| 摘要 |
The present invention relates to a ferrite sheet with a concavo-convex surface, a manufacturing method of the ferrite sheet, and a surface treatment apparatus for the ferrite sheet. The ferrite sheet is provided to have a concavo-convex side, whose average surface roughness is in the range of 0.8-4.0μm, formed on one surface thereof and to evenly transfer heat to the entire surface of each ferrite sheet molded body when the ferrite sheet molded bodies are placed on top of each other and sintered, thereby improving quality of sintered ferrite sheets, lowering a defect rate, and preventing damage to the ferrite sheets when the ferrite sheets are separated. |
