IPC-4562, titled Metal Foil for Printed Board Applications , is an industry-consensus document developed by the Association Connecting Electronics Industries (IPC). It serves as the definitive standard for metallic foils—both unsupported and those supported by carrier films—used in the fabrication of printed wiring boards (PWBs). The standard is widely regarded as an essential tool for laminate and PWB manufacturers, assisting buyers and suppliers in establishing consistency in the understanding, designation, purchasing, and quality conformance inspection of foils.
One of the most important aspects of the IPC-4562 PDF is the reference to "Slash Sheets." These are specific specification sheets that detail the properties of individual material types. When you specify a material on your fabrication drawing (e.g., "Per IPC-4101/126"), you are relying on the framework established in the base standard to ensure consistency.
The document provides detailed specifications for various foil types, including electrodeposited and wrought copper foils, as well as other metallic foils like nickel. The IPC-4562 PDF is an essential resource that ensures every party in the supply chain is speaking the same technical language.
Use the data tables to verify if a supplier's datasheet matches IPC requirements.
| | Nominal Thickness (μm) | |----------------|---------------------------| | 1/8 oz (≈ 35 g/m²) | ≈ 5 μm | | ¼ oz (≈ 70 g/m²) | ≈ 9 μm | | ½ oz (≈ 140 g/m²) | ≈ 18 μm | | 1 oz (≈ 280 g/m²) | ≈ 35 μm | | 2 oz (≈ 560 g/m²) | ≈ 70 μm | | 3 oz (≈ 840 g/m²) | ≈ 105 μm |
Often used in flexible circuits due to its excellent flex fatigue resistance. Surface Profiles and Signal Integrity
When a PCB is qualified to IPC-6012, the copper foil used in its construction must be procured in accordance with IPC-4562, creating a complete chain of traceability from raw material to finished product.
: While copper ( CU ) is the primary metal governed by the standard, the framework accounts for other alloys used in specialized wiring applications.
IPC standards are professional documents and are priced accordingly. Typical costs range from for a single‑user PDF of a document like IPC‑4562, depending on membership status and the specific revision. Multi‑user or enterprise licences are available at higher prices and should be purchased if the standard will be used by more than one person in a networked environment.
When referencing an IPC-4562 PDF, engineers look for the allowable tolerances of specific material properties. The standard dictates strict thresholds for: Profile/Roughness
The IPC-4562 standard does not exist in isolation. It is part of an interconnected ecosystem of IPC specifications that together define the complete PCB manufacturing landscape:
