Abstract
A method for producing curved electronic circuits is provided, including placing adhesive elements between electronic chips and curved bearing surfaces, with the chips disposed between the surfaces and a flexible film, and such that the chips, the elements, and the surfaces are arranged in a single volume to be depressurised towards an environment outside the volume, the volume including empty spaces between the chips and the surfaces, the spaces being in fluid communication with each other within the volume; establishing a pressure difference between an inside and an outside of the volume such that the film applies a pressure on and collectively deforms the chips in accordance with the surfaces; and stopping the establishing of the pressure difference, the chips being collectively maintained against the surfaces by the elements such that a shape of each of the chips conforms to a corresponding shape of each of the surfaces.
