Claim of US Patent No. 10,660,211

1. A method for manufacturing an electromechanical structure, the method comprising:producing conductors on a flat film by a continuous roll-to-roll process;
selecting locations on the flat film to attach electronic components based on an amount of projected curvature of the flat film at the selected locations when the flat film is formed into a three-dimensional film;
attaching electronic components on the flat film at the selected locations of the flat film, the electronic components including a number of surface-mount technology (SMT) components;
forming the flat film into the three-dimensional film to minimize separation between the electronic components and curvature of the flat film at the selected locations such that the selected locations of the three-dimensional film on which the electronic components are attached have a curvature that is less than a curvature of other portions of the three-dimensional film, the electronic components not being attached to a location of the three-dimensional film having the greatest curvature; and
injection molding a layer of material on the three-dimensional film by inserting the three-dimensional film into a mold, the layer of material being attached, in the injection molding step, on the surface of the three-dimensional film to create the electromechanical structure.
