Abstract
Methods and apparatuses for efficiently forming a homogeneous glass layer having uniform thickness and a homogeneous metal layer having uniform thickness are provided. A workpiece is accommodated in a screened container which is rotatable in a predetermined direction. The workpiece in the container is sprayed with an atomized glass slurry or an atomized metal slurry while the container is rotated in order to form a green glass layer or a green metal layer on the workpiece. Simultaneously, hot air is supplied to the workpiece so as to dry the green glass layer or the green metal layer. Thus, the workpiece, typically a ferrite core, can be provided with a homogeneous layer having a uniform thickness. A method for manufacturing an electronic component using the above-described methods and apparatuses is also provided.
