IPC-7352 maintains the industry-standard philosophy of classifying land patterns into three distinct geometric variations. These variations depend on the density and reliability requirements of the end product.

But as electronics shrank and tolerances tightened, the old bible needed a new testament. Enter .

The primary goal of IPC-7352 is to establish a consistent set of rules for CAD designers and engineers. Rather than providing a static list of dimensions for every component in existence, it focuses on the used to calculate land patterns based on:

This has standardized the industry. Today, a footprint generated in Altium in California using IPC-7352 rules will be virtually identical to one generated in KiCad in Berlin. This global interoperability reduces supply chain friction and minimizes the risk of footprint errors—one of the top causes of board spins.

Contract manufacturers routinely evaluate PCB source files against IPC-7352 criteria before spinning prototypes. Compliance guarantees smoother transitions from prototyping to mass production.

Minimum land protrusion; designed for high-density, ultra-compact layouts like smartphones.

IPC-7352 maintains the classic three-tier approach to land pattern geometry, allowing designers to choose the right balance between density and manufacturability:

For years, the industry benchmark for footprint design was the IPC-7351 series. However, manufacturing technologies, automated optical inspection (AOI) capabilities, and extreme miniaturization forced a significant structural update. Legacy Standard: IPC-7351B Current Standard: IPC-7352 Exclusively Surface Mount Technology (SMT)

Includes newer package types that didn't exist or weren't standardized during the last revision.
