If you work in the world of PCB design or manufacturing, you are likely familiar with the string of numbers that govern our industry: IPC-2221, IPC-2222, and of course, the land pattern standard IPC-7351.
Updated Component Families: Includes newer package types that didn't exist or weren't standardized during the last revision. Ipc-7352 Pdf
Released in May 2023, IPC-7352, "Generic Guideline for Land Pattern Design," is the current global standard that consolidates previous SMT and THT standards into a single, comprehensive document. It defines essential mathematical formulas, Producibility Levels, and Density Levels to ensure optimal solder joints and land pattern reliability. The standard can be purchased through authorized vendors such as IPC Official Store electronics.org The New Blueprint for SMT Design: Why You
Titled "Generic Requirements for Surface Mount Design and Land Pattern Standard," IPC-7352 is the successor to IPC-7351B. While it may look like just a version number bump, it represents a significant shift in philosophy regarding how we design pads for Surface Mount Technology (SMT). "What are the key differences between IPC-7351 and IPC-7352
Unified Scope: Integrates through-hole support, eliminating the need to look elsewhere for these standards.
