modernization to address high-density electronics and automated assembly requirements.

Yet, thousands of engineers hunt for it. Why? ipc-7351c pdf
IPC‑7351C, "Generic Requirements for Surface Mount Design and Land Pattern Standard," is the industry standard that defines land pattern (footprint) geometry and design rules for surface‑mount components on printed circuit boards (PCBs). The standard provides recommended pad sizes, component land pattern variations (least, nominal, most), and design considerations to ensure manufacturability and reliable solder joints.
