Ipc-4562 Pdf [better] -
For any professional or commercial application, it is strongly recommended to purchase the standard directly from IPC or one of its authorized resellers.
IPC-4562 is the industry standard titled "Metal-Clad Base Materials for Rigid and Multilayer Printed Boards." It serves as the generic specification for copper-clad laminates and bonding materials. It replaces the older MIL-S-13949 standard and is widely recognized globally.
While IPC-4562A-WAM1 remains widely referenced, IPC-4562B (October 2023) is the most up-to-date version. Always check which revision is invoked by your customer specifications or internal quality documents.
Foils with reduced surface roughness. These are critical for high-speed, high-frequency digital designs, as rough copper surfaces increase signal loss due to the "skin effect." ipc-4562 pdf
To ensure you are using the most current and accurate data, always obtain the standard directly from the IPC (Association Connecting Electronics Industries) official website. Using official copies ensures you are compliant with the latest revisions and amendments.
Reduced roughness for improved fine-line etching.

The minimum values in IPC-4562 are just that — minimums. For critical applications, request actual material property data from your foil supplier.
As signal frequencies increase, the roughness of the copper surface (measured as Rzcap R sub z
: Mandates a strict base metal thickness tolerance, typically permitting up to a 10% maximum reduction from the nominal value. The IPC-4562 standard
The standard works in conjunction with other IPC documents such as (Flexible Base Materials) and IPC-4203 (Flexible Adhesives), creating a comprehensive framework for flexible circuit manufacturing.
These low-profile foils, often referred to as "low-roughness" or "smooth" foils, are essential for maintaining signal integrity in high-speed designs. Engineers designing boards for 5G infrastructure, radar systems, or high-speed data centers should specifically reference these classifications when specifying foils.
This version includes crucial updates, notably bringing back specific light cold-rolled wrought copper foil types (/6. [Cu-W6]) that were previously omitted, ensuring wider applicability for specialty applications.
The IPC-4562 standard, specifically the active IPC-4562B version, defines the quality, classification, and procurement requirements for metal foils used in printed circuit board manufacturing. It covers copper foil designations (e.g., electrodeposited or rolled) and grades, ensuring proper bonding and material performance.
