FLEXIBLE CIRCUIT STRETCHING

摘要

A method of connecting electrical components and an electronic device formed using this method are disclosed. This method includes stretching a first substrate with a plurality of conductive traces to form a stretched substrate where at least one increased pitch (a spacing between two conductive traces plus a width of one conductive trace) is not greater than 40 microns; and electrically connecting the conductive traces on the first substrate to conductive traces on a second substrate. A device by which this method can be implemented is also disclosed, which includes a base, and platforms and stretchers mounted to the base that are configured to pull opposite ends of the first substrate to align the conductive traces thereon with the conductive traces on the second substrate.
