Abstract:
A flexible conductive polyimide substrate with a fine wiring and a method for manufacturing the same is provided to manufacture a higher value-add flexible conductive polyimide by using an electroless planting and additive method before electroplating. A photosensitive film(14) is adhered to a polyimide(10), and the photosensitive film is developed with exposure and a circuit is patterned by using a photolithography. The surface of selected patterned polyimide patterned is selectively modified, and a metal seed layer(16) is formed on the surface modified polyimide by using an electroless plating. A copper layer is formed on the metal seed layer by using the electroplating, and the photosensitive film is eliminated, and the flexible conductive polyimide substrate is washed.
Abstract:
A wall climbing robot using thrust force is provided to move on the indented and grooved plane by reducing the entering of outdoor air by a sealing unit. A wall climbing robot using thrust force comprises a drive part(300), installed to the edge front part of a main body(500), moving a climbing robot along the surface; a ventilation port, a suction pad(100) having a plurality of sealing parts protruded toward the surface in order to form a suction space by contacting with a surface; a vacuuming part(200) generating thrust force toward the surface on the suction pad by expelling air inside the suction space; a ball contacting with the surface and rolling, and a leveling part(400) having an elastic body compressing a ball against the surface.
