Use stitched via arrays underneath exposed pad ICs (like QFNs) to conduct heat away from the component into internal ground planes.

To prevent electrical arcing and short circuits, IPC-2221 provides definitive lookup tables for minimum spacing between conductors. These clearances are determined by: The voltage difference between the conductors. Ipc-2221 Pcb Design Pdf

The IPC-2220 family forms a hierarchical design documentation set, ensuring that general principles are applied correctly to specific technologies. The key documents in this series include: If you are searching for an "IPC-2221 PCB

Prevents electrical arcing, board delamination, and catastrophic thermal failures in high-voltage or high-current applications. Summary and Next Steps

When connecting a component pin to a large copper plane (like ground or power), you must use . Solid copper connections act as massive heat sinks, pulling heat away during soldering. This leads to cold solder joints or "tombstoning" of surface-mount components. IPC-2221 defines the correct geometries for these wagon-wheel-shaped reliefs.
