THE MANUFACTURING METHOD OF HIGH PERMEABILITY EMI SUPPRESSION SHEET BY ELECTROMAGNETUC INDUCTION HEATING PROCESS

摘要

PURPOSE: A manufacturing method of high permeability EMI suppression sheet by electromagnet induction heating process is provided to reduce an additional expense due to energy reduction by heating soft magnetic powder in a secondary deformation sheet and pressing it. CONSTITUTION: In a manufacturing method of high permeability EMI suppression sheet by electromagnet induction heating process, a plate of a sheet(100) is supplied. The sheet is passed through a electromagnetic induction heating heater(11) and is heated. A heated sheet is pressed by an upper and lower pressure roller of a calendar and is high dense. The high dense sheet is collected.
