: It yields a high vertical grain structure, offering excellent vertical electrical conductivity and strong adhesion to resin prepregs. Ipc-4562 Pdf May 2026
The IPC-4562 standard, titled , is the foundational global standard governing the quality, testing, and classification of metal foils used in rigid and flexible printed circuit boards (PCBs). Whether you are sourcing copper foil, engineering a high-frequency stack-up, or downloading an IPC-4562 PDF for a compliance audit, understanding this document is critical for ensuring hardware reliability.
Do you need to identify the exact for a specific design?
The IPC-4562 PDF details specific mechanical, electrical, and chemical requirements that foils must meet during quality conformance testing. Purity and Composition ipc-4562 pdf
The standard specifies copper foil thicknesses using the traditional (oz/ft²) convention, with approximate metric equivalents:
Released to update older standards like IPC-MF-150.
IPC-4562 classifies copper foils based on their production method, primarily distinguishing between Electrodeposited (ED) Copper (Type E) for rigid boards and Wrought (Rolled Annealed) Copper (Type W) for flexibility. Grade and Profile Classifications : It yields a high vertical grain structure,
Grade 5 - AR Wrought. Grade 6 - LCR Wrought. 2. P No treatment, BUT stain proofed both sides. 1. N No treatment or stain proofing. Insulectro

The IPC-4562 standard provides specifications and requirements for solderable coatings applied to the mounting surfaces of printed boards. These coatings are crucial for ensuring reliable solder joints when components are mounted on the board. The standard covers various aspects, including the characteristics, testing, and inspection of these coatings to ensure they meet the necessary criteria for assembly and reliability.

This is the technical heart of the standard, covering:
Instead of measuring strictly by microns, the industry often classifies copper by weight per square foot. Common designations include: (~12 µm): Used for fine-pitch HDI boards. 1/2 oz/ft² (~18 µm): Common for standard signal layers.
