The IPC-7352 standard, titled "Generic Guideline for Land Pattern Design," is the May 2023 replacement for the widely used IPC-7351B. It provides essential guidelines for the geometry of land patterns (footprints) used to attach electronic components to printed circuit boards (PCBs). Key Highlights of IPC-7352
Design Focus: It establishes recommendations for achieving optimal solder joints for surface-mount devices (SMD).
Replacement of IPC-7351B: While IPC-7351 was a strict standard (Surface Mount Design and Land Pattern Standard), IPC-7352 is categorized as a guideline, offering more flexibility for company-specific modifications. Naming Convention Changes:
It reverts the component naming convention to the style used in IPC-7351B, placing the Pin Quantity at the end of the footprint name.
Example sequence: Component Family + Pin Pitch + Package Dimensions + Pin Quantity.
Dimensional Units: Metric units (millimeters) are the preferred standard for all linear dimensions, while temperature is specified in degrees Celsius. Accessing the Standard

IPC-7352 - Generic Guideline for Land Pattern Design - BSB EDGE Ipc-7352 Pdf
IPC-7352, titled Generic Guideline for Land Pattern Design, was released in May 2023. It serves as a comprehensive guide for designing land patterns (footprints) for both surface mount and through-hole electronic components on printed circuit boards (PCBs).
This standard is intended to replace and consolidate the previous IPC-7351B (surface mount) and IPC-7251 (through-hole) standards. Core Content & Purpose
The primary goal of IPC-7352 is to provide optimized land pattern geometries that ensure reliable solder joints meeting J-STD-001 requirements while allowing for proper inspection and rework. Key content includes:
Land Pattern Geometries: Guidelines for the size and shape of landing pads based on component terminal types. Three Density Levels:
Level A (Maximum): Most land protrusion, ideal for low-density products and wave soldering.
Level B (Median): General-purpose design for standard density.
Level C (Minimum): Least land protrusion, suited for high-density applications with reflow soldering.
Naming Conventions: Updated naming rules for footprints and pad stacks, though some elements reverted to the older IPC-7351B style regarding pin quantity placement.
Mounting Conditions: Guidance on solder mask clearance, stencil apertures, component spacing, and "keep-out" areas. Standard Structure & Component Coverage
The document is roughly 56 pages long and covers a wide array of component families:

To understand the weight of IPC-7352, you have to understand the limitations of its predecessor. IPC-7351 was a landmark document, but it operated on a generalized philosophy. It provided standard land patterns based on nominal component dimensions.
In the era of the SOP (Small Outline Package) and basic QFPs (Quad Flat Packages), this worked fine. But as the industry moved toward QFNs (Quad Flat No-leads), BGAs (Ball Grid Arrays), and microscopic passives (like 0201s and 01005s), the "nominal" approach began to crack.
Designers were finding that following the standard didn't always guarantee a good solder joint. Why? Because IPC-7351 didn't fully account for the actual termination shape of the component. It treated a gull-wing lead roughly the same way it treated a flat termination, mathematically speaking. The result was often pad sizes that were too large or too small, leading to tombstoning, floating parts, or short circuits.
Searching for a PDF of IPC-7352 is not just about having a file on your hard drive. It is about accessing critical data that impacts manufacturing yield.
IPC-7352 didn't just update the numbers; it overhauled the math. The standard introduces a new, highly sophisticated algorithm for calculating land patterns.
The core innovation in IPC-7352 is its focus on Component Termination Geometry.
Instead of simply adding a percentage to the component size, IPC-7352 calculates the pad based on the specific physics of the solder joint. It breaks the pad calculation down into three critical dimensions:
This might sound like splitting hairs, but in Surface Mount Technology (SMT), hair-splitting is the name of the game. By customizing these three variables, IPC-7352 produces a pad that is optimized for the specific way the component connects electrically and mechanically to the board.
Pick-and-place machines have tolerances. The IPC-7352 PDF contains algorithms that adjust land pattern sizes based on the expected placement accuracy of your assembly house.
As of 2025-2026, IPC-7352 is the current standard. However, working groups are already discussing IPC-7353, which will focus on AI-generated land patterns and embedded components. But for now, mastering the IPC-7352 PDF is the benchmark for professional PCB design.
IPC-7352 is the official industry standard titled "Generic Requirements for Surface Mount Design and Land Pattern Standard." Published by the Association Connecting Electronics Industries (IPC), this document provides the requirements for creating land patterns (also known as footprints or pads) for surface mount components.
The standard is critical because it ensures that the copper patterns on a PCB match the physical leads of components like resistors, capacitors, QFNs, BGAs, and connectors. Without a unified standard, a component from one manufacturer might not fit the land pattern designed from another’s datasheet. Benefits of IPC-7352 The IPC-7352 standard offers several
One of the most practical features carried over and refined in the IPC-7352 methodology is the concept of Density Levels. Recognizing that not all boards are created equal, the standard provides three distinct footprints for almost every component:
IPC-7352 refines the calculations for these levels with greater precision than ever before, allowing designers to make informed trade-offs between board size and manufacturing yield without guessing.
