Method of manufacturing wireless suspension blank |
摘要 |
A method of manufacturing a wireless suspension blank wherein three-layered laminate formed of a metallic layer having a spring property and a conductive layer laminated on the metallic layer through an electrically insulating layer are used. The laminate used is a laminate in which an insulating layer is formed of a core-insulating layer and adhesive layers laminated on both sides of the core-insulating layer, and the ratio of higher etching rate to lower etching rate of the respective layers of the insulating layer is between 6:1 and 1:1. The metallic layer and the conductive layer are processed by the photo etching method. The insulating layer is processed by the wet etching method.
