While IPC-7351 is the overarching standard for generic surface mount land pattern design, IPC-7352 provides more specialized insights into terminal lead geometries. Ipc-7352 Pdf
The consensus in the industry is that the "Standard" for solder joint acceptability is IPC J-STD-001, "Requirements for Soldered Electrical and Electronic Assemblies". As such, IPC-7352 is presented as a set of best-practice design recommendations. Designers are expected to use their professional judgment and may need to adjust the geometric models to meet their specific company requirements, board fabrication capabilities, or assembly processes.
, officially titled Generic Guideline for Land Pattern Design , is the successor to the widely adopted IPC-7351B standard . Published by IPC, this document defines the mathematical models, package dimensions, and naming conventions used to design printed circuit board (PCB) component footprints. If you are looking for an IPC-7352 PDF , downloading and implementing this document is critical for ensuring reliable solder joints, minimizing assembly defects, and automating ECAD library workflows.

For years, the electronics industry relied on IPC-7351 for surface mount designs and IPC-7251 for through-hole designs. IPC-7352 represents a modern consolidation and update of these methodologies. It integrates newer component packages, adapts to advanced manufacturing tolerances, and refines the formulas used to calculate pad sizes based on component dimensions and fabrication capabilities.
