Ipc-7352 — Pdf
(released May 2023 ) is the current "Generic Guideline for Land Pattern Design" . It officially replaces the older IPC-7351B standard for PCB footprint determination. Key Differences: IPC-7351B vs. IPC-7352
, titled the Generic Guideline for Land Pattern Design , is a critical industry standard that provides the methodology for designing surface mount land patterns (often called "footprints") for printed circuit boards (PCBs).
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: Ipc-7352 Pdf
| Density Level | Description | Typical Use Case | | :--- | :--- | :--- | | | Maximizes solder joint size and strength. | High-reliability applications like aerospace and medical devices. | | Nominal (N) | Standard, balanced design for most applications. | General commercial and industrial electronics. | | Most (M) | Minimizes land pattern size for high-density routing. | Consumer electronics where space is at a premium (e.g., smartphones). |
Are you optimizing your board layout for or low-volume, high-reliability systems (e.g., aerospace, medical)? Share public link (released May 2023 ) is the current "Generic
The IPC-7352 is a "Guideline," meaning it provides standardized recommendations. However, it is highly recommended that companies review and, if necessary, modify these guidelines to meet their own specific board technology requirements. Components of a Land Pattern in IPC-7352
Yes, IPC occasionally offers a free "Preview" PDF (usually the first 10-15 pages) which includes the table of contents and scope. This is useful for understanding the standard’s structure without purchasing it. IPC-7352 , titled the Generic Guideline for Land
This marks the first time through-hole design guidance has been officially integrated into the 735x series. It includes:
