– As a US‑based national standards body, ANSI sells the same official IPC‑4562B document (ANSI‑approved version).

The purity and quality of the copper affect its thermal conductivity. Often used in flexible circuits due to its

IPC‑4562 is a performance‑based specification that sets the requirements for metal foils used in printed wiring boards (PWBs). It covers , which are later laminated onto a dielectric substrate to create the copper‑clad laminate from which PCBs are manufactured.

This standard provides a standardized material designation system for both supported and unsupported foils, allowing precise specification of material properties. The current revision, , specifically addresses the impact of surface roughness on signal integrity for high-speed and RF applications. Core Foil Types and Manufacturing
