: Primarily Copper (CU) , but also includes Nickel (NI) and other specialized metals.
One of the most practical aspects of the standard is its standardized coding system. A typical call-out (e.g., IPC-4562/3-CU-E-S-LP ) identifies everything a supplier needs to know about the material:
The most recent update, (released in October 2023), addresses modern manufacturing challenges, including the high-speed digital and RF performance needs of today's electronics. 1. Scope and Core Purpose ipc-4562 pdf
: Defines surface roughness, such as Low Profile ( LP ) or Very Low Profile ( VLP ). 3. Key Classification and Quality Levels
: Links to a specific page in the standard containing detailed engineering data (e.g., /3 ). Foil Metal : Usually CU for copper. : Primarily Copper (CU) , but also includes
: Used for procuring foils that will eventually become the conductive layers of rigid, flexible, and rigid-flex PCBs. 2. The IPC-4562 Designation System
The primary goal of IPC-4562 is to establish a common language and quality benchmark between foil manufacturers, laminators, and PCB designers. It ensures that the metal foils—most commonly copper—have consistent electrical, mechanical, and surface properties essential for reliable circuitry. Key Classification and Quality Levels : Links to
IPC-4562 categorizes materials into three quality classes based on the intended reliability of the final product:
(officially titled "Metal Foil for Printed Board Applications" ) is the definitive industry standard that specifies the requirements for metal foils used in the manufacturing of printed circuit boards (PCBs). Published by the IPC (Association Connecting Electronics Industries), it covers both unsupported foils and foils supported by carrier films.
: Indicates if the foil is untreated ( N ), stain-proofed ( P ), or has a single-sided bond treatment ( S ).
