Abstract:
1. A method of manufacturing a wireless suspension blank using an initial two-layer laminate comprising an insulating layer having first and second sides wherein said first side defines an exposed face, and said initial two-layer laminate further comprising a metallic layer with a spring property which is provided on said second side of the insulating layer, the method comprising a first step of working the metallic layer by the photo etching method to remove metallic material therefrom, a second step of depositing conductive material onto said exposed face of said insulating layer by the semi-additive method in a pattern which partially covers a portion of said exposed face to add a third layer on said initial two-layer laminate and thereby define a resulting three-layer laminate wherein said pattern of said conductive material defines a wiring part for said wireless suspension blank, and a third step of working the insulating layer of said resulting three-layer laminate after the second step by the wet-etching method to remove insulating material therefrom and form the suspension blank.
