SINTERED FERRITE POWDER, ELECTROMAGNETIC ABSORBING SHEET ASSEMBLY USING THE SAME AND METHOD FOR MAKING THE POWDER AND THE ASSEMBLY

摘要

PURPOSE: A sintered ferrite powder, an electromagnetic absorbing sheet assembly using the same and a method for manufacturing the powder and the assembly are provided to improve the performance of electromagnetic wave absorption by using a ferrite piece. CONSTITUTION: A ferrite powder(116) which is not sintered is mixed with liquid polymer. The liquid ferrite paste is manufactured. A ferrite green sheet is manufactured by hardening or drying the liquid ferrite paste. A sintered ferrite sheet is manufactured by sintering the ferrite green sheet. The sintered ferrite sheet is pulverized.
