Hi, Does anyone of the list members employ an Electronic Visions anodic bonder EV 500? We are thinking about building a point electrode for our machine but would prefer to use an existing construction. The electrode should apply voltage to a point in the center of the wafer and apply pressure evenly over the whole wafer surface.
