Title: Ic package
Inventor: TOYOMOTO HIDEHARU
IPC: H05K9/00
Filed: 1990-03-01
Abstract: PURPOSE:To shield the unnecessary radiation of radio wave generated from an IC chip, by covering necessary parts of leads in the inside or the outside of an IC package by using ferrite. CONSTITUTION:A lead 2 is covered in the inside of a plastic package 4 by using a ferrite bead 5 wherein ferrite is formed in a bead type, and sealed by using plastic.
