ELECTROMAGNETIC WAVE ABSORPTION PAINT FOR USE IN ELECTROMAGNETIC COMPATIBILITY MEASURES AND SEMICONDUCTOR APPARATUS AND PRINT CIRCUIT SUBSTRATE APPLYING THEREOF

摘要

PURPOSE: An electromagnetic wave absorption paint for use in an electromagnetic compatibility measures and a semiconductor apparatus and a print circuit substrate applying thereof is provided to secure a competitiveness by advancing a forwarding time of a product. CONSTITUTION: An electromagnetic absorption paint is comprised of an epoxy acrylate, a ferrite, and other additives on a semiconductor chip, a lead line, and a print circuit substrate. To improve an electromagnetic compatibility in level of a print circuit substrate applies the electromagnetic absorption paint, controls a noise generating from the print circuit substrate, and protects the semiconductor from an electromagnetic influence generated from the outside.
