  • Patent number: 11406021
    Abstract: A system for manufacturing an electromechanical structure includes first, second, and third entities. The first entity produces conductors on a planar, flat film. The second entity attaches electronic elements at locations on the film in relation to a three-dimensional shape of the film. The electronic elements include a number of surface mount technology components. The locations of the electronic elements are selected to omit substantial deformation during subsequent forming of the film into the three-dimensional shape. The third entity forms the film into the three-dimensional shape when the electronic elements are supported on the film. The third entity includes one or more machines that are continuously roll-fed, automatically in-precut-pieces-fed, computer numerical control, thermoforming, vacuum former, pressure forming, or blow molding. The first, second, and third entities are arranged relative to one another to manufacture the electromechanical structure.
