 Heavy Copper PCB |
Product Description
The Printed Circuit Board (PCB) industry defines heavy copper as layers exceeding 3 ounces of copper, or approximately 0.0042 inches (4.2 mils) of copper thickness. PCB Designers and Fabricators often use heavy copper when design and manufacturing circuit boards in order to increase current-carrying capacity as well as resistance to thermal strains.
Heavy copper plated vias transfer heat to external heat sinks.
The IPC 2152 is a standard for determining current-carrying capacity in Printed Board Design. The task group was chaired by Michael R. Jouppi.
An ounce of copper thickness on a PCB is defined as the thickness of one ounce (weight) of copper rolled out to an area of one square foot. An ounce of copper is approximately 1.4 mils (0.0014 inch) or 35 um of thickness.
