Abstract

A flexible electronic assembly including a flexible circuit board and at least one electronic component is provided. The flexible circuit board includes at least one dielectric film layer and at least one patterned conductive layer disposed on the dielectric film layer. The electronic component is disposed on the flexible circuit board and electrically connected to the flexible circuit board. The flexible angle of the flexible electronic assembly is greater than 5 degrees.
