5 Ipc-7351 (2025)

The (specifically the current version IPC-7351B ) is the industry-standard "Generic Requirements for Surface Mount Design and Land Pattern Standard". It provides designers with a consistent, mathematical approach to creating PCB footprints—ensuring that land patterns (the pads where components are soldered) are optimized for high-quality solder joints and efficient manufacturing. Key Pillars of IPC-7351

The standard is built around five core areas that allow for global standardization in PCB design: IPC 7351 Standards to Design a Footprint - Sierra Circuits 5 IPC-7351
