Method for Manufacturing Laminated Coil Devices

Abstract

A method of manufacturing a laminated coil device includes conductors for forming coils and insulation stacking for forming laminated bodies, and further includes the steps of: (A) manufacturing ceramic insulating thin sheets; (B) forming ceramic insulating thin sheets with conductive through-holes; (C) manufacturing coil thin sheets with coil conductors so as to embed the coil conductors inside the ceramic insulating thin sheets; (D) orderly stacking and cutting ceramic insulating thin sheets and coil thin sheets with coil conductors into unit sizes in order to obtain laminated bodies; (E) heating the laminated bodies in order to remove the binder, and then sintering the laminated bodies; (F) coating the conductive paste on the two ends of the laminated bodies so as to fen external electrodes. Thus, the present invention is to provide a manufacturing method of producing a laminated coil power device with low direct current resistance, no delamination, no air space, and no lamination cracking.
