: E for electrodeposited or W for wrought (rolled).

: Indicates if the foil is untreated ( N ), stain-proofed ( P ), or has a single-sided bond treatment ( S ).

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

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:

: For products where the major requirement is the function of the completed assembly. : E for electrodeposited or W for wrought (rolled)

IPC-4562 categorizes materials into three quality classes based on the intended reliability of the final product:

: Used for procuring foils that will eventually become the conductive layers of rigid, flexible, and rigid-flex PCBs. 2. The IPC-4562 Designation System : Defines surface roughness

: Ranges from standard grade (1) to high-temperature elongation (3) and annealed-wrought (7).

: Defines surface roughness, such as Low Profile ( LP ) or Very Low Profile ( VLP ). 3. Key Classification and Quality Levels
