Description

IPC 4411A – Specification and Characterization Methods for Nonwoven Para-Aramid Reinforcement

Covers the nomenclature, definitions and requirements for reinforcement made from nonwoven para-aramid fibers. Para-aramid reinforcement is primarily used in PCBs for HDI and high speed/high frequency applications. IPC-4411A also includes specification sheets, which can be used when selecting and purchasing nonwoven para-aramid reinforcement. Includes the incorporation of 14 new nonwoven para-aramid reinforcement specification sheets and the deletion of four nonwoven para-aramid materials that are no longer commercially available. Due to a test method correction, all specification sheets have been updated.
