: Align your company’s internal design rules (DFM) with the specific Density Level (A, B, or C) that matches your primary target manufacturing house.

In the world of printed circuit board (PCB) design, land pattern creation—often referred to as footprint design—is the foundation of manufacturing yield, electrical performance, and long-term product reliability. For nearly two decades, engineering teams relied on IPC-7351 (for surface mount devices) and IPC-7251 (for through-hole components) to calculate pad sizes, tolerances, and courtyard boundaries.

IPC-7352 is a standard developed by the IPC (Association Connecting Electronics Industries) that establishes the generic requirements for surface mount land pattern design. It acts as the modern successor and consolidation point for older footprint design frameworks.

IPC-7352 acknowledges that most designers use CAD software with built-in calculators or library tools (like Ultra Librarian or PCB Library Expert). The standard provides data in a format that is more easily digested by these automated tools, reducing the margin for human error when entering data.

For designers familiar with IPC-7351, understanding the differences is crucial. The chart below summarizes the key distinctions between IPC-7351B and IPC-7352. : standard, titled "Generic Guideline for Land Pattern

: Moving toward proportional pad stacks where annular ring sizes scale with hole diameter rather than fixed tiers. Comprehensive Documentation

As IPC standards are intellectual property, they are generally not available as free, legal PDF downloads. You can obtain official copies from these authorized providers:

IPC-7352 is already being integrated into professional PCB design workflows, particularly through powerful tools like . This software, widely used for creating IPC-compliant footprints, transitioned to using the IPC-7352 mathematical model in May 2023. The ipc-7352.opt option file within the tool applies the new pad stack calculations and naming conventions. However, users often have the flexibility to choose between IPC-7352 and other standards, like the older IPC-7351B or proprietary naming conventions. IPC-7352 is a standard developed by the IPC

The IPC-7352 PDF is widely used in the industry, and its relevance cannot be overstated. The standard is essential for companies that design and manufacture electronic components, as it helps to ensure that their products meet industry standards and regulations.
