AERIAL MANUFACTURING METHOD AND AERIAL STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide an aerial manufacturing method and an aerial structure.SOLUTION: An aerial manufacturing method includes: a step for providing a ferrite sheet; a step which forms at least one via hole that passes the ferrite sheet and is connected between a first surface and a second surface of the ferrite sheet; a step which forms a non-conductive ink layer on the first surface and the second surface of the ferrite sheet and inside the via hole; a step which applies a replacement process to the non-conductive ink layer and forms a first metal layer on the non-conductive ink layer; and a step which applies onto the first metal layer a thickness growth process forming a second metal layer on the first metal layer and by which both the first metal layer and the second metal layer pass the via hole from the first surface of the ferrite sheet and are extended onto the second surface.
