A flat conductor foil is used on which the circuit is etched upon. After equipping this conductor foil with electronic structural elements the conductor foil is folded at predetermined folding edges for adaptation to the device shape. For forming the housing element this circuit unit is sheathed with a plastically mountable hardening synthetic material. The housing element is thereby separated into housing partial parts in such a manner that the housing partial parts may be joined together into a closed housing element when folding the conductor foil. Thereby, the housing partial parts are mounted onto the folding segments of the plane, still unfolded, but equipped conductor foil, whereby (before the folding) folding pieces are obtained for the individual folding pieces which protect the structural elements and the soldering and stabilize the foil for the joining.
In a method for making electronic devices, comprising the steps of providing a flexible conductor foil provided with an etched printed circuit, complementing said foil with electronic structural components, providing folding segments on said foil, folding said foil at predetermined folding edges to adapt to a device shape and inserting said foil with said components into a molding tool having a geometric device shape, and sheathing said foil with a plastic hardenable synthetic material to obtain a housing body, the improvement comprising subdividing the housing body into housing parts in such a manner that the housing parts are joined to a closed housing body during the folding of the conductor foil and said housing parts are mounted as individual synthetic molding parts onto the folding segments of a flat and still unfolded but complemented conductor foil.
